Can you help me please?

Answer:

2 and one half

Step-by-step explanation:

Given

ABC = (4,4),(7,8),(10,4)

A'B'C' = (10,10),(17,20),(25,10)

Required:

Find the Scale Factor

Let the scale factor be represented by s

The relationship between ABC, A'B'C' and s is given as

[tex]s(ABC) = A'B'C'[/tex]

From the given parameters;

A = (4,4) when A' = (10,10)

Using this values;we have

[tex]s * (4,4) = (10,10)[/tex]

Divide both sides by (4,4)

[tex]\frac{s * (4,4)}{(4,4)} = \frac{(10,10)}{(4,4)}[/tex]

[tex]s = \frac{(10,10)}{(4,4)}[/tex]

Divide 10 by 4; This gives 2.5

So,

s = 2.5

Using Point B and B'

B = (7,8) when A' = (17,20)

[tex]s * (7,8) = (17,20)[/tex]

Divide both sides by (7,8)

[tex]\frac{s * (7,8)}{(7,8)} = \frac{(17,20)}{(7,8)}[/tex]

[tex]s = \frac{(17,20)}{(7,8)}[/tex]

Divide 17 by 7 and 20 by 8; This gives 2.5

So,

s = 2.5

Using Point C and C'

C = (10,4) when C' = (25,10)

[tex]s * (10,4) = (25,10)[/tex]

Divide both sides by (10,4)

[tex]\frac{s * (10,4)}{(10,4)} = \frac{(25,10)}{(10,4)}[/tex]

[tex]s= \frac{(25,10)}{(10,4)}[/tex]

Divide 25 by 10 and 10 by 4; This gives 2.5

So,

s = 2.5

Hence, the scale factor is 2 and one-half([tex]2\frac{1}{2}[/tex])

Step-by-step explanation:

Answer:

The x-value is between 2 and 3, and the y-value is between –4 and –5

Step-by-step explanation:

The system of equations:

y = 1/4x - 5

y = -1/2x - 3

is shown in the figure attached. There it can be seen that the solution is (2.667, -4.333). This can be corroborated as follows:

y = 1/4(2.667) - 5 = -4.333

y = -1/2(2.667) - 3 = -4.333

Answer:

A its a

Step-by-step explanation:

Answer:

With a principal = 7200$, interest rate = 14.25% = 0.1425 (compounded quarterly), the amount of money(M) after n years is calculated by formula:

M = Principal x (1 + rate)^time

   = 7200 x (1 + 0.1425/4)^(nx4)

(the rate is divided by 4 and the time is year x 4, because this is compounded quarterly, 1 year has 4 quarters, each quarter has 3 months)

=> After 3 years:

M = 7200 x (1 + 0.1425/4)^(3x4) = 10958.7951$

=> After 10 years:

M =  7200 x (1 + 0.1425/4)^(10x4) =29203.4074$

=> After 14 years:

M =  7200 x (1 + 0.1425/4)^(14x4) = 51129.7818$

=> After 20 years:

M =  7200 x (1 + 0.1425/4)^(20x4) = 118449.862$

Hope this helps!

Answer:

Step-by-step explanation:

First, we need to find 80% of 400

400 x 0.8 = 320

Now 50% of 400 is 200

320 - 200 = 120

It is important to consider salary and benefits because you should consider how much money you need to buy necessities and a few things you want, but you should also look into whether the benefits can wave some of the necessity costs, such as health insurance, etc.

Answer:

D = 6.71

Step-by-step explanation:

For Finding Length, we'll use the distance Formula:

=> Distance Formula = [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

=> D = [tex]\sqrt{(5+1)^2+(3-6)^2}[/tex]

D = [tex]\sqrt{6^2+(-3)^2}[/tex]

D = [tex]\sqrt{36+9}[/tex]

D = [tex]\sqrt{45}[/tex]

D = 6.71

The length of AB is 6.71

Answer:

C ) 10/m⁵

Step-by-step explanation:

In this question, we have to find the product of two terms

First term = 5 m⁻²

Second term = 2 m⁻³

Product of both terms = (5 m⁻²) · (2 m⁻³)

The simple way of calculating product of these two term which involves constants as well as variable is that we multiply the constants together:

5·2 = 10

And we multiply the variables. According to the rules of multiplication, when 2 same constants or variables are multiplied, we can just add their powers to get the result.

