b. It is a segment that touches the circle in exactly one point and makes a right angle with the radius.
Nothing really to be explained, it just the definition of the tangent.
Answer:
16.65$
Step-by-step explanation:
Well, if the cement block is going to get painted, then you would have to find the surface area of that rectangular solid.
Multiply 4.5 by 7.25 to get the area of one side, then multiply that answer by 2 to get the area of the side opposite the given side. You'd end up with the area for two congruent sides.
Next, multiply 4.5 by 6.5. Multiply the sum by 2, since there is another congruent side opposite that.
Lastly, multiply 6.5 and 7.25, since they are the only numbers left to multiply anyway. Multiply the product by 2.
Your work should look somewhat like this:
4.5 x 7.25 = 32.625 (x2)
4.5 x 6.5 = 29.25 (x2)
6.5 x 7.25 = 47.125 (x2)
32.625 + 29.25 + 47.125 = 109
Multiply 109 by 2 (there are 6 sides to this prism; 3 are listed, so multiply 2 to get the area of the other 3)
FINAL ANSWER: 218 feet squared
The residual value when x = 4 is 6.72 if the line of best fit to be y = 2.78x – 4.4
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Given the function:
y = 2.78x - 4.4
When x = 4:
y = 2.78(4) - 4.4 = 6.72
The residual value when x = 4 is 6.72 if the line of best fit to be y = 2.78x – 4.4
