Divide 132kg in a ratio of 3:3:5
skad [1K]
You have to add 3+3+5.
It equals 11.
Then divide 132 by 11.
It equals 12.
Then you have to put it into the ratio, so you multiply each number by 12.
So the ratio is 36:36:60

The function A(b) relates the area of a trapezoid with a given height of 14 and one base length of 5 with the length of its othe
Brut [27]

Answer:

b(a) =\frac{a}{7} -5

Step-by-step explanation:

Given

A(b) = 14 * \frac{b + 5}{2}

Required

Determine the inverse function b(a)

Write A(b) as a

a = 14 * \frac{b + 5}{2}

Swap a and b

b = 14 * \frac{a + 5}{2}

b = 7(a + 5)

Divide both sides by 7

a + 5 = \frac{b}{7}

Maka a the subject

a =\frac{b}{7} -5

Swap a and b again

b =\frac{a}{7} -5

Hence:

b(a) =\frac{a}{7} -5

. Find the value of sec θ for the angle shown. (2 points) A line is drawn from the origin through the point seven comma six. The
choli [55]

Answer:  \frac{\sqrt{85}}{7}

<u>Step-by-step explanation:</u>

(7, 6)

Use Pythagorean Theorem to find the hypotenuse:

7² + 6² = c²

49 + 36 = c²

   85      = c²

   √85  = c

adjacent = 7, opposite = 6, hypotenuse = √85

sec θ = \frac{hypotenuse}{adjacent} = \frac{\sqrt{85}}{7}

The reciprocal parent function is translated 5 units right and 3 units up. Write an equation to represent the new function.
ladessa [460]

Answer:

The new function is y=\frac{1}{x-5}+3 , where x ≠ 5

Step-by-step explanation:

The reciprocal parent function is f(x)=\frac{1}{x} , where x ≠ 0

The translation of f(x) to the right h units is f(x - h)

The translation of f(x) up k units is f(x) + k

The translation of f(x) to the right h units and up k units is f(x - h) + k

∵ The equation of the reciprocal parent function is  y=\frac{1}{x}

∵ The function is translated 5 units right

∴ h = 5

- That means 5 is subtracted from x ⇒ (x - 5)

∵ The function is  translated 3 units up

∴ k = 3

- That means y added by 3

∴ y=\frac{1}{x-5}+3

The new function is  y=\frac{1}{x-5}+3 , where x ≠ 5
