Answer:

0.64

Step-by-step explanation:

9/14 is 0.642

rounding that decimal to the nearest hundredth would get you 0.64 because the 2 next to the 4 is below 5 so it would keep it the same.

The value of cos x°  is 8 divided by f

We will use trigonometrical ratios to solve this problem. Below are the definitions of the trigonometrical ratios:

sin = opposite/hypotenuse

cos = adjacent/hypotenuse

tan = opposite/adjacent or tan = sin/cos

The opposite is the side the angle of consideration is facing

The hypotenuse is the side the right angle  is facing

The adjacent is the side left after determining the opposite and hypotenuse

Given: tan x° = e/8 and sin x° = e/f

Since tan = opposite/adjacent, that means in tan x° = e/8, opposite = e and adjacent = 8. Also, sin = opposite/hypotenuse, so in sin x°= e/f, hypotenuse = f

And cos = adjacent/hypotenuse. Thus,  cos x° = 8/f.

Therefore, the value is cos x° = 8 divided by f is the answer. Pick the first option

Answer:

y = 7 + 2√2, y = 7 - 2√2

Step-by-step explanation:

We need to solve for y to find the solutions of the quadratic equation:

3(y-7)^2 = 24

(y-7)^2 = 8

y-7 = ±√8 = ±√(4*2) = ±2√2

y = 7 + 2√2

y = 7 - 2√2

2√2 is the simplified radical form because 4 is the highest factor of 8 that is a perfect square.

Answer: 20 hrs

Step-by-step explanation:

The values of the composite functions f(g(x)) and g(f(x)) are (x/4) and (4x - 9),respectively.

We are given two functions, f(x) and g(x). The function f(x) is defined as 1/(x - 3). The function g(x) is defined as (4/x) + 3. A function connects an input to an output. It is analogous to a machine with an input and an output. And the outcome is somehow connected to the input. We need to find the composition of the functions.

The first composition is f(g(x)). The composite function is solved below.

f(g(x)) = f((4/x) + 3)

f(g(x)) = 1/([(4/x) + 3] - 3)

f(g(x)) = 1/(4/x)

f(g(x)) = x/4

The second composition is g(f(x)). The composite function is solved below.

g(f(x)) = g(1/(x - 3))

g(f(x)) = (4/[1/(x - 3)]) + 3

g(f(x)) = 4(x - 3) + 3

g(f(x)) = 4x - 12 + 3

g(f(x)) = 4x - 9

No solution. This is because they do not cross.

The value of  L4 and R4 over [0,7] for the function f(x) = 6x² will be 2[2√0 + 2√2 + 2√4 + 2√6] and  2[2√2 + 2√4 + 2√6 + 2√8] respectively.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that the function is,

I'm assuming that you mean the left and right Riemann sums with four equal subintervals when you refer to L4 and R4.

If so, then Δx = (8-0)/4 = 2, and f(x) = 2√x.

L4 = f(0)Δx + f(2)Δx + f(4)Δx + f(6)Δx

L4 =2[2√0 + 2√2 + 2√4 + 2√6]

R4 = 2[2√2 + 2√4 + 2√6 + 2√8]

Thus, the value of  L4 and R4 over [0,7] for the function f(x) = 6x² will be 2[2√0 + 2√2 + 2√4 + 2√6] and  2[2√2 + 2√4 + 2√6 + 2√8] respectively.

Two angles A and B are supplementary when the value of x is 36°.

Two angles are said to be supplementary if their sum is 180°.

Two angles are said to be complementary if their sum is 90°.

Given, m∠A = (2x − 27)° and m∠B = (3x + 27)° are supplimentary to each other.

∴ (2x - 27)° + (3x + 27) = 180°.

2x + 3x - 27 + 27 = 180°.

The outsides, or O, would be: x*5 which equals 5x

The insides, or I, would be 7*x which equals 7x

The lasts, or L, would be 7*5 which equals 35

Department B     0.75      $45,000

The ratio is the proportion of the whole shared by two or more numbers.

Ratios are fractional values like proportions.

Ratios, depicted in fractions, decimals, and percentages, show how much a value or variable is contained in another.

Total distributable overhead = $60,000

Ratios = 10,000:30,000

= 1:3

Sum of Ratios = 4

OR

= 0.25:0.75

Sum of Ratios = 1

Department   Square Feet  Ratio    Amount of Overhead Allocated

Dept. A            10,000         A = 1      B = $15,000 ($60,000 x 0.25)

The image of  y = −2x^2 − 20x + 2 after a translation right 4 units and up 2 units is written in:

The graph will be a vertical parabola opening downwards

when the function y = −2x^2 − 20x + 2 translates right 4 units it gives  

y = -2(x - 4)^2 − 20(x - 4) + 2

going up two units

y = -2(x - 4)^2 − 20(x - 4) + 2 + 2

simplifying the equation further gives

y = -2(x - 4)(x - 4) − 20(x - 4) + 4

y = -2(x^2 - 8x + 16) - 20x - 80 + 4

y = -2x^2 + 16x - 20x - 32 - 80 + 4

y = -2x^2 - 4x - 108
