to find the slope for the first one, use the formula $\frac{y2-y1}{x2-x1}$

(It's the slope formula)

so... $3=y2, 3=y1, 2=x2, 10=x1$

then plug in... $\frac{3-3}{2-10} =\frac{0}{-8} = 0$

this line has a slope of 0

As for the miles problem, to find mph, the miles have to be at 1.

so... $4x=242\\x=60.5$

therefore, he drove 60.5 mph

A sequence is formed by adding 1 to each square number.

MrRa [10]

Answer:

32 nd term

Step-by-step explanation:

The formula for the sequence is

n² + 1 ( that is 1 added to each square number )

Equate to 1025 and solve for n

n² + 1 = 1025 ( subtract 1 from each side )

n² = 1024 ( take the square root of both sides )

n = $\sqrt{1024}$ = 32

How do you find the missing height of a triangle?

g100num [7]

Answer:

Use the Pythagorean theorem

Step-by-step explanation:

The pythagorean theorem is $a^{2} +b^{2} =c^{2}$ where a is a height, b is a height, and c is the hypotenuse, which is the longest side of a triangle. For example, if the triangle has two side with lengths of three and four we would put them into the equation to get:
