Answer:

in fraction form: -1/36, 1/216, -1/1296

in decimal form: -.03, .005, -.0008

Step-by-step explanation:

Each term is the previous term divided by -6:

-36 ÷ -6= 6

6 ÷ -6= -1

and so on...

You provide a dog-walking service, and you report to the owners on the amount of exercise their dogs get on the walks. You walke

Neporo4naja [7]

Answer:

D. $2\frac{4}{7}\text{ mph}$

Step by step explanation:

First of all we will convert our given time from minutes to hour by dividing 35 by 60.

$35 \text{ minutes}=\frac{35}{60} \text{ hours}$

Let us find speed of dog during walk.

$\text{Speed of dog}=1.5 \div \frac{35}{60}$

Dividing a number by a fraction is same as multiplying the number by the reciprocal of the fraction.

$\text{Speed of dog}=1.5\times \frac{60}{35}$

$\text{Speed of dog}=\frac{1.5\times 60}{35}$

$\text{Speed of dog}=\frac{90}{35}$

$\text{Speed of dog}=\frac{18}{7}$

$\text{Speed of dog}=2\frac{4}{7}$

Therefore, speed of dog is $2\frac{4}{7}\text{ mph}$ and option D is the correct choice.

Can you find the PERIMETER of this shape pls

Katena32 [7]

Answer:

25.7 m

Step-by-step explanation:

Hello!

We have two sides each measuring 5m, so the length of the straight edges is 2(5m) or 10m

We also have two identical semi-circle circumferences, so if we find the circumference of the whole circle, we can find the total length of the curved edges.

C = 2πr
C = 2(3.14)(2.5)
C = 5(3.14)
C = 15.7

Now, we can add up the two lengths:

Perimeter = straight sides + curved sides
Perimeter = 10m + 15.7m
Perimeter = 25.7m

The polynomial function f(x) = 3x5 – 2x2 + 7x models the motion of a roller coaster. The roots of the function represent when th

cupoosta [38]

Answer:

$x=0$

Step-by-step explanation:

We have been given that a polynomial function $f(x)=3x^{5}-2x^{2}+7x$ models the motion of a roller coaster. Every root of the polynomial represent when the roller coaster is at the ground level.

In order to find all the potential values of x when roller coaster is at the ground level, we find the zeroes of the polynomial by factoring it as shown below:

$f(x)=3x^{5}-2x^{2}+7x\\f(x)=x(3x^{4}-2x+7)\\$

The zeroes of this polynomial occur when either $x=0$ or $3x^{4}-2x+7=0$ .

The equation $3x^{4}-2x+7=0$ have no real solutions. Therefore, the only time when the roller coaster is at the ground is at $x=0$
