Answer:
h(0) = –16t^2 + 32t + 48
Step-by-step explanation:
If everything with a t is multiplied by zero, it will make everything 0 and leave the value of the constant, 48.
Answer:
x is 9
Step-by-step explanation:
since they are vertical angles, they are congruent. We make an equation putting each one behind the equal sign (7x+3=10x-24) and we solve.
Answer:
Step-by-step explanation:
It appears to be the last step there that has evaded you. In the second line of work, you can see that what's in each set of parenthesis is exactly the same. Because of this, it is common and can be factored out. What's left is the 4x and the +5:
(5x - 3)(4x + 5)
That's factoring by grouping. It only works with polynomials that have an even number of terms so you can group them together in 2's.
Short Answer B
Remark
The non adjacent angles add up to the given exterior angle.
Equation
The two non adjacent angles are equal and add up to the exterior angle.
Let one of the non adjacent interior angles = x
x + x = 140
2x = 140 Divide by 2
x = 140/2
x = 70
Comment
So the next step is to find the third angle
70 + 70 + x = 180 Combine like terms.
140 + x = 180 Subtract 140 from both sides.
x = 180 - 140
x = 40
Conclusion
The angles = 40 + 70 + 70
