A line passes through the points (4,6) and (6,2) .

siniylev [52]

ANSWER

Yes

No

No

Yes

EXPLANATION

The given line passes through the points,.
$(4,6) \: and \: (6,2)$

We need to determine the slope of this line using these two points.

The formula for finding the slope is

$m=\frac{y_2-y_1}{x_2-x_1}$

$m = \frac{2 - 6}{6 - 4} = - \frac{ - 4}{2} = - 2$

We can now use the formula

$y-y_1=m(x-x_1)$
in the slope intercept form.

If we use the point
$(4,6)$
the equation will be,

$y - 6 = - 2(x - 4)$

If we use the point,

$(6,2)$
we obtain,
$y - 2 = - 2(x - 6)$

Answer:

4.2×10to the 6th or 4,200,000

Step-by-step explanation:

First you have to know that you are multiplying these two numbers. When you multiply exponents like there you add the matissa's (6&7) and add the exponents.

6×10to the 2 * 7×10to the 3rd

42 × 10to the 2+3

42×10to the 5th

Something else you need to know is your matissa cant be higher than 10

So:

4.2 × 10to the 6th is your answer

A cylinder has a radius of 30 ft and a height of 19 ft. What is the exact surface area of the cylinder?

Ad libitum [116K]

$A=2\pi r(r+h)\\
A=2\pi\cdot30\cdot(30+19)\\
A=60\pi\cdot49\\
A=2940\pi\hbox{ ft}^2$
