Answer:

ΔMNO= 90°, m = 7.316 cm, n = 16.69 cm

Step-by-step explanation:

The little square in the corner tells you that the angle is 90°

Calculating the length of m

We know that the Tangent of an angle is gotten by dividing the opposite side by the adjacent side, i.e,

Tan Ф = Opposite ÷ Adjacent

hence:

Tan 26° = m ÷ 15

0.4877 = m / 15

make m the subject and multiply both sides by 15

0.4877 × 15 = m / 15 × 15

7.3155 = m

∴ m = 7.316 cm

Calculating the length of n

For this we can use the Pythagoras theorem that states, a² + b² = c² where m = a, b = 15 cm and c = n. Hence:

7.316² + 15² = c ²

53.52 + 225 = c ²

278·52 = c ²

c = √278·52

c = 16.69

∴ n = 16.69 cm

We could also use the Cosine of ΔOMN to get length n i.e,

The Cosine of an angle is equal to the adjacent side divided by the hypotenuse.

Cosine Ф = Adjacent ÷ Hypotenuse

Cosine 26° = 15 cm ÷ n

0.8987 = 15 / n

Make 15 the subject and multiply both sides by n

0.8987 × n = 15 / n × n

0.8987 n = 15

Divide both sides by 0.8987

0.8987 n ÷ 0.8987 = 15 ÷ 0.8987

∴ n = 16.69 cm

Hope this helps!

4. Here are the equations that define three functions.

luda_lava [24]

The functions f(x), g(x) and h(x) are all linear functions

The function value that is largest is h(-100)
The function value that is largest is h(-100)
The function value that is largest is f(1/100)

<h3>How to determine the function with the largest values</h3>

The functions are given as:

$f(x) = 4x - 5$

$g(x) = 4(x - 5)$

$h(x) = x/4 -5$

At x = 100, we have:

$f(100) = 4 * 100 - 5 = 395$

$g(100) = 4 * (100 - 5) = 380$

$h(100) = 100/4 - 5 = 20$

Hence, the function value that is largest is f(100)

At x = -100, we have:

$f(-100) = -4 * 100 - 5 = -405$

$g(-100) = 4 * (-100 - 5) = -420$

$h(-100) = -100/4 - 5 = -30$

Hence, the function value that is largest is h(-100)

At x = 1/100, we have:

$f(1/100) = 4/100 - 5 = -4.96$

$g(1/100) = 4 * (1/100 - 5) = -19.96$

$h(1/100) = (1/100)/4 - 5 = -4.9975$

Hence, the function value that is largest is f(1/100)

A boat can travel 10 miles downstream in the same time it

AleksAgata [21]

Answer:

$\frac{10}{x+2} = \frac{3}{x-2}$

Step-by-step explanation:

The 10 represents the speed traveling downsteam while the 3 represents speed upstream. Downstream you have the help of the current, so it would be x + 2, upstream you are working against the current so it would be x - 2.
