Answer:
<u>C. 108.5 square feet</u>
Step-by-step explanation:
<u>Area of the deck</u>
- Area (left triangle) + Area (rectangle) + Area (right triangle)
- 1/2 x 6 x 7 + 10 x 7 + 1/2 x 7 x 5
- 21 + 70 + 17.5
- 91 + 17.5
- <u>108.5 square feet</u>
I believe it’s b: right triangle
Answer:
No
Step-by-step explanation:
When there are two or more points on the same vertical line, the relation shown is <em>not a function</em>.
Graph 1 has two points at x=-4.
Graph 2 has two points at x=4.
Neither shows a relation that is a function.
If H = 4, we simply plug 4 into the position of h in the expression.
48 + 25 * 4
48 + 100

If <em>x</em> = -1, you have
2(-1) + 3 cos(-1) + <em>e</em> ⁻¹ ≈ -0.0112136 < 0
and if <em>x</em> = 0, you have
2(0) + 3 cos(0) + <em>e</em> ⁰ = 4 > 0
The function <em>f(x)</em> = 2<em>x</em> + 3 cos(<em>x</em>) + <em>eˣ</em> is continuous over the real numbers, so the intermediate value theorem applies, and it says that there is some -1 < <em>c</em> < 0 such that <em>f(c)</em> = 0.
