The triangles are congruent. The theorem that proves this is SAS, which stands for side and side. As seen in the picture the red marks indicate that these triangles have two congruent sides. And from how they’re connected at the angles, we also see they have congruent angles. Therefore the answer is SAS Theorem.

You buy x bottles of soda for $1.50 using a gift card that you got as a reward for getting good grades

nadya68 [22]

Answer:

$0\leq x \leq 10$

Step-by-step explanation:

The function is $f(x)=15-1.50x$ where x is the number of bottles of soda.

The domain means the set of "allowed" x values.

Also, f(x) means the amount of money left, which cannot be less than 0. So we put 0 into f(x) and solve for x:

$f(x)=15-1.5x\\0=15-1.5x\\1.5x=15\\x=\frac{15}{1.50}\\x=10$

This means the highest number of bottles you can buy is 10. So the domain is anything from 0 to 10. <em>You can buy 0 until highest 10 bottles. Hence the domain is </em>

$0\leq x \leq 10$

The function h(t) = -4.9t² + 19.6t is used to model the height of an object projected in the air where h(t) is the height (in me

goblinko [34]

Answer:

Step-by-step explanation:

when h(t)=0

-4.9 t²+19.6t=0

4.9t(-t+4)=0

either t=0 or t=4

so domain is 0≤t≤4

for range

h(t)=-4.9t²+19.6t

=-4.9(t²-4t+4-4)

=-4.9(t-2)²+19.6

so range is 0≤h≤19.6
