Answer:
2
Step-by-step explanation:
square have the same side length is the area is 4 you would have to find what number that you can multiply by itself twice (ex: 2x2) that gets you four the only number does that is 2
Answer:
{- 1, 0, 4 }
Step-by-step explanation:
the range is the y- coordinates of the plotted points
the coordinates of the points are
(- 4, - 1 ) , (1, 0 ) , (1, 4 ) with y- coordinates - 1, 0, 4
then range is { - 1, 0, 4 }
Answer:
Option D
Step-by-step explanation:
The questions which involve calculating the angles and the sides of a triangle either require the sine rule or the cosine rule. In this question, the two sides that are given are adjacent to each other and the given angle is the included angle. This means that the angle is formed by the intersection of the two lines. Therefore, cosine rule will be used to calculate the length of b. The cosine rule is:
b^2 = a^2 + c^2 - 2*a*c*cos(B).
The question specifies that a=42, B=120°, and c=35. Plugging in the values:
b^2 = 42^2 + 35^2 - 2(42)(35)*cos(120°).
Simplifying gives:
b^2 = 4459.
Taking square root on the both sides gives b = 66.78 (rounded to the two decimal places).
This means that the length of the third side is 66.78 units!!!
Answer:
5 5/8 miles per hour
Step-by-step explanation:
Martin can run 3 ¾ miles in 2/3 of an hour. Write a unit rate to describe the situation and explain the context.
We are asked to write the unit rate , this means we are to find out how many miles he can run per hour
Hence,
2/3 hour = 3 3/4 miles
1 hour = x
Cross Multiply
2/3 hour × x = 3 3/4 miles × 1 hour
x = 3 3/4 miles × 1 hour/ 2/3 hour
x = 3 3/4 ÷ 2/3
x = 15/4 ÷ 2/3
x = 15/4 × 3/2
x = 45/8
x = 5 5/8 miles per hour
