Answer:
Step-by-step explanation:
because The curve C crosses the x-axis at the origin and at the points A and B => the x coordinates of A and B are the solution of the equation:
x(x + 4)(x - 2) = 0
<=> x = 0
x = -4
x = 2
because the x-coordinates of the points A and B aren't 0 and the x-coordinate
of A is a negative value
=> the x-coordinate of A is -4
the x-coordinate of B is 2

<u>Calculating h(-5)</u>
This implies that: x = -5
So, we make use of:
Substitute -5 for x
Take LCM
<u>Calculating h(2)</u>
This implies that: x = 2
So, we make use of:
Substitute 2 for x
<em>Use the above explanation to answer your question</em>
To determine the slant height, you will use what you know about surface area of a pyramid.
The surface area of a square Peerman consists of one square, and four congruent triangles.
We know the length of one side on the square base is 18 inches.
The area of the base then would be 324 in.².
Subtract this from the total surface area.
864-324 = 540 in.²
Divide 540 in.² by 4 because there are four congruent triangles.
540/4= 135 in.²
Each triangle is 135 in.². Now use the formula for area of a triangle to solve for the missing slant height.
A = 1/2 x b x h
135 = 1/2 x 18 x h
135 = 9h
h = 15 inches.
The slant height is 15 inches.
Answer:
C. 33.3%
Step-by-step explanation:
Estimated time = 40 minutes
Actual time = 30 minutes
Percent of error = (estimated time - actual time) / actual time × 100
= (40 minutes - 30 minutes) / 30 minutes × 100
= 10 minutes / 30 minutes × 100
= 0.3333 × 100
= 33.3%
Percent of error = 33.3%
C. 33.3%
Answer:-2
