Answer:

C. y=-3/10x+1/2

Step-by-step explanation:

First we need to find the Y intercept (b) and the slope(m).

To find the Y intercept, look and find where the line crosses the Y axis. (the line going up and down). It does at 1/2

To find the slope, take 2 points and plug them into the slope formula (y2-y1/x2-x1) Im using the points (-5,2) and (5,-1). once these are plugged into the formula youre given: -1-2/5-(-5) which equals -3/10.

Now the formula for slope intercept is y=mx+b. so now you just plug in the numbers. y=-3/10x+1/2

Given that the prime factorisation of 198 is 2x(3×3)x11. State the minimum integer value of

mylen [45]

Answer:

Step-by-step explanation:

198 = 2×3²×11

For 198n to be a perfect square, each prime factor must have an even exponent. So the smallest 198n would be:

198n = 2²×3²×11²

198n = 4356

n = 22

Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (0, 0)

Point (1, -2)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [SF]: $\displaystyle m=\frac{-2-0}{1-0}$
[Fraction] Subtract: $\displaystyle m=\frac{-2}{1}$
[Fraction] Divide: $\displaystyle m=-2$

the height of a cylinder is three times the diameter of the base . The surface area of thre ylinder is 126pi ft^2. What is thr r

Over [174]

The answer is 3 ft

The surface area (SA) of a cylinder with radius r and height h is:
SA = 2πr² + 2πrh = π(2r² + 2rh)

We have:
SA = 126π ft²
h = 3 * d
d = 2r
h = 3 * 2r = 6r

126π = π(2r² + 2rh)
126 = 2r² + 2rh
126 = 2r² + 2r * 6r
126 = 2r² + 12r²
126 = 14r²
r² = 126/14
r² = 9
r = √9
r = 3
