Answer:
y = (5/2)x + 4
Step-by-step explanation:
We'll look for an equation in the format y = mx + b, where mn is the slope and b the y-intercept (the value of y when x = 0).
y = mx + b
m is (5/2)
y = (5/2)x + b
We need a value of b that will force the line through point (-2,-1). Enter the point (-2,-1) in the equation and solve for b:
y = (5/2)x + b
-1 = (5/2)(-2) + b
-1 = -5 + b
b = 4
<u>The equation is y = (5/2)x + 4</u>

Answer:
117.8 in²
73.6in³
Step-by-step explanation:
the pipe is in the shape of a open cylinder. the surface area = πdl
π = 3.14
l = length
d = diameter
volume of a cylinder = nr^2h
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
n = 22/7
r = radius = 2.5/2 = 1.25
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
3.14 x (1.25^2) x 15 = 73.6
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
Answer:
Supplementary angles are two angles whose measures add up to 180 degrees. ... Supplementary angles are two angles whose measures add up to 180° . The two angles of a linear pair , like ∠1 and ∠2 in the figure below, are ... If the measure of the angle is twice the measure of the other, find the measure of each angle.
Step-by-step explanation:
just take the - off of the number so it would be 1.4
Answer:
B) 41.7
Step-by-step explanation:
Let , , and . Use the Law of Cosines equation to find angle A=x which is directly across from side :
Therefore, the correct answer is option B, which means you were right!
