Answer:

y = 12 [tex](2.9)^{x}[/tex]

Step-by-step explanation:

The standard form of the exponential function is

y = a [tex](b)^{x}[/tex]

Find a and b by substituting ordered pairs from the table into the equation

Using (0, 12 ), then

12 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), so

a = 12, then

y = 12 [tex]b^{x}[/tex]

Using (1, 34.8 ) , then

34.8 = 12 [tex]b^{1}[/tex] ( divide both sides by 12 )

b = 2.9

Thus exponential function is

y = 12 [tex](2.9)^{x}[/tex]

Answer:

Step-by-step explanation:

let smaller be x

larger number is x+5

4x-3(x+5)=29

4x-3x-15=29

x=29+15=44

x=44

larger number is 49

Answer:

D BOTTOM RIGHT

Step-by-step explanation:

Answer:

$766.28

Step-by-step explanation:

The equation for interest rate is as follows:

[tex]A = P(1 + r)^t\\[/tex]

A = The total amount

P = Initial amount

R = The interest rate

T = Time

Let's plug everything into the equation that is given in the question:

The initial amount = 612

Interest rate = 2.85

Time = 8 years

[tex]A = 612(1+.0285)^8[/tex]

***Just a reminder we move the decimal over twice when working with percents***

Now, lets solve for the total amount:

[tex]A = 612(1.0285)^8\\A = 612(1.252086602)\\A = 766.28[/tex]

Therefore, after 8 years the principal is $766.28.

I hope this helps!!

Answer:

y = 0.35x + 2.5

Step-by-step explanation:

Answer:

f(-6) = 32

f(0) = 2

f(9) = -43

Step-by-step explanation:

Since in this question we are given a function all we have to do is to plug in the values that were indicated in the question and find out what value are we going to get as an output of this function. So we just do the following.....

a)

f(-6) = 2 - 5(-6)

f(-6) = 2 - (-30)

f(-6) = 2 + 30

f(-6) = 32

b)

f(0) = 2 - 5(0)

f(0) = 2 - 0

f(0) = 2

c)

f(9) = 2 - 5(9)

f(9) = 2 - 45

f(9) = -43

Answer:

1). x = 14

2). y = 2.4 cm

Step-by-step explanation:

In the diagram ΔNPQ ~ ΔNLM and NL = 3,

1). ∠P ≅ ∠L [All angles of similar triangle are equal in measure]

   (3x + 18)° = 60°

   3x = 60 - 18

   x = 14

2). Since, both the triangles are similar, corresponding sides will be proportional.

   [tex]\frac{PN}{NL}=\frac{NQ}{NM}[/tex]

   [tex]\frac{y}{3}=\frac{3.2}{4}[/tex]

   y [tex]=\frac{3.2\times 3}{4}[/tex]

   y = 2.4 cm

Answer:

π meters

Step-by-step explanation:

The diameter is 2  meters. Then the radius is 1 meter. So:

A=πr²

  =π(1)²

  =π meters ...............

Answer:

3.14

Step-by-step explanation

the formula of a circle is A=πrxr

2 divided by 2 is 1

1 x 1 = 1

3.14 x 1 = 3.14

thats is!

The solution is,  14.6° is the angle of elevation of a hill whose slope has a length of 345 feet and rises 87 feet.

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

here, we have,

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

here, we have,

given that,

a hill whose slope has a length of 345 feet and rises 87 feet

now, we have to find the angle of elevation of a hill.

so, we get,

perpendicular = 87

hypotenuse = 345

let, the angle of elevation is θ.

we have,

sin θ = 87/345

so, we get,

θ = 14.6°

Hence, The solution is,  14.6° is the angle of elevation of a hill whose slope has a length of 345 feet and rises 87 feet.

Answer:

x = 1/5, y = 6

Step-by-step explanation:

5x + y = 7

y = 7 - 5x

Set equations equal to each other to eliminate y

7 - 5x = 20x + 2

7 = 25x + 2

5 = 25x

x = 1/5

y = 7 - 5(1/5)

y = 7 - 1

y = 6

Answer:

a>12.5.

Step-by-step explanation:

you need to look at the discriminant in the quadratic formula:

[tex]b^{2} -4ac[/tex]

coming from the quadratic polynomial

[tex]ax^{2} +bx+c=0[/tex]

In our case, b=10 and c=2, hence, the discriminant is

[tex]10^2-4*a*2 \\100-8a[/tex]

We will obtain non-real values if the discriminant is less than zero.

Therefore, this condition is written as

[tex]100-8a<0[/tex]

and we must solve for a. It yields

[tex]100<8a\\a>\frac{100}{8} \\a>12.5[/tex]

Hence, the answer is a>12.5.

The values of a that will result in this equation having non-real solutions must e greater than 12.5

Given the quadratic equation  ax^2 + 10x + 2 = 0

For the equation to have non-real solutions, then b^2 - 4ac < 0

From the given equation;

a = a

b = 10

c = 2

Substitute the given parameters into the formula;

10^2 - 4a(2) < 0

100 - 8a < 0

-8a < -100

8a > 100

a > 12.5

Hence the values of a that will result in this equation having non-real solutions must e greater than 12.5

x = 4

Step-by-step explanation:

The parallel segment divides the 2 sides of the triangle proportionally, that is