(m⁻²) · (m⁻³) = m⁻²⁻³ = m⁻⁵

The product of both terms can be written as:

(product of constants)(product of variables) = (10)(m⁻⁵) = 10/m⁵

So the correct option is C

Answer:

C 10/m^5

Step-by-step explanation:

Answer:

y = 49

Step-by-step explanation:

y ∝ x²

=> y = kx²

Where k is the constant of proportionality

k = 1 (We've found this out in the previous question)

Now,

y = ? when x = 7

The above equation becomes:

=> y = (1)(7)²

=> y = (1)(49)

=> y = 49

Step-by-step explanation:

We can use ratios to solve

1 hour        x hours

------------ = ------------

15 trees      18 trees    

Using cross products

1*18 = 15x

Divide by 15

18/15 = x

1.2 hours

1.2 * 60 minutes = 72 minutes

1 hour 12 minutes

Answer:

Step-by-step explanation:

well you divide 60 (cuz an hour is 60 minutes) by 15 and u get 4

then u multiply 4 by 3 and u get 12

then u add 1 hour and 12 minutes

Answer:

v=0, u=2

Step-by-step explanation:

Label the 2 equations.

5v -u= -2 -----(1)

-v +9u= 18 -----(2)

From (1):

5v -u +2= 0 (+2 on both sides)

5v +2= u (+u on both sides)

u= 5v +2 -----(3)

Subst. (3) into (2):

-v +9(5v +2)= 18

-v +9(5v) +9(2)= 18 (expand)

-v +45v +18= 18

45v -v= 18 -18

44v= 0

v= 0 (÷44 throughout)

Susbt. v=0 into (3):

u= 5(0) +2

u= 2

Answer:

Range: [-1,1] or [tex]-1\leq y \leq 1[/tex]

Domain: [-4,3) or [tex]-4\leq x[/tex] < 3

Step-by-step explanation:

The range is basically all of the y-value the graph takes on, and it takes all the y values from -1 to 1, inclusive

The domain is basically of the x-values the graphs take on, and it takes on x-values from -4 to 3, where -4 is included in the domain and 3 is excluded.

Answer:

Domain: All real numbers greater than or equal to -4 but less than 3.

Range: All real numbers greater than or equal to -1 but less than or equal to 1.

Domain:{all real numbers: -4 [tex]\leq[/tex]x<3}.

Range: {all real numbers: -1[tex]\leq[/tex]y[tex]\leq[/tex]1}.

I just took the test and the answer is n= 6

Answer:

n=6

Step-by-step explanation:

Answer:

BC, CA and AB.

Step-by-step explanation:

m < B = 180 - 77 - 45 = 58 degrees.

The larger the angle the larger is the opposite side.

The angles are 45, 58 and 77 so the shortest side is opposite 35 and is BC.

So from least to greatest the lengths are:

BC, CA and AB.

Answer:

y = 50 x = 10.

Step-by-step explanation:

Let's solve for y first.

We know the line angle 80 and angle 2y-5 is on a 180 degree line.

Now we can do our work:

180 - 85 = 95

2y - 5 = 95

95 + 5 = 100

100 ÷ 2 = 50

2(50) - 5 = 95?

The equation is correct, therefore y = 50.

No we do the same thing for the other angles, 90 and 3x + 55.

Again, 180 line.

180 - 95 = 85

3x + 55 = 85

85 - 55 = 30

30 ÷ 3 = 10

3(10) + 55 = 85?

The equation is correct therefore x = 10.

Thus, y = 50 and x = 10.

Answer:

Step-by-step explanation:

Lets understand how to solve the permutations.

Let the example is [tex]^{5}P_{2}[/tex].

[tex]^{5}P_{2}=\frac{5!}{(5-2)!}[/tex]

     [tex]=\frac{5!}{3!}[/tex]

     = [tex]\frac{5\times 4\times 3\times 2\times 1}{3\times 2\times 1}[/tex]

     =  [tex]\frac{5\times 4\times 3!}{3!}[/tex] [Since 3×2×1 = 3!]

     = 20

Now we will solve the question given,

Number of ways Dave can put 7 cars together = [tex]^{23}P_{7}[/tex]

[tex]^{23}P_{7}=\frac{23!}{(23-7)!}[/tex]

       [tex]=\frac{23!}{16!}[/tex]

       [tex]=\frac{23\times 22\times 21\times 20\times 19\times 18\times 17\times 16!}{16!}[/tex]

       [tex]=23\times 22\times 21\times 20\times 19\times 18\times 17[/tex]

       [tex]=1235591280[/tex]

Answer:

Proportion of blue marbles in in sample = 9/40

Step-by-step explanation:

Total number of blue marbles in a jar is given by 25%

Lets find the probability of blue marble in the jar of the given sample:

Proportion of blue marbles in in sample = Total number of blue marbles in sample/ Total number of marbles in sample

Where

Total number of blue marbles in sample = 9

Total number of marbles in sample = 9 + 15 + 16

Total number of marbles in sample = 40

SO

Proportion of blue marbles in in sample = 9/40

or

Proportion of blue marbles in in sample = 9/40

Answer:

The answer is option B.

f(x) = 5x² - 3

g(x) = x² - 4x - 8

(f - g)(x) = 5x² - 3 - ( x² - 4x - 8)

= 5x² - 3 - x² + 4x + 8

= 4x² + 4x + 5 option B

Hope this helps.
