What is the area of the trapezoid?

Mathematics
1 answer:
storchak [24]3 years ago
7 0

Answer:

A = 70 mm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = \frac{1}{2} h (b₁ + b₂)

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 10, b₁ = 10, b₂ = 4 , then

A = \frac{1}{2} × 10 × (10 + 4) = 5 × 14 = 70 mm²

(a) find the slope m of the tangent to the curve y = 5/ x at the point where x = a > 0.(b) find equations of the tangent line
Trava [24]
<span>(a) the slope of curve is calculated from the derivative of the curve expression y=5/x. In this problem, the slope m=-5/(a^2). (b) x=1, y=5,and m=-5, the tangent line is y-5=-5*(x-1). x=4, y=5/4, and m=-5/16, the tangent line is y-5/4=-5/16*(x-4)</span>

Evaluate each expression for g = -7 and h = 3 and match it to its value. 1. g + h 2 2. g - h 46 3. h - g -21 4. gh -4 5. g + h2
Ivanshal [37]

Answer:

1. -4

2. -10

3. 13

4. -21

5. 2

6. 46

Step-by-step explanation:

To evaluate the expression, substitute g= -7 and h = 3. Then simplify using order of operations.

1.  g-h = -7 + 3 = -4

2. g-h = -7 - 3 = -10

3. h-g = 3 - -7 = 3+10 = 13

4.gh = -7(3) = -21

5. g+h^2 = -7 + 3^2 = -7+9 = 2

6. g^2-h = (-7)^2 -3 = 49 -3 = 46
