Answer:

∠ A ≈ 35.54°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan A = $\frac{opposite}{adjacent}$ = $\frac{BC}{AC}$ = $\frac{5}{7}$ , thus

A = $tan^{-1}$ ( $\frac{5}{7}$ ) ≈ 35.54° ( to the nearest hundredth )

Well there are 5280 feet in 1 mile and if you multiply that by 2 then that's too many. if you multiply 5280 by 1.5, then you get 7920 so it is equal to 1.5 miles.

There are 36 inches in 1 yard so you multiply 6 by 36 to get 216.

Again there are 5,280 feet in 1 mile. Divide 26,400 by 5,280 and you get 50 miles.

12 inches in 1 foot. Multiply 12 by 9 and get 144.

22 feet equals 7 yards and 1 foot.

51 inches equals 4 feet and 3 inches. (4 feet equals 48 inches)

Btw, 7 yards is greater then 20 feet (7 yards equals 21 feet)

2 miles is more then 3,500 yards. (2 miles equals 2,520 yards)

11.5 feet is less then 4 yards (4 yards equals 12 feet)

72 inches is EQUAL to 2 yards

5.5 yards is more then 192 inches. (5.5 yards equals 198 inches)

121.77984k

Step-by-step explanation:

a) Scale = k9.52*3 = 28.56/linear yard

b) Scale = k9.52*3.28 = 32.2256/linear meter

c) Cost = 3.9 * 32.2256 = 121.77984k

If f(x)=x^3-12x^2+35x-24f(x)=x 3 −12x 2 +35x−24 and f(8)=0f(8)=0, then find all of the zeros of f(x)f(x) algebraically.

Neporo4naja [7]

Answer:

The zeros of f(x) are: (x - 1), (x - 3) and (x - 8)

Step-by-step explanation:

Given

$f(x)=x^3-12x^2+35x-24$

$f(8) = 0$

Required

Find all zeros of the f(x)

If $f(8) = 0$ then:

$x = 8$

And $x - 8$ is a factor

Divide f(x) by x - 8

$\frac{f(x)}{x - 8} = \frac{x^3-12x^2+35x-24}{x - 8}$

Expand the numerator

$\frac{f(x)}{x - 8} = \frac{x^3 - 4x^2 -8x^2 + 3x + 32x - 24}{x - 8}$

Rewrite as:

$\frac{f(x)}{x - 8} = \frac{x^3 - 4x^2 + 3x - 8x^2 +32x - 24}{x - 8}$

Factorize

$\frac{f(x)}{x - 8} = \frac{(x^2 - 4x + 3)(x - 8)}{x - 8}$

Expand

$\frac{f(x)}{x - 8} = \frac{(x^2 -x - 3x + 3)(x - 8)}{x - 8}$

Factorize

$\frac{f(x)}{x - 8} = \frac{(x - 1)(x - 3)(x - 8)}{x - 8}$

$\frac{f(x)}{x - 8} = (x - 1)(x - 3)$

Multiply both sides by x - 8

$f(x) = (x - 1)(x - 3)(x - 8)$

<em>Hence, the zeros of f(x) are: (x - 1), (x - 3) and (x - 8)</em>
