Step-by-step explanation:

That function is a line that goes through the origin (0,0).

You only need one more point to be able to draw it.

Take x=4,5 the corresponding value of y is exactly what you want to know, the number of miles the lava moved after 4,5 hours.

So y = 6 * 4,5 = 27

Your second point is (4,5 , 27).

Now you can draw your line.

If you shift the quadratic parent function, f(x) = x^2, right 10 units, what is the equation of the new function?

jenyasd209 [6]

If you shift function f(x) a units right you'll get f(x-a) function.

So if you have f(x) = x², you'll get f(x-10) = (x-10)² - answer B

other formulas:

a units left: f(x+a)

a units up: f(x)+a

a units down: f(x)-a

First determine the missing angle for triangle 1 and triangle 2. Then apply the angle-angle criterion to determine if the two tr

barxatty [35]

Answer:

Triangle 1 – ∠1 = 25°, ∠2 = 115° Triangle 2 – ∠1 = 25°, ∠3 = 40°
Triangle 1 – ∠1 = 5°, ∠2 = 15° Triangle 2 – ∠2 = 15°, ∠3 = 160°

Step-by-step explanation:

You can save yourself some trouble if you realize that one of the angles in one pair must match one of the angles in the other pair.

This observation eliminates the first two choices.

Going further, the triangles will be similar if the dissimilar angles together with one of the similar angles totals 180°.

Triangle 1 – ∠1 = 50°, ∠2 = 30°

Triangle 2 – ∠2 = 20°, ∠3 = 100° . . . . . no angles match

Triangle 1 – ∠1 = 60°, ∠2 = 20°

Triangle 2 – ∠1 = 40°, ∠3 = 100° . . . . . no angles match

Triangle 1 – ∠1 = 25°, ∠2 = 115°

Triangle 2 – ∠1 = 25°, ∠3 = 40° . . . . 25° angles match; 25+40+115 = 180

These triangles are similar.

Triangle 1 – ∠1 = 5°, ∠2 = 15°

Triangle 2 – ∠2 = 15°, ∠3 = 160° . . . . 15° angles match; 15+5+160 = 180

These triangles are similar.

The average price (in dollars) to rent a studio in a certain city can be approximated by the equation p=28.2t+644 where t is the

egoroff_w [7]

$p = 28.2t + 644\\\\p-644 = 28.2t\\\\\frac{p-644}{28.2} = \frac{28.2t}{28.2}\\ \\t = \frac{p-644}{28.2}$

$t = \frac{1320.80-644}{28.2} \\\\t = 24$

It will take 24 years.
