f(x) = x +4
g(x) = 3x^2 – 7
Find (f.g)(x)

Answers

Answer 1

Answer:

(f*g)(x) = 3x³+12x²-7x-28

Step-by-step explanation:

What (f*g)(x) means is that we multiply f(x) by g(x):

f(x) = x+4

g(x) = 3x²-7

(f*g)(x) = f(x)*g(x) = (x+4)(3x²-7) = (x)(3x²)+(x)(-7)+(4)(3x²)+(4)(-7) = 3x³-7x+12x²-28 = 3x³+12x²-7x-28

Answers

Answer:  H = {3, 5, 7}

Explanation:

We simply list any odd number that is between 2 and 8. The term "roster form" can be thought of as listing the roster of a sports team (eg: baseball). So instead of describing what the numbers look like, we list out the numbers themselves. Those numbers being 3, 5 and 7.

Something like {2,4,6,8} is ruled out because we're dealing with odd numbers only.

Step-by-step explanation:

(3x³)⁴ can be simplified into (3x)¹²

The simplified value of the given expression is 3x¹²

What is simplification?

Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler, usually shorter.

Given that, an expression (3x³)⁴

Using the identity = (xᵃ)ᵇ = xᵃᵇ

(3x³)⁴ = (3x)³ˣ⁴ = 3x¹²

Hence, the simplified value of the given expression is 3x¹²

The length of TU in the right triangle is  156.15 m.

The area of the rectangle is 12335.85 m²

The length of GH in the right triangle is 182.33 m

The area of the triangle is 8934.17 m²

Right angle triangle

Right angle triangle are triangle that has one of its angle as 90 degrees. The sides of the triangle can be found using Pythagoras theorem. Therefore, using Pythagoras theorem,

TU² = 175² - 79²

TU² = 30625 - 6241

TU² = 24384

TU = √24384

TU = 156.153770368

TU = 156.15 m

area of rectangle = lw

area of rectangle =  156.15 × 79

area of rectangle =  12335.85 m²

GH² = 207² - 98²

GH² = 42849 - 9604

GH² = 33245

GH = √33245

GH = 182.33211456

GH = 182.33 m

Area of the triangle = 1 /  2 bh

Area of the triangle = 1 /  2 × 98 × 182.33

Area of the triangle = 17868.34 / 2

Area of the triangle = 8934.17 m²

What is confidence interval for population proportion?

Formula to calculate the confidence interval for population proportion p :-

[tex]p' - Z_{\alpha }\sqrt{\frac{p'q'}{n} } < p < p' + Z_{\alpha }\sqrt{\frac{p'q'}{n} }[/tex]

Where,

p is the population proportion.

p' is the sample proportion.

n is the size of the sample.

[tex]Z_{\alpha }[/tex] is the desired degree of confidence.

Given that a 98% confidence interval for a proportion p is found to be (0.62, 0.68).

[tex]p' - Z_{\alpha }\sqrt{\frac{p'q'}{n} } = 0.62\\\\p' + Z_{\alpha }\sqrt{\frac{p'q'}{n} } = 0.68[/tex]
