The measure of an angle is 137.4°. What is the measure of its supplementary angle?
OverLord2011 [107]

Answer:

42.6 degrees

Step-by-step explanation:

A supplementary angle is one that adds to the other one so the sum is 180 degrees. So 180-137.4=42.6

Find the equation of the line with x-intercept 4 and y-intercept -1 in slope-intercept<br> form.
Nastasia [14]

Answer:

Step-by-step explanation:

The slope-intercept form is y=mx+b, where m is the slope and b is the y-coordinate of the y-intercept, so we can already conclude that b=-1.

This results in y = mx - 1

We also have the x-intercept, and we know that the y-coordinate of an x-intercept is always 0. This means that we have the point (4,0). Substitute this into the formula to generate m:

0 = 4m - 1

4m = 1

m = 1/4

thus y = \frac{1}{4}x - 1

Find the acute angles between the curves at their points of intersection. (the angle between two curves is the angle between the
amm1812
At point of intersection the two equations are equal,
hence, 6x³ =6x²
           6x³-6x²=0
           6x²(x-1)=0 , the values of x are 0 and 1
The points of intersection are therefore, (0,0) and (1,6)
To find the slopes of the tangents at the points of intersection we find dy/dx
for curve 1, dy/dx=12x, and the other curve dy/dx=18x²
At x=0, dy/dx=12x =0, dy/dx=18x² = 0, hence the angle between the tangents is 0, because the tangents to the two curves have the same slope which is 0 and pass the same point (0,0) origin.
At x=1, dy/dx =12x = 12, dy/dx= 18x² =18, Hence the angle between the two tangents will be given by arctan 18 -arctan 12 
                                      = 86.8202 - 85.2364 ≈ 1.5838, because the slope of the lines is equal to tan α where α is the angle of inclination of the line.

Write a function rule that represents each sentence.1. y is 5 less than the product of 4 and x. 2. 2.5 more than the quotient of
Mrac [35]
1. It is important to go through each of the words given in the question to get through to the actual answer. The function will be:
y= (4 * x) - 5
  = 4x - 5

2. The function of this statement will be
(h/3) + 2.5 = w

1. Let us assume the price of a pizza = p
    From the first part we can write 
    p = $6.95
    On adding the price of each topping "t" we get
    p = $6.95 + ($0.95) * t
       = <span>$6.95 + $0.95t</span>
    I hope it helps you.
