What is the y-intercept of the graph of the function f(x) = x^2 + 3x + 5?

Semenov [28]

Answer:

(0,5)

Step-by-step explanation:

To find the y-intercept, substitute in 0 for x and solve for y.

y=x^2 + 3x + 5

y=(0)^2 + 3(0) +5

y=0+0+5

y=5

Since there is no x coordinate for a y-intercept, the answer is (0,5)

<h2><em><u>Answer:</u></em></h2>

Total Surface Area = 375 $ft^2$

<h2><em><u>Step-by-step explanation:</u></em></h2>

You need to find the area of the ceiling, floor, the two rectangle walls and the two trapezoid walls

<u>Area of the ceiling:</u>

c = length * width

c = 9*6.5 = 58.5

<u>Area of the 2 rectangle walls:</u>

w = 2(length * width)

w = 2(9 * 8)

w = 2(72)

w = 144

<u>Area of floor:</u>

f = 9 * 7.5

f = 67.5

<u>Area of the two trapezoids:</u>

$t = 2(h * \frac{a + b}{2})$

a = 6.5

b = 7.5

h = 7.5

$t = 2(h * \frac{a + b}{2})$

$t = 2(7.5 * \frac{6.5 + 7.5}{2})$

$t = 2(7.5 * \frac{14}{2})$

$t = 2(7.5 * 7)$

$t = 2(52.5)$

$t = 105$

Total Surface Area = c + w + f + t

Total Surface Area = 58.5 + 144 + 67.5 + 105

Total Surface Area = 375 $ft^2$
