If f(x) = −4x 2 + 15, then f(−3)

Answers

Answer 1

Answer:

-21

Step-by-step explanation:

f(-3) = -4(-3)² + 15 = -4(9) + 15 = -36 + 15 = -21

Answer 2

Answer:

f(-3) = -21

Step-by-step explanation:

f(x) = −4x²+ 15

f(-3) = -4(-3)² + 15

f(-3) = -4(9) + 15

f(-3) = -36 + 15

f(-3) = -21

What pair of angles must have the same measure?I'll give brainliest if its correct.

Answers

Answer:

[tex]\text{(C) }\angle 2\text{ and }\angle 7[/tex]

Step-by-step explanation:

Angle 2 corresponds with angle 6 and since all corresponding angles are equal, [tex]\angle 2=\angle 6[/tex]. Angle 6 and angle 7 happen to be vertical angles (opposite side of an intersection of two lines). Since all vertical angles are also equal, [tex]\angle 6=\angle 7[/tex] and by substitution, we have: [tex]\implies \boxed{\text{(C) }\angle 2\text{ and }\angle 7}[/tex]

Angle 2 and 7 is the answer!!

You invest $10,200 in an account that compounds continuously at an annual percent interest rate of 6.25%. How long does it take to double your money?

Answers

Answer:

11.09 years

Step-by-step explanation:

Given data

Principal P= $10200

Rate= 6.25%

Double the principal A = $20,400

The expression for the time taken is

t= ln(A/P)/r

t= ln(20400/10200)/0.0625

t= ln(2)/0.0625

t= 0.69314/0.0625

t= 11.09024 years

Hence the number of years is 11.09 years

Describe the behavior of the function h around its vertical asymptote at x=-6.

Answers

Answer:

B

Step-by-step explanation:

One good way to look at this is to graph both polynomials, as shown in the picture. A tip to help graph is to factor it out and work from there. For example, in x²+14x+48, we can gather that (x+6)(x+8) is the same thing, and it is easier to then graph it. Similarly, for x²+12x+36, we can factor it out as (x+6)² .

When x²+12x+36 approaches 6, it is getting really close to 0, but it stays positive. When x²+14x+48 approaches 6 from the negative side, it is also getting close to 0, but it's negative. When x²+14x+48 approaches 6 from the positive side, it is positive.

Therefore, on the negative side, there is one positive and one negative (dividing a negative by a positive is negative, and a positive by a negative is also negative) , and on the positive side, there are two positives, forming one answer.The answer is therefore B

D. 49 m
E. 189 m

Answers

Answer:

A) 14.45 m is the answerrrerreer

Answer:

17m

Step-by-step explanation:

We can use  the Pythagorean theorem

a^2+b^2= c^2  where a and b are the legs and c is the hypotenuse

8^2 + 15^2 = c^2

64+ 225 = c^2

289 = c^2

Taking the square root of each side

sqrt(289) = sqrt(c^2)

17 =c

8x+20y=-120 as slope

Answers

Answer:

y = -2/5x -6

slope is -2/5

y intercept -6

Step-by-step explanation:

8x+20y=-120

Slope intercept form is y = mx+b where m is the slope and b is the y intercept

Subtract 8x from each side

8x -8x+20y= -8x-120

20y = -8x - 120

Divide by 20

20y/20 = -8x/20 -120/20

y = -2/5x -6

What is the decay factor of the exponential function
represented by the table?

Answers

Given:

The table of values of an exponential function.

To find:

The decay factor of the exponential function.

Solution:

The general form of an exponential function is:

[tex]y=ab^x[/tex]              ...(i)

Where, a is the initial value and [tex]0<b<1[/tex] is the decay factor and [tex]b>1[/tex] is the growth factor.

The exponential function passes through the point (0,6). Substituting [tex]x=0,y=6[/tex] in (i), we get

[tex]6=ab^0[/tex]

[tex]6=a(1)[/tex]

[tex]6=a[/tex]

The exponential function passes through the point (1,2). Substituting [tex]x=1,y=2,a=6[/tex] in (i), we get

[tex]2=6(b)^1[/tex]

[tex]2=6b[/tex]

[tex]\dfrac{2}{6}=b[/tex]

[tex]\dfrac{1}{3}=b[/tex]

Here, [tex]b=\dfrac{1}{3}[/tex] lies between 0 and 1. Therefore, the decay factor of the given exponential function is [tex]\dfrac{1}{3}[/tex].

Hence, the correct option is A.

The angle 1 and the side equal to 72° together equal 180. 72 + x = 180 using the subtraction property of equality we can conclude that x = 108.

Side 2 is parallel with 72° making them equal and Side 3 is parallel with 108° making them equal.

Side 1 = 108°
Side 2 = 72°
Side 3 = 108°
Side 1=108

Cameron sponsored a fundraiser that 582 people attended. He raised 6,480. He charged $15 for balcony seats and $10 for ground seats. How many people bought balcony seats (b) and how many bought ground seats (g)?

15b + 10g = 6,480
b + g = 582

Answers

Answer:

132 people bought balcony seats and 450 people bought ground seats.

Step-by-step explanation:

We want to solve the system of equations:

[tex]\left\{ \begin{array}{ll} 15b+10g=6480 \\ b+g=582 \end{array} \right[/tex]

We can solve this by using substitution. From the second equation, we can subtract b from both sides:

[tex]g=582-b[/tex]

In the first equation, we can divide both sides by five:

[tex]3b+2g=1296[/tex]

Substitute:

[tex]3b+2(582-b)=1296[/tex]

Distribute:

[tex]3b+1164-2b=1296[/tex]

Simplify:

[tex]b+1164=1296[/tex]

Solve for b:

[tex]b=132[/tex]

Using the modified equation again, substitute:

[tex]g=582-(132)[/tex]

Evaluate:

[tex]g=450[/tex]

Therefore, 132 people bought balcony seats and 450 people bought ground seats.
