The distance from the origin to the point (−15,20) is
Answer:
25
Step-by-step explanation:
distance between two points is
d=√((x2-x1)^2+(y2-y1)^2)
in this case x2=-15 ,x1=0,y2=20,y1=0
so
d=√((-15-0)^2+(20-0)^2)
d=√(15^2+20^2)
d=√(225+400)
d=√625
d=25

Pierre is using centimeter cubes to build a model. He makes a rectangular prism and that is 20 cubes long 8 cubes tall and 12 cubes wide. What is the volume of pierre's model?
Answer:
1920 cm^3
Step-by-step explanation:
The formula for volume is length x width x height. The length is 20 cubes, the width is 12 cubes, and the height is 8 cubes. You would multiply 20 x 12 x 8 to get 1920.
The cm^3 is important as well as it indicates a volume. Each cube is 1 centimeter and you're multiplying 3 centimeter values (20,12, and 8) by each other so the final answer would be 1920 cm^3.

Step-by-step explanation:
Jason left for school and forgot his math homework on the kitchen table. His mother found the homework 10 minutes after Jason left, and started driving 36 mph to catch him. Jason bikes 12 mph.
a.How long will it take Jason's mother to catch him?
b. How many miles has Jason biked when his mother catches him?
c. If Jason's school is 2.5 miles from his apartment, how fast must his mother drive to catch him at the school door?
Answer: 5 minutes
Step-by-step explanation:
a. Jason's mother to catch him after time of 5minutes.
b. Jason biked for distance of 3miles when his mother catches him.
c. Mother has to drive with speed of 60mph to catch him at the school door, if Jason's school is 2.5 miles from his apartment.
What is speed?
" Speed is defined as the total distance travelled per unit time."
Formula used
[tex]Speed = \frac{total distance travelled}{total time taken}[/tex]
According to the question,
Speed of Jason bike = 12mph
1hour = 12miles
60minutes = 12miles
1minutes = [tex]\frac{12}{60}[/tex] miles
Speed of Jason's mother bike = 36mph
Time after mother found the homework = 10 minutes
After 10 minutes
Jason is at distance = [tex]\frac{12}{60} (10)[/tex]
=2miles
After 15 minutes = [tex]\frac{12}{60} (15)[/tex]
= 3miles
To cover three miles mother has to drive for
1hour = 36miles
60minutes = 36miles
1miles = [tex]\frac{60}{36}[/tex] minutes
3miles = [tex]\frac{60}{36} (3)[/tex]
= 5minutes
If Jason's school is 2.5 miles from his apartment,
Time taken by Jason to reach school door = [tex]\frac{2.5}{12.5} (60)[/tex] minutes
= 12.5 minutes
Time in which mother has to cover distance of 2.5miles
= [tex](12.5-10)[/tex]minutes
= 2.5minutes
Substitute the value in the formula we get,
Speed of mother's bike = [tex]\frac{2.5}{2.5} (60)[/tex] mph
= 60mph
Hence,
a. Jason's mother to catch him after time of 5minutes.
b. Jason biked for distance of 3miles when his mother catches him.
c. Mother has to drive with speed of 60mph to catch him at the school door, if Jason's school is 2.5 miles from his apartment.

What is the run of a 50% slope with a rise of 50 feet?
A. 100 feet
B. 55 feet
C. 25 feet
D. 2500 feet
E. 50 feet
Rise of the line with 50% slope and 50 feet rise = 100 feet
Option (A) will be the answer.
Slope of a line: Slope of a line is given by the expression,
Slope = [tex]\frac{\text{Rise}}{\text{Rus}}[/tex]
Given in the question,
Slope of the line = 50%
= [tex]\frac{50}{100}[/tex]
= 0.5
Rise has been given as 50 feet.
Substitute the values in the expression for the slope,
[tex]0.5=\frac{50}{\text{Run}}[/tex]
Run = [tex]\frac{50}{0.5}[/tex]
= 100 feet
Therefore, run for the given line will be 100 feet.
Option A will be the answer.

how can you tell how many solutions you'll get for a trigonometric equations? does it depend on the value of theta or the range?
Answer: Trigonometric equations are, as the name implies, equations that involve trigonometric functions. Similar in many ways to solving polynomial equations or rational equations, only specific values of the variable will be solutions, if there are solutions at all. Often we will solve a trigonometric equation over a specified interval. However, just as often, we will be asked to find all possible solutions, and as trigonometric functions are periodic, solutions are repeated within each period. In other words, trigonometric equations may have an infinite number of solutions. Additionally, like rational equations, the domain of the function must be considered before we assume that any solution is valid. The period of both the sine function and the cosine function is \displaystyle 2\pi2π. In other words, every \displaystyle 2\pi2π units, the y-values repeat. If we need to find all possible solutions, then we must add \displaystyle 2\pi k2πk, where \displaystyle kk is an integer, to the initial solution. Recall the rule that gives the format for stating all possible solutions for a function where the period is \displaystyle 2\pi :2π:
\displaystyle \sin \theta =\sin \left(\theta \pm 2k\pi \right)sinθ=sin(θ±2kπ)
There are similar rules for indicating all possible solutions for the other trigonometric functions. Solving trigonometric equations requires the same techniques as solving algebraic equations. We read the equation from left to right, horizontally, like a sentence. We look for known patterns, factor, find common denominators, and substitute certain expressions with a variable to make solving a more straightforward process. However, with trigonometric equations, we also have the advantage of using the identities we developed in the previous sections.

For the function y = 7 − 3x, what is the ordered pair for x = 5?
9514 1404 393
Answer:
(x, y) = (5, -8)
Step-by-step explanation:
The value of y is found by evaluating the equation for x=5.
y = 7 -3(5) = 7 -15 = -8
For x = 5, y = -8. As an ordered pair, this is (x, y) = (5, -8).
