Answer:
The maximum height of the rocket is 64 ft.
Step-by-step explanation:
The -t^2 term tells us that the graph of this function is a parabola that opens down. The x-coordinate of the axis of symmetry is
-b
x = -----------
2a
which here is:
-32
x = ------------ = 1
2(-16)
The value of this function at t = 1 is
h(1) = -16(1)^2 + 32(1) + 48, or 64 ft
The maximum height of the rocket is 64 ft.

Answer:
1. $21
2. $56
Step-by-step explanation:
1.
100% - 30% = 70%
70% * $30 = 0.7 * $30 = $21
2.
100% - 20% = 80%
80% * $70 = 0.8 * $70 = $56
Step-by-step explanation:
The equation for percentages is (percent over 100) times (x over total)
So for the table the equation is 30/100 * x/30
You cross multiply your total x percent and divide by 100.
So 30 * 30 = 900
900 / 100 = 9
30% of 30 is 9.
Now subtract your answer from the original total (30 - 9 = 21)
So the sale price of the tennis table is $21.
Now repeat for your other equation
Your equation is 20/100 * x/70
So 20 * 70 = 1400
1400 / 100 = 14
20% of 70 is 14.
Now subtract your answer from the original total (70 - 14 = 56)
So the sale price of the easel is $56.

In the equation y = X - 5, the y-intercept is
Answer:
(0, -5)
Step-by-step explanation:
The y-intercept of a graph is where the graph of the function intersects the y-axis. This means that the x-coordinate of the point is zero. To find the y-intercept of a line, when given the equation of the line, substitute (0) in for (x) and solve the equation,
y = x - 5
x = 0
y = 0 - 5
y = -5
This gives the resulting point of (0, -5) for the y-intercept of the line.

Answer:
1260
Step-by-step explanation:
12/72 is 1/6 of the students going to the play
210 students go to play
210 times 6 is 1260
Answer:
1260 students
Step-by-step explanation:
Let x be the number of students in the school.
12 of the 72 students surveyed said they would attend the school pay so
(12/72)x=(1/6)x gives the predicted number of ticket sales. (Here 12*6=72 so it becomes 1/6)
The table shows 210 students purchased tickets so( 1/6)x=210
x=6*210
x=1260 students attend the school.

95
Z
215°
W
30°
Answer:
so the answer is 95°
Step-by-step explanation:
The two angles on a line add up to 180° or are supplementary, so we can find the inside angle x by doing 180-150=30°. Now that we know inside x is 30, if we add 30+65, we get 95, and 180-95=85°. Then to find angle xzw, just do 180-85 to get 95°.

solve the equation by completing the square. round to the nearest tenth if necessary.
x^2 - 12x + 9 = 0
Answer:
Step-by-step explanation:
Solution by completing the square for:
x2−12x+9=0
Keep x terms on the left and move
the constant to the right side
by subtracting it on both sides
x2−12x=−9
Take half of the x term and square it
[−12⋅1/2]^2=36
then add the result to both sides
x^2−12x+36=−9+36
Rewrite the perfect square on the left
(x−6)^2=−9+36
and combine terms on the right
(x−6)^2=27
Take the square root of both sides
x−6=±27−−√
Simplify the Radical term (1):
x−6=±3–√3
Isolate the x on the left side and
solve for x (1)
x=6±3–√3
therefore (2)
x=6+3–√3
x=6−3–√3
which becomes
x=11.1962
x=0.803848

Describe and correct the error in finding the area of a sector with a radius of 6 centimeters and a central angle of 40
Answer:
12.56
Step-by-step explanation:
Remark
Since we don't have anything other than the question, all I can do is answer the question. You are left with the task of figuring out the error.
Formula
Area = (central angle divided by 360 ) * pi r^2
Solution
Area = (40 /360) * 3.14 * 6^2
Area = 1/9 * 3.14 * 36
Area = 4 * 3.14
Area = 12.56

Can a regular polygon have an interior angles of 169?
Answer:
No.
Step-by-step explanation:
If it is a regular polygon then the sum of its exterior angles add up to 360 degrees. The number of sides in such a polygon = 360 / exterior angle.
Here each exterior angle = 180-169 = 11 degrees,
Now 11 is not a factor of 360 and if we try to find the number of sides we don't get a whole number, so the answer is NO.
An interior angle 169° cannot form an regular polygon.
What is a polygon?The polygons are the closed shape that has sides and vertices. A regular polygon has all its interior angles equal to each other. An interior angle of a polygon is an angle formed inside the two adjacent sides of a polygon.
For the given situation,
An interior angle of the polygon = 169
The angle of the sum of all the types of interior angles is always equal to 180 degrees.
⇒ [tex]180-169=11[/tex]
Number of sides can be found by dividing the angle by 360°.
We cannot divide 360 by 11, because 11 is not the factor of 360.
Hence we can conclude that an interior angle 169° cannot form an regular polygon.

Step-by-step explanation:
Line passes through the point [tex] (12,\: 5) =(x_1,\: y_1) [/tex] and has a slope (m) = 2
Equation of line in point slope form is given as:
