Answer:

28%

Step-by-step explanation:

Emma's length at birth = 20.5 inches.

Her length after 6 months = 26.25 inches

Change in Emma's length = (26.25 - 20.5) inches

                                            = 5.75 inches

Percentage change in her length = [tex]\frac{Change in her length}{Her length at birth}[/tex] × 100

                                                        = [tex]\frac{5.75 inches}{20.5 inches}[/tex] × 100

                                                        = 28.049%

The approximate percent change in her length is 28%.

As per above, the nth term is: aₙ= -2n²

The sequence:

Answer:

(x+1)(x-14)(x+3)

Step-by-step explanation:

The first step in factorising polynomials is to find the smallest factor first. The way to do this is with trial and error. Lets see if x+1 is a factor.

According to the factor theorem, (x-a) is a factor of P(x) if and only when P(a) = 0

In this case we will use f(x) = ((x)^3)-((10x)^2)-53x-42

f(-1) = 0

Therefore (x+1) is a factor of the polynomial.

Now we divide the polynomial with (x+1) via long division to get (x^2)-11x-42.

We now factorise (x^2)-11x-42 using whatever method you would like. I'm going to use the AC method, where we find a number that multiplies to AC and adds to B, In this case AC = -42, and B = -11.

Therefore (x^2)-11x-42 factosied is (x-14)(x+3)

Now merge (x+1) with (x-14)(x+3)

The final answer is (x+1)(x-14)(x+3)

If this has helped, please consider making this the Brainliest answer!

Answer:

(x+1)(x+3)(x-14)

Step-by-step explanation:

=> x³-10x²-53x-42

We'll break 10x² and -53x into parts

=> x³+x²-11x²-11x-42x-42

Taking common

=> x²(x+1)-11x(x+1)-42(x+1)

Taking x+1 as common will make it

=> (x+1)(x²-11x-42)

Using mid term break formula

=> (x+1)(x²-14x+3x-42)

=> (x+1)[x(x-14)+3(x-14)]

Taking (x-14) as common

=> (x+1)(x+3)(x-14)

This is the required factorized form.

Hope it helps :)

Answer:

79

Step-by-step explanation:

       78

         ---------

7 |       62 03 

          49

         ----------

148 |   13 03

          11 84

         -----------

            19

         -----------

78^2 = 6084.

We observe that 78^2 < 6203.

79^2 = 6241.

We observe that 79^2 > 6203.

Hence the number to be added to 6203 is 6241 - 6203 = 38.

6203 + 38 = 3241

                  = 79 * 79

                  = 79.

Therefore 38 should be added to 6203 to obtain a perfect square.

Answer:

1453/23328

Step-by-step explanation:

Since we are going to have at least three 5's to obtain a number divisible by 125, the number of ways we can combine exactly three 5's is ⁶C₃. The number of ways we can combine the remaining dice without containing a five is 5³, since there are 3 remaining dice. So, for exactly three 5's , we have ⁶C₃ × 5³. Similarly, for exactly four 5's, we have ⁶C₄ × 5² (5² since there are two dice left). Also, for exactly five 5's, we have ⁶C₅ × 5¹ (5¹ since there are one die left). Finally, for exactly six 5's, we have ⁶C₆ × 5⁰(5⁰ since there are no dice left without a five).

So, for at least three 5's, we have ⁶C₃ × 5³ + ⁶C₄ × 5² + ⁶C₅ × 5¹ + ⁶C₆ × 5⁰

= 20 × 125 + 15 × 25 + 6 × 5 + 1 × 1

= 2500 + 375 + 30 + 1

= 2906 ways

The total number of ways of combining the six dice is 6⁶

So, the probability of obtaining a product divisible by 6 is thus P = 2906/6⁶ = 2906/46656

= 1453/23328

Using the binomial distribution, it is found that there is a 0.0536 = 5.36% probability that the product is divisible by 125.

The product will be divisible by 125 in two outcomes:

For each dice, there are only two possible outcomes, either the result is 5, or it is not. The results of the dices are independent, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability that the product is divisible by 125 is:

[tex]p = P(X = 3) + P(X = 6)[/tex]

Hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{6,3}.(0.1667)^{3}.(0.8333)^{3} = 0.0536[/tex]

[tex]P(X = 6) = C_{6,6}.(0.1667)^{6}.(0.8333)^{0} \approx 0[/tex]

Then:

[tex]p = P(X = 3) + P(X = 6) = 0.0536 + 0 = 0.0536[/tex]

0.0536 = 5.36% probability that the product is divisible by 125.

Answer:

The median would be 10. The number in between 9 and 11 would be 10

Step-by-step explanation:

The numbers in order would be 5,5,7,9,11,14,16,18. Since there is an even amount of numbers in the sequence, the middle two numbers are 9 and 11. You add them together to get 20 then divide by 2. So the answer would be 10.

Answer:

28.27 ft²

Step-by-step explanation:

Area of the circle is equal to πr².

Where r is the radius.

π(3)²

9π = 28.274334

The area of the circle is 28.27 ft² approximately.

Answer:

see below

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

A = pi (3)^2

A = 9pi

Letting pi be approximated by 3.14

A = 9 * 3.14

A=28.26 ft^2

If we use the pi button

A = 28.27433388 ft^2

Answer:

Since we know the number 8 is in all 3 shapes we know D is 8. The clue after that tells us that C is brown. Since brown, purple, and orange are in the circle that means that D is either purple or orange but since the purple section has 5 and D is 8 we know that D is orange, B is purple, and B is 5. Since the blue section is only in the triangle, we know that F is blue. From the last clue we know that A is green. Since green and pink are in the rectangle only, G is pink. Using the third clue we know that E and F are 6 and 1 but we don't know which is which. Thankfully, since we know F is blue and the yellow section is 1, we can conclude that F is 6, E is yellow, and E is 1. We know that A and G are 3 and 4 but we don't know which is which, and we know C is 9. Since A's number is smaller than G's we know that A is 3 and G is 4.

Answer:

Answer = 2,335.52

Step-by-step explanation:

Given amount : 1,885

Finding 5%  of 1,885 =  0.05 * 1,885

5% of 1885 = 94.25

Now 1885 increased by 5% =  1,885 + 94.25= 1,979.25

Finding further 18% of 1,979.25 = 0.18 * 1,979.25

18% of 1979.25 = 356.265

Final amount = 1,979.25 + 356.265

Final Amount = 2,335.515

Now Rounding off the answer to 2 decimal points we get:

Answer = 2,335.52

(As the third digit after decimal is 5 so previous will be added b 1)

Answer:

The range of the function is all real numbers greater than or equal to -1.

Step-by-step explanation:

Second order polynomials are continous and have an absolute maximum or minimum that restricts the set of the range associated with the function. A fair approach to estimate the range is rewritting the expression into parabola form, which is:

[tex]y - k = C \cdot (x-h)^{2}[/tex]

Where:

[tex]C[/tex] - Vertix parameter, dimensionless. If [tex]C > 0[/tex], then vertix is an absolute minimum, but if [tex]C < 0[/tex], vertix is an absolute maximum.

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]h[/tex] - Location of the vertix with respect to the independent variable, dimensionless.

[tex]k[/tex] - Location of the vertix with respect to the dependent variable, dimensionless. This value restrics the set corresponding to the range of the polynomic function.

