The trajectory of a golf ball hit from a tee on the ground at an angle of 40 degrees with an initial
speed of 50 meters per second can be modeled by the parabola f(x) = 0.84x - 0.0033x2, where the
x-axis is the ground. Find the height of the highest point of the trajectory and the horizontal distance
the golf ball travels before hitting the ground.
PLEASE HELP ME IM USING ALL MY
POINTS
Answer:
53.45 m254.55 mStep-by-step explanation:
Given function:
f(x) = 0.84x - 0.0033x²Rewrite in the standard form:
f(x) = - 0.0033x² + 0.84xThe maximum height is the vertex with x- coordinate -b/2a, which is:
x = -0.84/2(-0.0033) ≈ 127.27The highest point is:
f(127.27) = -0.0033(127.27)² + 0.84(127.27) ≈ 53.45 mThe horizontal distance the golf ball travels before hitting the ground:
f(x) = 0- 0.0033x² + 0.84x = 033x² - 8400x = 0x(33x - 8400) = 0x = 0- initial point33x = 8400 ⇒ x = 8400/33 ≈ 254.55 mPlease help need this ASAP!!!

Answer:
1728 in²
Step-by-step explanation:
For the area of B, you need to find the length and width (height and base, whatever you want to call it).
For the height, you would need to do: 144 - 36 - 24 - 36 = 48 inches
For the base, you would need to do: 60 - 24 = 36 inches
Now you multiply the base and height to get the area: 48 x 36 = 1728 in²

The diameter of a circle is 34 feet. What is the circle’s area?
Use 3.14 as pi
The radius of the circle is 17 feet. Then the area of the circle is 907.46 square feet.
What is the area of the circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. Then the area of the circle will be given as,
A = πr² square units
The diameter of the circle is 34 feet. Then the radius of the circle is calculated as,
r = 34 / 2
d = 17 feet
The area of the circle is calculated as,
A = πr²
A = 3.14 x 17 x 17
A = 907.46 square feet

if side a is 6 feet and side b is 4 feet how long is side c
Answer:
Step-by-step explanation:
If and only if this is a right triangle, the length of side c can be found using the Pythagorean Theorem:
c^2 = (6 ft)^2 + (4 ft)^2 = 36 + 16 = 52 ft
Then the length of side c is √52 ft, or √4√13 ft, or 2√13 ft.
If this is NOT a right triangle, then we must use the Law of Cosines:
c^2 = a^2 + b^2 - 2ab·cos C, where C is the angle opposite side c. Obviously this requires knowing the measure of Angle C.

What is the best estimate of the perimeter of the figure below if each square has a side length of 1 foot? On a coordinate plane, a figure is 30 units around. 26 feet 28 feet 30 feet 39 feet
Answer:
28 feet
Step-by-step explanation:
Since each side length of the square is 1 foot.
Let x represent the length of the small slant side and y represent the length of the long slant side. Hence:
x² = 5² + 1²
x² = 26
x = √26 = 5.1 feet
y² = 6² + 3²
y² = 45
y = 6.7 feet
The perimeter of the figure is the sum of all the sides of the figure, hence:
Perimeter = 11 feet + 4 feet + 5.1 feet + 6.7 feet + 2 feet = 28.8 feet
Therefore the best estimate of the perimeter of the figure below is 28 feet.

Several items in a store are on sale. Complete the table with the correct prices.
Original Price
Percent of Discount
Sale Price
$60 20% __?
$140 65% __?
__? 40% $54.60
__? 10% $10.80
Answer:
1. $48
2.$49
3.$91
4.$12
Step-by-step explanation:
For 1 and 2
To find the sale price, you find out how much is the percentage of the original price. Example :
(20/100)/60 = $12
So $12 is the discount
thus sales price will be $60-$12=$48
Same thing for no.2, find the amount of the percentage and subtract it from the original price
For 3 and 4
To find the original price
1. Subtract the percentage from 100%
2. Multiply the sales price by 100
3. Divide the ans from no.2 by ans from no.1
Example :
100%-40%=60%
$54.60×100=5460
$5460÷60%= $91 (original price)
Same thing for no.4
Hope this helps haha
find the values of x and y
Answer:
see below
Step-by-step explanation:
• find x
use tan rule
tan( 60 degrees) = x / 7
tan ( 60 ) x 7 = 12 . 1
x = 12. 1
• find y
you can either use Pythagoras theorem or the sin rule
let's use sin
sin ( 30 ) = 7 / y
y = 14.0

Answer:
Area of the sector = [tex]\frac{\pi }{8}[/tex] cm²
Step-by-step explanation:
Measure of the given arc = 45°
Central angle formed by the arc = 45°
Formula to be used,
Area of the sector bounded by the arc = [tex]\frac{\text{Central angle}}{360}\times \pi r^{2}[/tex]
Here, r = radius of the circle
Area of the sector = [tex]\frac{45}{360}(\pi)(1)^2[/tex]
= [tex]\frac{\pi }{8}[/tex] cm²
