Answer:
perimeter you add all sides together:
5x+2 +5x+2 +x +8 +x+8
12x +20
and for Area you multiply:
(x + 8)(5x + 2)
5x^2 + 2x + 40x +16
5x^2 +42x +16
so your answer is the first one or "A"

x=75
Step-by-step explanation:
The total degrees of a pentagon is 540
120+120+2(75)+75+75
120+120=240
2(75)=150
75+75=150
240+150+150=540
Consider the sequence 100, 95, 90, 85, 80, 75 ...
What is the value of f(8)?
Answers
Answer:
f(8) = 65
Step-by-step explanation:
Find a pattern in the sequence. It might be an arithmetic sequence (always adds or subtract by a certain number), or a geometric sequence (always multiplies or divides by a certain number).
To find a pattern in this decreasing sequence, we find either the common difference or the common divisor of each pair of consecutive numbers.
• 100 - 95 = 5
• 95 - 90 = 5
• 90 - 85 = 5
• 85 - 80 = 5
• 80 - 75 = 5
Now, we know that this is an arithmetic sequence, and the common difference is 5.
To calculate f(8), we find the 8th term in the sequence. We can do that by counting the terms in the sequence and using the common difference, 5, that we found, to continue the sequence.
• f(1) = 100
• f(2) = 95
• f(3) = 90
......
• f(7) = 70
• f(8) = 65

Step-by-step explanation
(-3,1) ___ -3 is x1 while 1 is y1
(-17, 2) ___ -17 is x2 while 2 is y2
slope formula is m = y2-y1/x2-x1
plug them in: m = 2-1/-17-(-3), which equals 1/-14 or -0.071428571428571
If a= 5^99 x 2^98 and b= 5^72 x 4^38 show ab has 172 digits when written as a ordinary number
This is a proof question. Please show step by step.
Answers
Step-by-step explanation:
ab
= (5⁹⁹ * 2⁹⁸) * (5⁷² * 4³⁸)
= 2⁹⁸ * 2⁷⁶ * 5⁹⁹ * 5⁷²
= 2¹⁷⁴ * 5¹⁷¹
= 2³ * (2¹⁷¹ * 5¹⁷¹).
The 2¹⁷¹ * 5¹⁷¹ will give 171 ending zeroes as 2 * 5 = 10.
And there is a 8 infront as 2³ = 8.
Hence altogether there are 171 + 1 = 172 digits.

Step-by-step explanation:
A baseball is thrown in parabolic arc its position above the ground at a given point in time can be represented by a quadratic function p(t)= 1/2gt^2 + v0t +p0 where t > 0, g is -32ft/sec/sec, V0 is additionally velocity and P0 SH initial position above the ground. If the ball is thrown straight up 16ft/sec when it was 5ft above the ground how high did it go
Answers
Answer:
13 ft.
Step-by-step explanation:
Since p(t)= 1/2gt² + v₀t +p₀ and it us given that v₀ = 16 ft/s, p₀ = 5 ft and g = -32 ft/s².
Since the ball is thrown straight up, it does not follow a parabolic path.
So, If the ball is thrown straight up 16ft/sec when it was 5ft above the ground, then its height above the ground h(t) = v₀t +p₀. Substituting v₀ = 16 ft/s, p₀ = 5 ft , we have
h(t) = v₀t +p₀
Using v = v₀ + at, we calculate the time it takes to reach maximum height. At maximum height, v = 0, so,
v = v₀ + at
v - v₀ = at
t = (v - v₀)/a where a = g
So, t = (0 - 16 ft/s)/-32 ft/s²
= - 16 ft/s/-32 ft/s²
= 1/2 s
= 0.5 s
Substituting t = 0.5 s, v₀ = 16 ft/s and p₀ = 5 ft into h(t), we have
h(t) = v₀t +p₀
h(t) = 16 ft/s × 0.5 s + 5 ft
h(t) = 8 ft + 5 ft
h(t )= 13 ft
The ball will go 13 ft above the ground.

How many miles does Imelda jog on all 7 days combined?
Answers
Answer: 22.6875 miles
Step-by-step explanation:
Monday = 2 3/4 miles = 2.75 miles
Tuesday = 2.75 miles
Wednesday = 2.75 miles
Thursday = 2.75 miles
Friday = 2.75 miles
Saturday = 2.5 × 2.75 = 6.875 miles
Sunday = 0.75 × 2.75 = 2.0625 miles
Total = 2.75 miles + 2.75 miles + 2.75 miles + 2.75 miles + 2.75 miles + 6.875 miles + 2.0625 miles
Total = 22.6875 miles
