A projectile is launched from a tower 64 feet above the ground into the air with an initial velocity of 48 feet per second. How many seconds is the projectile in the air before it hits the ground?
Answer:
I hope this helps you
Step-by-step explanation:
To define the time of flight equation, we should split the formulas into two cases:
Launching projectile from the ground (initial height = 0)
t = 2 * V₀ * sin(α) / g.
Launching projectile from some height (so initial height > 0)
t = [V₀ * sin(α) + √((V₀ * sin(α))² + 2 * g * h)] / g.

What is the approximate volume of the cone?
Use 3.14 for π.
A 1206 cm³
B 2170 cm³
C 3260 cm³
C 6510 cm³
Answer:
A. 1206 cm³
Step-by-step explanation:
We have a cone and are asked to find the approximate volume of it.
Keep in mind we are using π for 3.14
The forumla of a cone is V = πr²[tex]\frac{h}{3}[/tex]
We know the radius = 12
and the height = 8
Substitute :
V = π12²[tex]\frac{8}{3}[/tex]
Since these are multiplied with each other, we can first start off with multiplying the fraction, including with factoring 12²:
V = [tex]\frac{2^4*3^2*8\pi }{3}[/tex]
Cancel the common factor - 3 :
V = [tex]2^4 * 8 * 3\pi[/tex]
Multiply 8 and 3π :
V = [tex]2^4 * 24\pi[/tex]
Solve the exponent :
V = [tex]16 * 24\pi[/tex]
Multiply :
V = [tex]384\pi[/tex]
Multiply for the final answer :
1205.76 cm³
which can be rounded up to
A. 1206 cm³
If the bill for dinner at a restaurant is $65.00, what is the total bill with a 15% tip?
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $65.00 meal cost is.This is always done by multiplying 0.15 by $65.00, or 0.15 x $65.00=$9.75.
So, the amount of tip you are going to leave is $9.75.
This makes the total cost of your meal: $65.00 + $9.75 = $74.75.
ANSWER: $74.75
Someone help The question is to find the volume of the cylinder in terms of pi. The formula for Volume is V=pi*R^2*H right? Radius is 3.4m and the height is 11m So i got 399... Around but none of those are the answer choices i know when questions ask in terms of pi, i always get confused can anyone help me please?! A.) 127.16 B.) 74.8 C.) 432.34 D.) 63.58 P.S - pi is after each answer
Answer:
A.) 127.16π
Step-by-step explanation:
Volume of a cylinder = πr²h
Radius, r = 3.4m
Height, h = 11m
Pi = π
Find the volume in terms of pi
Volume of a cylinder = πr²h
= π * (3.4)² * 11
= π * 11.56 * 11
= 127.16π³
The correct answer is
A.) 127.16π

Can someone please find the area please
Answer:
35 square units
Step-by-step explanation:
Area is length • width, so you just have to count the number of units long and wide the rectangle is.
The length is 5 units and the width is 7 units, therefore, you would do 5•7.
5•7=35

Select the triangle that is similar to ABC
Answer:
C is the correct answer.
Step-by-step explanation:
All of the angles in a triangle add up to 180 degrees. 65+80=145 and when you do 180-145, you get 35 degrees. You can check to see if it's correct by adding 35, 65, and 80 together.
[tex]65+80=145[/tex]
[tex]180-145=35[/tex]
[tex]35+65+80=180[/tex]
The opposite angle of the triangle is similar.ΔDEF is similar to ΔABC. Option C is correct.
What exactly is a triangle?
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
ΔDEF
∠F=80°
∠F=35°
The sum of the angle of the triangle DEF is;
∠D+∠E+∠F=180°
∠D=180°-115°
∠D=65°
In ABC
/_A = 65°
/_B= 80°
∠A+∠B+∠C=180°
∠D=180°-145
∠D=35°
The opposite angle of the triangle is similar.ΔDEF is similar to ΔABC.
Hence,option C is correct.

2/x =3/4 what is x? im doing a math test help
Answer:
[tex]x=\frac{3}{4}[/tex]
Step-by-step explanation:
First, we know we want to get x all by itself. So, let's multiply it by 2.
[tex]\frac{2}{x}(2) = \frac{3}{4}(2)\\[/tex]
Then we have:
[tex]x=\frac{3}{4}(2)[/tex]
Now, we have to simplify the right side of the equation, so, let's rewrite it.
[tex]x=\frac{3*2}{4*2}[/tex]
All we have to do now is simplify.
[tex]x=\frac{6}{8}[/tex]
Luckily (and ironically) both the numerator and denominator are divisible by 2, so...
[tex]x=\frac{3}{4}[/tex]

write the slope-intercept form of the equation of each line.
Answer:
y = 3x + 2
Step-by-step explanation:
Let's identify two clear points on this line. I can see (0, 2) and (-1, -1)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-1 - 2) / (-1 - 0)
Simplify the parentheses.
= (-3) / (-1)
Simplify the fraction.
-3/-1
= 3
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 3x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the first point (0, 2). Plug in the x and y values into the x and y of the standard equation.
2 = 3(0) + b
To find b, multiply the slope and the input of x(0)
2 = 0 + b
Now, we are left with 0 + b.
2 = b
Plug this into your standard equation.
y = 3x + 2
This is your equation.
Hope this helps!
