Using the Pythagorean theorem:
length of rectangle² = 9² + 6² = 81 + 36 = 117
length of rectangle = √117 = 10.82
length of diagonal² = 2² + 10.82² = 4 + 117 = 121

Answers
Answer:
1. Volume measured in Cubic units (to the third power), Only 3-D objects have volume.
2. Parallel lines have the same slope and will never intersect. The slope of perpendicular lines are the negative reciprocals of each other, they will intersect a 90 degrees
3. Secant is 1/cosX (1 over cosine of x), tangent is sinX/cosX(sine of x over cosine of x)

Susan completed a 26-mile rollerblade marathon in 2.5 hours. If Susan skated at a constant rate, how fast was she skating? A. 10.4 mph B. 8.3 mph C. 6.5 mph D. 4.7 mph
Answers
Answer:
A. 10.4 mph
Step-by-step explanation:
26÷2.5=10.4
Double checking your answer:
If she does 10.4 miles in an hour, she can get 20.8 in two hours
then you add half of how much she can go in an hour which is 5.2 (10.4÷2)
you add it together, and you will get 26 miles in total
(20.8+5.2=26)

Step-by-step explanation:
i first multiplied the cost for one pear by 7, to get how much money was spent on pears out of the 12.70.
Then i took the remaining money and divided it by 2 to get how much each apple costs.
Answer:
1.80
Step-by-step explanation:
1) Price of Pears
[tex]1.30 * 7 = 9.10[/tex] formating: 1.30*7 = 9.10
2) Price of Apples
[tex]12.70 - 9.10 = 3.60[/tex] formating: 12.70-9.10 = 3.60
3) Price of Apples/Kg
[tex]\frac{3.60}{2} = 1.80[/tex] formating: 3.60/2 = 1.80

Answer:
A. 10 units
Step-by-step explanation:
The y-intercept of f(x) is f(0) = -9.
The y-intercept of g(x) is g(0) = g(1)/2 = 1.
The distance between these points is ...
1 -(-9) = 10 . . . units
__
We notice that the common ratio of the table values of g(x) is 4/2=2, so the value for x=0 will be a factor of 2 less than the value for x=1.
find the value of x. round to the nearest degree.
