Sanjay graphs a quadratic function that has x-intercepts of –3 and 7. Which functions could he have graphed? Check all that appl
dem82 [27]
1,3,and 4 because for 1 and 3 if you factor it out you can get (x+3)(x-7) which if you solve it it creates them to be -3 and 7. The 4 one is already factored you just solve it and it also becomes -3 and 7. The - outside the parentheses is nothing.

In triangle ABC find b to the nearest degree given a=7 b=10 and c is a right triangle
eimsori [14]

Answer:

∠B =55.00797173^{\circ}

Step-by-step explanation:

Given : a=7 b=10 and C is a right triangle

solution :

refer the attached figure .

Since ΔACB is right angled triangle so we will use trigonometric ratios .

tan\theta=\frac{perpendicular}{base}

Perpendicular = b =10

Base=a=7

Putting value in formula:

tanB=\frac{10}{7}

tanB=1.42857

B=tan^{-1}1.42857

B=55.00797173^{\circ}

Thus ∠B =55.00797173^{\circ}

Tatiana [17]

If a $24 dvd is marked down by 30% then the cost of the dvd would be 70% of the original cost. 100% - 30% = 70%

70% of 24 can be expressed as 0.7 x 24.

The answer is $16.80.
