Answer:

Step-by-step explanation:

$0.70 per mile is the rate (slope), $10 flat fee is your starting cost (i.e. your y-intercept).

By slope - intercept linear equations we have:

(a) y=mx+b where m is the slope and b is the y-intercept.

y=0.70x+10

(b) The graph is linear on the coordinate plane because the slope (rate) is constant.

(c) The slope of this graph is $0.70 per mile and the y-intercept is $10 flat fee. Your cost is $10 initially and $0.70 for every mile driven.

Answer:

Step-by-step explanation:

Equation: y=0.70x + 10

It forms an increase in cost so the line slants upward.

Slope: The increase in miles per hour which is 0.70x

Intercept: Is the starting point on the y-intercept for which the line starts.Which is where the 10 comes in.(0, 10)

If a=mg-kv2/m,find,correct to the nearest whole number the value of v when a=2.8,m=12,g=9.8 and k=8/3

RUDIKE [14]

Answer:

The value of $v$ is ± 22.729.

Step-by-step explanation:

Let be $a=m\cdot g -\frac{k\cdot v^{2}}{m}$ , the variable $v$ is now cleared:

$\frac{k\cdot v^{2}}{m}=m\cdot g -a$

$k\cdot v^{2} = m^{2}\cdot g- m\cdot a$

$v^{2} = \frac{m^{2}\cdot g - m\cdot a}{k}$

$v =\pm \sqrt{\frac{m^{2}\cdot g-m\cdot a}{k} }$

If $a = 2.8$ , $m=12$ , $g = 9.8$ and $k = \frac{8}{3}$ , the value of $v$ is:

$v=\pm \sqrt{\frac{(12)^{2}\cdot (9.8)-(12)\cdot (2.8)}{\frac{8}{3} } }$

$v \approx \pm 22.729$

The value of $v$ is ± 22.729.

A parallelogram has an area of 36 square feet and two sides of lengths 6 feet and 9 feet. Which of the following is the sine of

Advocard [28]

<span>Area is base times height, so 9h = 36, h = 4
sine of base angle will be 4/6 = 2/3

So, the answer is A) 2/3

What is the answer too n+ 2 = -14-n ?

Irina18 [472]

Answer:

n = -8

Step-by-step explanation:

n + 2 = -14 - n

+n + n Add n to both sides

2n + 2 = -14

- 2 - 2 Subtract 2 from both sides

2n = -16 Divide both sides by 2

n = -8
