$\sf a = 2,\: b = 1$

$\sf Q) \:2a + 3b = {?}$

$\sf \implies 2a + 3b$

$\sf \implies 2(2) + 3(1)$

$\sf \implies 4 + 3$

$\sf \implies 7$ is the required answer.

Find the slope of a line that passes through the

Lubov Fominskaja [6]

Step-by-step explanation:

Hey there!

The given points are; (8,2) and (8,4).

Note: Use slope formula.

Now;

$slope(m) = (\frac{y2 -y 1}{x2 - x1})$

Keep all values.

$m = \frac{4 - 2}{8 - 8}$

Simplify it.

$m = \frac{2}{0}$

When we divide any number by "2" the result is undefined.

Therefore, the slope of the points is undefined.

Hope it helps...

Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirre

NeTakaya

Answer:

She caught 10 rabbits

Step-by-step explanation:

Given

Represent Rabbits with R; Squirrels with S and Deer with D

$S = 3D$

$S = R - 5$

$S + R+ D = 10 +4D$

Required

Determine the value of R

$S + R+ D = 10 +4D$

Solve for R

$R = 10 + 4D - D - S$

$R = 10 + 3D - S$

Recall that $S = 3D$

Substitute 3D for S

$R = 10 + 3D - 3D$

$R = 10$

Hence;

She caught 10 rabbits

Kari is flying a kite. She releases 50 feet of string. What is the approximate difference in the height of the kite when the str

MakcuM [25]

Answer:

Step-by-step explanation:

The string of a kite forms a right angle triangle with the ground. The length of the string represents the hypotenuse of the right angle triangle. The height of the kite represents the opposite side of the right angle triangle.

To determine the height of the kite, we would apply the sine trigonometric ratio which is expressed as

Sin θ = opposite side/hypotenuse.

1) if the kite makes an angle of 25° with the ground, then the height, h would be

Sin 25 = h/50

h = 50Sin25 = 50 × 0.4226

h = 21.1 feet

2) if the kite makes an angle of 45° with the ground, then the height, h would be

Sin 45 = h/50

h = 50Sin45 = 50 × 0.7071

h = 35.4 feet

The approximate difference in the height of the kite is

35.4 - 21.1 = 14.3 feet
