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.
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.

Which weighs more: a watermelon that weighs 7.5 kilograms or a baby that weighs 12 pounds? Note: 1 pound is about 0.45 kilograms.
Answer:
The baby weighs less then the watermelon.
Step-by-step explanation:
The 12 pounds of the baby = about 5.4 kilograms unlike the 7.5 kilograms of the watermelon.
The 12 pounds of the baby = about 5.4 kilograms unlike the 7.5 kilograms of the watermelon. the baby weighs less than the watermelon.

What is the slope of a line that is parallel to the graph of the equation y = 10x - 20?
Answer:
y parallel =10 or 10
Step-by-step explanation:
(-3, 1), (-17, 2) find the slope show the work
Answer:
1/-14 or -0.071428571428571
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
Consider the sequence 100, 95, 90, 85, 80, 75 ...
What is the value of f(8)?
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:
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
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.

The diver's greatest height is attained at 1 second.
What is a projectile motion?Projectile motion is the type of motion an object experiences when it is launched into the air and accelerates due to gravity. The item is the projectile, and the projectile's trajectory is its course.
Provided that the height of a diver, y, is shown on the graph x seconds after she falls off a 25-meter diving platform.
According to the provided graph, the diver's maximum height is 30 meters, and he will reach it in 1 second.

Imelda jogs 2 3/4 miles each weekday, Monday through Friday. On Saturday, she logs 2.5 times the daily weekday distance. On Sunday she jogs 3/4 of the daily weekday distance.
How many miles does Imelda jog on all 7 days combined?
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
