Help asap<br> missing work

lidiya [134]

Answer:

Step-by-step explanation:

In ΔLMK

short leg /long leg = 18/24

In ΔLMJ

short leg /long leg = 24/JK

Now we make them equal

(18/24) = (24/JK), cross multiply

18·JK = 24², divide both sides by 18

JK = 24²/18

JK = 32

The ratio of boys to girls in a class is 3:4. There are 35 students in the class. How many more girls than boys are there?

lisov135 [29]

Answer:

Step-by-step explanation:

sum the parts of the ratio, 3 + 4 = 7 parts

Divide the number of students by 7 to find the value of one part of the ratio

35 ÷ 7 = 5 ← value of 1 part of the ratio, then

3 parts 3 × 5 = 15 ← number of boys

4 parts = 4 × 5 = 20 ← number of girls

20 - 15 = 5

There are 5 more girls than boys

Which function matches g? Two hook shaped graphs, f and g, on a coordinate plane. The graph of f has three line segments: negati

avanturin [10]

Answer:

Option (2).

Step-by-step explanation:

Coordinates of points A(-2, 2), B(-1, -1), C(-1, 4) and (0, -2)

By using formula to get the length of any segment having extreme ends at $(x_1,y_1)$ and $(x_2,y_2)$ ,

d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Length of segment AB = $\sqrt{(-2+1)^2+(2+1)^2}$

= $\sqrt{10}$ ≈ 3.16

Length of segment CD = $\sqrt{(0+1)^2+(-2-4)^2}$

= $\sqrt{37}$ ≈ 6.08

Length of CD ≈ 2(length of AB)

But length of horizontal segments are equal.

Therefore, function 'f' is vertically stretched to form 'g'.

g(x) = 2f(x)

Now 'f' is translated by 1 unit right,

g(x) = 2f(x - 1)

Option (2) will be the answer.
