Simplify completely the quantity 5 times x to the third power plus 10 times x to the 2nd power plus 15 times x all over 5 times
dedylja [7]
The <u>correct answer </u>is:

x²+2x+3.

Explanation:

\frac{5x^3+10x^2+15x}{5x}

We need to divide each term of the numerator by the denominator.  For the <u>first term</u>:
\frac{5x^3}{5x}

Dividing the coefficients, we have 5/5 = 1.  
When dividing the variables, we use the quotient rule:  when dividing powers that have the same base, subtract the exponents.  This gives us:
x³/x = x³/x¹ = x³⁻¹ = x²

For the first monomial, this gives us 1x² = x².

The <u>second term</u>:
\frac{10x^2}{5x}

Dividing the coefficients, we have 10/5 = 2.
Dividing the variables, we again use the product rule:
x²/x = x²/x¹ = x²⁻¹ = x¹ = x

Together this gives us 2x.

The <u>third term</u>:
\frac{15x}{5x}

Dividing the coefficients, we have
15/5 = 3.
Dividing the variables, we have x/x; when you divide something by itself, the answer is 1.  This gives us:
3*1 = 3.

Together our quotient is x²+2x+3.

Kuzi and Joanne live 130 km apart. They start travelling towards each other at the same time. If Kuzi covers 16 km every 2 hours
Zepler [3.9K]

Using the speed - distance relationship, the distance traveled by Joanne would be 55.714 km

Kuzi's speed :

  • <em>16</em><em>/</em><em>2</em><em> </em><em>=</em><em> </em><em>8km</em><em> </em><em>/</em><em> </em><em>hr</em><em> </em>

Joanne's speed :

  • <em>6km</em><em>/</em><em>hr</em><em> </em>

Let time taken = <em>t</em>

<u>Total</u><u> </u><u>distance</u><u> </u><u>traveled</u><u> </u><u>:</u>

8t + 6t = 130

14t = 130

t = 130/14

t = 9.2857142 hours

<u>Therefore, distance traveled by Joanne</u> :

Joanne's speed × time

6 km × 9.2857142 = 55.714 km

Therefore, distance traveled by Joanne will be 55.714 km

A cylinder has a volume of 8792 cubic units. If the height is 7 cubic u it’s which of the following is the radius
natima [27]

Answer:

20 units

Step-by-step explanation:

Volume of a cylinder = πr²h

V = πr²h

height, h = 7

V = π * r² * 7

V = 8792

8792 = 21.991148 * r²

r² = 8792 / 21.991148

r² = 399.79722

r = √399.79722

r = 19.99unit

r = 20 units
