Answer:

Step-by-step explanation:

If the number ends in 0 or 5 those are the only two results that 5 will divide into a number evenly.

For example 105/5 = 21

And example 1020/5 = 204

So if you want a remainder of 2, there are 2 ways to get it.

1) If the number ends in a two, you will get a remainder of 2. That's because 0 + 2 will give 2.

For example 252 / 5 = 50 with a remainder of 2

2) The other way is if the end number is 7.

3347 / 5 = 669 with a remainder of 2.

The reason this works is if you subtract 2 from the number given then the units digit will be either 0 or 5. Those two endings result in even division.

Use limits to find the area of the region bounded by the graph f(x)=4-2x^3 , the x-axis , and the vertical lines x=0 and x=1

gtnhenbr [62]

Answer:

$\frac{7}{2}$ square units.

Step-by-step explanation:

We have to use limits to find the area of the region bounded by the graph $f(x) = 4 - 2x^{3}$ , the x-axis, and the vertical lines x=0 and x=1.

So, the area will be

A = $\int\limits^1_0 {(4 - 2x^{3})} \, dx$

= $[4x - \frac{x^{4}}{2} ]^{1} _{0}$

= $4 - \frac{1}{2}$

= $\frac{7}{2}$ square units. (Answer)

A semicircle has the radius of 2 4/5. What is its area? leave your answers in term of π

Ratling [72]

Answer:

$11\dfrac{13}{25}\pi$

Step-by-step explanation:

r = Radius of semicircle = $2\dfrac{4}{5}=\dfrac{24}{5}\ \text{units}$

Area of semicircle is given by

$A=\dfrac{\pi r^2}{2}\\\Rightarrow A=\dfrac{\pi \left(\dfrac{24}{5}\right)^2}{2}\\\Rightarrow A=\dfrac{288}{25}\pi=11\dfrac{13}{25}\pi\ \text{sq. units}$

The area of the semicircle is $11\dfrac{13}{25}\pi\ \text{sq. units}$ .

GUYS HELP ME PLS. Tina is standing at the bottom of a hill. Matt is standing on the hill so that when Tina's line of sight is

Pie

Answer:

71°

Step-by-step explanation:

The angle of elevation of the hill can be obtiaed using trigonometry :

Given

the opposite length = 14.5 feets

Adjacent = 5 feets

The angle of elevation vabnbe obtained using :

Tan θ = opposite / Adjacent

Where θ = angle of elevation

Tan θ = 14.5 / 5

Tan θ = 2.9

θ = tan^-1(2.9)

θ = 70.97 = 71°

Please help me, I have no idea what the equation for the new path is. <br><br> Thank you!!

Citrus2011 [14]

First, find the slope of the initial line;

m=(y₁-y₂)/(x₁-x₂)

m=(4-0)/(11-8)
m=4/3

If two lines are parallel, the slope is the same although the intercept can differ.

If this parallel lines passes through the point (4, 5);

y=(4/3)x+c <-- plug in coordinates to solve for c
5=(4/3)(4)+c
(15/3)=16/3+c
(15/3)-(16/3)=c
-1/3=c

Therefore, the final equation should be y=4/3x-1/3

Hope I Helped :)
