Answer:

Step-by-step explanation:

solve E 1st as its the easiest -

<E + 113deg = 180deg

<E = 180 - 113 = 67deg

by exterior angle theorem, <C + <D = 113deg

so 3y+5 + 7y+8 = 113

10y=100

y=10

<C = 3(10)+5 = 35deg

<D = 7(10)+8 = 78deg

Answer:

D = 78

C = 35

DEC = 67

Step-by-step explanation:

Using the theorem, angle D and + angle C = 113 degrees.

Then you can set up the equation 10x + 13 = 113. Then you can find x - it's 10.

Then you plug it back in, and angle D = 78 and angle C = 35

The degree of the function f(x) = -(x + 1)2(2x - 3)(x + 2)2 is<br> , and its y-intercept is
Serggg [28]

Answer:

Degree = 5

Y intercept = 12

Step-by-step explanation:

our function is given as

f(x)=-(x+1)^2 \cdot (2x-3) \cdot (x+2)^2

in the above polynomial our variable is x and it is being multiplied for 5 times. Hence the probable degree for the above polynomial is 5

In order to find the y intercept , we need to put x=0 in f(x) as y intercept is the point at which the function graphically meets y axis and where x = 0

Hence

f(0)=-(0+1)^2 \cdot (2(0)-3) \cdot (0+2)^2

f(0)=-(1)^2 \cdot (0-3) \cdot (2)^2

f(0)=-1 \cdot (-3) \cdot 4

f(0)=3 \cdot 4

f(0)=3 \times 4

f(0)=12

Hence the y intercept is 12 units

Kay was walking along the bridge above the river. She accidentally lost her grip on her camera when she was trying to get it out
nikklg [1K]

Answer:

5 seconds it will hit the water.

Step-by-step explanation:

y=-16t²+400

add -16t² to both sides

-16t²=-400

divide both sides by 16

t²=-25

t=√25

t=5

How Do I solve this I am quite confused
Kazeer [188]

Answer:

$11,714

Step-by-step explanation:

C(x) = 0.7x² - 462x + 87,944

this is a quadratic equation that opens up

the vertex will be the minimum

From the quadratic formula the x coordinate of the vertex is

x = -b/2a

x = 462/(2 * 0.7)

x = 330

Plug in

c(330) = 0.7(330²) - 462(330) + 87,944

c(330) = 11,714

$11,714
