The graph shows the height, y, of a diver x seconds after she jumps from a 25 meter diving platform. At what approximate value of x seconds is the diver's maximum height reached?
HAVE A GOOD DAYYY!!!
Answer: x=1
Step-by-step explanation: I verified it , it’s correct
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.

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.

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.

Find the diagonal of the box using the Pythagorean Theorem.
Answer:640^2
Step-by-step explanation:
The Pythagorean Theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse squared. You might recognize this theorem in the form of the Pythagorean equation: a 2 + b 2 = c 2.
8cm^2+24cm^2=640^2
the radius of a well is 1.4m and its depth 35 m is half-filled with water. find the volume of water inside the drum.
Detailed and explanatory answer, to get marked brainly (should be correct too)
Answer:
≈ 108 m³
Step-by-step explanation:
You're searching for the volume of a cylinder. The formula needed to find it is V=πr²h.
In this case, the radius r is 1.4m and the height h is 35/2=17.5m, as it is only half filled.
Now when inserting values, you get: V=π*1.4²*17.5 which is 107.757 m³
9514 1404 393
Answer:
34.3π ≈107.8 m³
Step-by-step explanation:
There is no drum, only a well with water 35/2 = 17.5 m deep. The volume of water in the well is given by the formula for the volume of a cylinder:
V = πr²h
V = π(1.4 m)²(17.5 m) = 34.3π m³ ≈ 107.8 m³
_____
Additional comment
If you use 3.14 for π, the volume rounded to tenths is 107.7 m³. For an answer correct to 4 significant digits, I prefer a value of pi with more than 3 significant 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.

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
