Answer:
3, 8, 14, 30, 58
Step-by-step explanation:
As with all formulas, put the numbers in place of the corresponding variables, and do the arithmetic.
The first 5 terms of the sequence are 3, 8, 14, 30, 58.
Answer:
y = -1/2x - 7
Step-by-step explanation:
y2 - y1 / x2 - x1
-6 - (-5) / -2 - (-4)
-1 / 2
= -1/2
y = -1/2x + b
-5 = -1/2(-4) + b
-5 = 2 + b
-7 = b
Answer:
f(-4) = 72, f(x + 5) = 3x² + 23x + 36
Step-by-step explanation:
f(-4) = 3(-4)² - 7(-4) - 4
= 48 - (-28) - 4
f(-4) = 72
f(x + 5) = 3(x + 5)² - 7(x + 5) - 4
= 3(x + 5)(x + 5) - 7(x + 5) - 4
= 3(x² + 10x + 25) - 7(x + 5) - 4
= 3x² + 30x + 75 - 7x - 35 - 4
f(x + 5) = 3x² + 23x + 36

Answer:
The area of the circle is 19.625.
Step-by-step explanation:
- To find the area of a circle, you use the formula A=πr², so you need the radius. The radius is half of the diameter, so half of 5 is 2.5.
- Next, you just plug the numbers into the formula (I used 3.14 for pi). A=(3.14)(2.5²).
- A=(3.14)(6.25)
- A=19.625
- Round to your liking/whatever the question asks for and add the units the question asks for as well. If there aren't any offered in the question, just use units squared if you have to give any.