First, we have to expand polynomial into its standard form:

[tex]y = (x-4)\cdot (x-2)[/tex]

[tex]y = x^{2}-6\cdot x +8[/tex]

Now, we are going to complete the square and factorize the resultant expression until parabola form is obtained:

[tex]y = x^{2}-6\cdot x + 9 -9 + 8[/tex]

[tex]y = (x-3)^{2} -1[/tex]

[tex]y + 1 = 1 \cdot (x-3)^{2}[/tex]

Since the vertix parameter is positive, then vertix is an absolute minimum. The location of the vertix with respect ot the depedent variable is [tex]k = -1[/tex]. Therefore, the range of the function is all real numbers greater than or equal to -1.

the coordinates of y are (1,-4)

Step-by-step explanation:

by using midpoint formula

z(x,y)=([tex]\frac{x1+x2}{2}[/tex],[tex]\frac{y1+y2}{2}[/tex])

putting the values of coordinates

(3,-1)=[tex]\frac{5+a}{2}[/tex],[tex]\frac{2+b}{2}[/tex]

separating the coordinates

3=[tex]\frac{5+a}{2}[/tex]                and           -1=[tex]\frac{2+b}{2}[/tex]

3×2=5+a                and      -1×2=2+b

find how much it costs to buy 45 certificates, subtract that from the original budget then divide that by 6.25 and remove the decimals

Answer:

He can buy up to 55 care packages

Step-by-step explanation:

c = certificates

p = packages

6.25p + 4.50c ≤ 550

c = 45

6.25p + 4.50(45) ≤  550

6.25p + 202.50 ≤  550

Subtract 202.50 from each side

6.25p + 202.50 -202.50 ≤  550-202.50

6.25p  ≤  347.50

Divide each side by 6.25

6.25p/6.25  ≤  347.50/6.25

p  ≤  55.6

Since we cannot buy part of a care package

p ≤55

Answer:

a. p= 36/(m + 1)

b. p = 3

Step-by-step explanation:

If p varies inversely as (m + 1)

then p = k × 1/(m + 1). {Where k is the constant}

when p = 4, m = 8, that means 4 = k/(8 + 1)

4 × 9 = k and k = 36

a. Therefore the equation is p= 36/(m + 1)

b. When m = 11,

p = 36/(11 + 1)

p = 36/12

p = 3

Answer:

The domain of y = f(x) is [0,8]

Step-by-step explanation:

Since the straight line with negative slope begins on the y-axis at (0. 9) and exits the plane at (8, 1), we get is domain from the minimum and maximum values of x for which the function is valid.

So, the minimum value of x at which the function is valid is x = 0 and the function is y = f(0) = 9.The maximum value of x at which the function is valid is x = 8 and the function is y = f(8) = 1.

So, the domain of the function y = f(x) is [0,8]

Answer:

y = f(x) is [0,8]

Step-by-step explanation:

Answer: [tex]y \leq \frac{1}{2} x+3[/tex]

Step-by-step explanation:

If a function has a positive slope, that means the y value is increasing with respect to x. As you go down the x-axis, the y value will continuously increase.

First you want to plot the two sets of coords that they gave you, or else you wont know what the line looks like. Or, you could visually do it in your head. We're going down -4 on the x-axis and down 1 on the y-axis. Then for our second coords, we are going to 0 on the x-axis, then up 3 on the y-axis.

You could plot this for yourself, but im going to do it in my head for simplicity. We also need to find the slope of this function in order for us to find the y-intercept. The slope is change in y divided by the change in x. Subtract the initial position from the final position.

3 - 1 = 2

0 - (-4) = 4

2/4 = 1/2

The new equation is:

[tex]y=\frac{1}{2} x+b\\plugin(0,3)\\3=\frac{1}{2} (0)+b\\b=3[/tex]

Everything is shaded below and to the right of the line. They said the line was solid, so that means less than or equal to, [tex]\leq[/tex]

Step-by-step explanation:

A polynomial divided by factor (x - h) has a remainder given by f(h)

Here the divisor is (x - 2), thus f(2) gives the remainder, that is

2³ + 2(2)² - 7(2) + a = 4 ← 4 being the remainder

8 + 8 - 14 + a = 4, that is

12 + a = 4 ( subtract 12 from both sides )

a = - 8
