A ball is kicked upward with an initial velocity of 56 feet per second. The ball's height h (in feet) can be expressed as a function of time t (in seconds) by the equation h = -16t2 + 56t. How much time does the ball take to reach its highest point?
1.75 seconds B) 2.50 seconds C) 2.75 seconds D) 3.50 seconds
Answer:
1.75
Step-by-step explanation:
h(t) = -16t² + 56t
h'(t) = -32t + 56
To find time at max height equate h' to 0
0 = -32t + 56
t = 56/32 = 1.75 s
It takes 1.75 s to reach max highest point
hiii need help again thank youuu:)
Answer:
678.58 ft^3
Step-by-step explanation:
V=πr2h/3
25.12/12.5663706 = 1.99898608
1.99898608 X 3 = 5.99695826
h= 6ft
6/2 = 3
6 * 3 = 18
V = π * 6^ * 18/3
V = 678.584013

Find the measure of arc FV
Answer:
FV = 60
Step-by-step explanation:
VG => 65 × 2 = 130
FH major arc=> 119 × 2 = 238
FH major arc - GH = FG
FG => 238 - 168 = 70
VG - FG major arc = FV
FV => 130 - 70 = 60
Answer:
60 degrees
Step-by-step explanation:
The measure of an inscirbed angle is half the measure of the intercepted arc.
(The measure of the arc is twice the measure of the angle!)
The inscribed angle at V intercepts an arc of 2 x 119 = 238 degrees, so the measure of arc FGH is 238. Subtract arc GH from that, 238 - 168 = 70, so that is the measure of arc FG.
The angle at H intercepts an arc with measure 2 x 65 = 130. The measure of arc VFG is 130. But arc FG is part of that, so subtract its measure from 130. 130 - 70 = 60.
The measure of arc FV is 60 degrees.

Answer:
No, this is not a function. If you place the points, it will not pass the vertical line test. And, in a function, each x-coordinate has to have one y-coordinate. In this problem, there are two x-coordinates of 3, and they both have a different y-coordinate.

plug in the day to the equation:
November 1st is day 305, so November 24th would be day 328
y = 116.65 sin(0.02(328) +1.89) + 731.71
= 116.65 sin(8.45) + 731.71
= 828.247 minutes of daylight
≈ 13.8 hours or 13:48 (because .8 of an hour is ≈ 48 minutes)
Ja’quan was told to go inside one afternoon while he was at summer camp. He heard thunder and saw flashes of lightning. Suddenly, small balls and chunks of ice were falling on the field. Ja’quan checked the thermometer, because he never saw ice fall in South Florida, and noticed that it was 77°F (or 25°C). How was ice able to fall even though the temperature was much warmer than freezing? a) Ja’quan read the thermometer wrong b) He must have observed hail falling from thunder clouds c) It was cold enough to allow solid precipitation to fall d) Children were most likely throwing ice Reasoning (explain your answer using science facts) _________________________________________ _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Answer:
b
Step-by-step explanation:
hail can occur at temperatures not too cold and not too hot. since he checked his thermometer and it was warm, it is certainly possible that he saw hail

5 divided by 3 1/3, by lowest point
Answer:
1.42
Step-by-step explanation:
Answer:
1 1/2
Step-by-step explanation:
Step 1: convert 3 1/3 to improper fraction. Use thus rule a b/c=ac+b/c. 5 divided by 3x3x+1/3
step 2: simplify 3x3 to 9 5 divided by 9+1/3
Step 3: simplify 9+1 to 10. 5 divided by 10/3
Step 4: use the rule a divided by b/c=axc/b 5x3/10
Step 5: use this rule: axb/c=ab/c 5x3/10
Step 6: simplify 5x3 to 15 so 15/10
Step 7: simplify to 3/2
Last step: Convert to a mixed fraction.. Which would leave us with 1 1/2 or 1.5 in decimal form.
Hope this helps! :)
three consecutive semi
-primes between 30 and 40 are
Answer:
2x = 80. On dividing both sides by 2, we obtain. x = 40. x + 15 = 40 + 15 = 55. Hence ... Let the three consecutive multiples of 8 be 8x, 8(x + 1), 8(x + 2). Sum of ... Number after interchanging = 10 × 3x + x = 30x + x = 31x.

the arrow head pointed towards negative direction... and the unshaded circle shows that the value is less from that point...so the answer is x less than 5
A triangle has sides with lengths of 15 inches, 20 inches, and 25 inches. Is it a right triangle?
37 inches
Hope this helps!
Answer:
Yes.
Step-by-step explanation:
If the side lengths verify in the Pythagorean theorem, then it is a right triangle.
a² + b² = c²
15² + 20² = 25²
225 + 400 = 625
625 = 625
Since these values come out true when using the Pythagorean Theorem, this triangle is a right trinagle.

In July 2008, a forest fire near the Park Yosemite National burned about 53 miles squares of forest. If a square mile equals 640 acres, about how many acres of forest were burned?
Answer:
33,920 acres of forest were burned.
Step-by-step explanation:
In this case, since you know that a square mile is equal to 640 acres, you can use a rule of three to find the acres that are equivalent to 53 square miles:
1 square mile → 640 acres
53 square miles → x
x=(53*640)/1
x=33,920 acres
According to this, the answer is that 33,920 acres of forest were burned.
Find the length of a. Round to 3 decimals.
Answer:
a ≈ 22.184
Step-by-step explanation:
Using the Cosine rule in Δ ABC
a² = b² + c² - 2bc cosA
Here b = 15, c = 12 and A = 110° , then
a² = 15² + 12² - (2 × 15 × 12 × cos110° )
= 225 + 144 - 360 cos110°
= 369 - 360 cos110°
= 492.12725.. ( take the square root of both sides )
a = [tex]\sqrt{x492.12725}[/tex] ≈ 22.184 ( to 3 dec. places )
need the roots, please help

A triangle is formed with side lengths of 7 inches, 24 inches, and 25 inches. Is the triangle a right triangle?
A
The triangle is a right triangle because 2(7)+2(24)=2(25) .
B
The triangle is a right triangle because 7^2+24^2=25^2 .
C
The triangle is not a right triangle because 25^2−24^2=7^2 .
D
The triangle is not a right triangle because 7^2+^25^2=24^2 .
Step-by-step explanation:
The traingle in Question B and A are right traingle because..If you use pythagoras theorem in those two questions,the sum of square of smaller two sides will be equal to the square larger side. Therefore they are rt.triangle. In D the case is opposite. As the sum of square of two smaller sides are comparatively more than larger sidei.e. hypotenuse. So it is not rt. triangle. This is your answer.
The infield of a baseball diamond is shaped like a square. Each side is 90 feet long.
What is the area of the infield?
Answer:
8,100
Step-by-step explanation:
To get the area of a square you must multiply one length by width 90 x 90 = 8100
The area of the infield with each side 90 feet long is,
⇒ Area of the infield = 8100 feet²
What is mean by Multiplication?The multiplication means to add or sum a number to itself a particular number of times. And, The Multiplication can be viewed by a process of repeated addition.
We have to given that;
The infield of a baseball diamond is shaped like a square.
And, Each side is 90 feet long.
Hence, The area of the infield is,
⇒ Area of the infield = side²
Here, We have;
Side of infield = 90 feet
Hence, We get;
⇒ Area = 90²
⇒ Area = 90 x 90 feet²
⇒ Area = 8100 feet²
Therefore, We get the correct answer is;
The area of the infield with each side 90 feet long is,
⇒ Area of the infield = 8100 feet²
