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.

The most common form of color blindness is an inability to distinguish red from green. However, this particular form of color bl
MaRussiya [10]

Answer:

(a) P(CBM) = 0.07

(b) P(not CBW) = 0.996

(c ) P(neither is color-blind) = 0.926

(d) P=(at least one is color-blind) = 0.074

Step-by-step explanation:

The correct data is  that Approximately 7% of American men and 0.4% of American women are red-green color-blind.

(a) Probability that he is red-green color-blind:

P(CBM) = 0.07

(b) Probability that she is NOT red-green color-blind:

P(not\ CBW) =1- P(CBW)\\P(not\ CBW) = 1 -0.004\\P(not\ CBW) =0.996

(c) Probability that neither are red-green color-blind

P(neither) = P(not\ CBW)*P(not\ CBM) \\P(neither) = 0.996 *(1-0.07)\\P(neither)=0.926

(d) Probability that at least one of them is red-green color-blind

P(at\ least\ one) = 1- P(neither) \\P(at\ least\ one) = 1-0.926\\P(at\ least\ one) = 0.074

What is the Distance between (-4, -8) and (10, -8)??
katrin [286]

Answer:

The distance between both points would be 14.

Step-by-step explanation:

The y coordinate or -8 stays the same for both points on a coordinate grid. However the x coordinate changes from -4 to 10, which is 14 places away on a coordinate grid. Therefore the distance between these two points is 14.
