Doubling the linear dimensions (side lengths) of any figure doubles its perimeter and quadruples (x 4) its area. If its a 3-D (solid) figure, its volume multiplies by 8 .

Let f(x) = 5x3 + 3x2 – 3 and g(x) = x2 + X - 5, fin<br> 4) f(x) + g(x)
aleksley [76]

Answer:

f(x)+g(x)=5x^{3} +4x^{2}+x-8

Step-by-step explanation:

Given:

Two functions are given:

f(x)=5x^{3} +3x^{2} -3

g(x)=x^{2} +x-5

Find f(x)+g(x)

Solution:

f(x)+g(x)=(5x^{3} +3x^{2} -3)+(x^{2} +x-5)

f(x)+g(x)=5x^{3} +3x^{2} -3+x^{2} +x-5

f(x)+g(x)=5x^{3} +(3x^{2} +x^{2})+x-3-5

f(x)+g(x)=5x^{3} +4x^{2}+x-8

Therefore, the function of f(x)+g(x)=5x^{3} +4x^{2}+x-8

How you do multiply complex numbers ? Example : (9 - 4i) (8 + 6i)
Andrew [12]

You multiply them just as you would multiply any normal polynomials, except there is a special rule. Since we know that i = √-1, the rule is that i² = -1. So, let's multiply:

(9-4i)(8+6i) = 72+54i-32i-24i^2

Let's simplify this:

72+22i+(-24*-1)

72+22i+24 = 96+22i

Therefore, your answer is 96 + 22i.

BRCA1 is a gene that has been linked to breast cancer. Researches at Stanford University wanted to estimate what proportion of w
Evgesh-ka [11]

Answer:

The point estimate for the proportion of women with BRCA1 mutation is 0.168

Step-by-step explanation:

The point estimate for the proportion of women with BRCA1 mutation is the number of women with this mutation divided by the size of the sample.

Of the 173, they found that 29 had BRCA1 mutations.

29/173 = 0.168

The point estimate for the proportion of women with BRCA1 mutation is 0.168
