A circle has a radius of 26.85 inches. What is the circumference of this circle? Use 3.14 for pi. Round your final answer to the

AVprozaik [17]

Hello!

To find the circumference you use the equation $2 \pi r$

r is the radius

Put 3.14 in for pi

2(3.14)(26.85) = 168.618

Round the the nearest tenth

The answer is 168.6

Hope this helps!

Whats the slope of (-3,4) (0, 0)

Maurinko [17]

Answer:

slope = $-\frac{4}{3}$

Step-by-step explanation:

Use the slope formula, $m = \frac{y_2-y_1}{x_2-x_1}$ , to find the slope. $m$ represents the slope. $x_1$ and $y_1$ represent the x and y values of one point, and $x_2$ and $y_2$ represent the x and y values of another point. So, substitute the x and y values of the points (-3, 4) and (0, 0) into the formula appropriately and solve:

$m= \frac{(0)-(4)}{(0)-(-3)} \\m = \frac{0-4}{0+3} \\m = \frac{-4}{3}$

Thus, the slope is $-\frac{4}{3}$ .

Write the quadratic equation whose roots are 3 and 1, and whose leading coefficient is 1

Serhud [2]

Answer:

x² - 4x + 3 = 0

Step-by-step explanation:

given roots x = a and x = b then the corresponding factors are

(x - a) and (x - b)

the equation is then the product of these factors , that is

(x - a)(x - b) = 0

given

roots x = 3 and x = 1 , then factors are (x - 3) and (x - 1) , then

(x - 3)(x - 1) = 0 ← expand factors using FOIL

x² - 4x + 3 = 0

Write the equation of a line that is parallel to y=0.6x+3 and that passes through the point

a_sh-v [17]

A line parallel to y = 0.6x + 3 will be of the form:

$y = 0.6x + k$

where k is a constant.

It passes through (-3,-5)

Thus,

$y = 0.6x + k \\ \\ -5 = 0.6 \times (-3) + k \\ \\ -5 = -1.8 + k \\ \\k = -5 + 1.8 \\ \\ k = -3.2$

$\textbf{The equation is \: \: y = 0.6x - 3.2}$
