Answer:
perimeter = 43.96 m
area = 153,86 m2
Step-by-step explanation:
d = 14 m
r = 7 m
perimeter = 2πR = 43.96 m
area = π
= 153,86 m2
The <em>correct answer</em> is:
interpolating
Explanation:
Interpolation is a method of constructing new data points within the range of a discrete set of known data points.
This would include inserting data points between two known points and extending a data set.
Answer:
One big reason why a car’s total price won’t match the price on its window sticker relates to fees charged by a car dealership and the automaker. For example, although a car may cost $19,995 according to the window sticker, that figure might be the price before the addition of a destination charge, which is a pricy manufacturer’s fee that can add up to $1,000 to the price. A dealer may also charge a documentation fee to prepare the vehicle’s documents for sale, and this figure can sometimes cost as much as $500. There are mandatory government fees too, such as the cost to process the car’s title work or change the registration to your name.
Step-by-step explanation:
Dealer and manufacturer fees usually aren’t the biggest add-ons to a car’s purchase price. The priciest addition typically comes in the form of taxes, since most states levy a sales tax on the entire price of a new or used vehicle. Since sales taxes can range as high as 8-10 percent in some areas, this can easily add thousands of dollars to your vehicle’s purchase price. For example, a $20,000 car purchased in an area with a 7 percent sales tax will cost an extra $1,400 on top of the purchase price, while a $30,000 car bought in a place with a 9 percent sales tax will see a whopping $2,700 price boost before you can drive it home.
a. Does her equation make sense?
If so, explain why her equation must be true. If it is not correct, determine what is incorrect and rewrite the equation.
b. If you have not already done so, solve her equation, clearly showing all your steps.
What are the measures of the two angles?
c. Verify that your answer is correct.
The figure is attached below
Given : (2x+1) + (x-10) = 90
(a) Yes , the equation make sense because right angle is 90 degree. Also two angles make up 90 degree.
(b) solve for x, (2x+1) + (x-10) = 90
2x+1 + x-10 = 90 ( combine like terms)
3x -9 = 90 (add 9 on both sides)
3x = 99
x = 33
One angle is 2x+1 = 2(33) +1 = 67 degrees
Another angle = x-10 = 33-10 = 23 degrees
(c) one angle + another angle = 90
67 + 23 = 90
So verified
Answer:
The slope is -4/7 and the y-intercept is -8/7.
Step-by-step explanation:
y+4=-4/7(x-5)
7y+28=-4(x-5)
7y+28=-4x+20
7y=-4x-8
y=-4/7x-8/7
