Answer:
An equation is needed to evaluate h(0).
When you evaluate h(0), you find the y-intercept of the graph because the independent variable inside the brackets, probably x or t, equates to 0.
The problem is needed for its context to be explained.
Although in most math problems, when h(x) form is used, h usually represents height.
I assume h(0) is the initial height, maybe the height that the rocket was launched or the height that the person who threw the ball is.

Tell whether the triangle with the given side lengths is a right triangle. Y/N question
Answer:
No.
Step-by-step explanation:
33^2 + 56^2 is not equal to 66^2. I squared these numbers because that is how I can find out and see if the Pythagorean Theorem (a^2 + b^2 = c^2) is true for this.
Answer:
no , it is not a right triangle.
Step-by-step explanation:
according to the pythagoras theorem to be the right angled triangle the sum of square of two smaller sides of triangle must be equal to the square of it's hypotenuse.
Here , 66 is largest side so it is hypotenuse and other two sides are the legs of the triangle.
pythagoras theorem:
a^2 + b^2 = c^2
33^2 + 56^2 = 66^2
1089 + 3136 = 4356
4225 = 4356
since both sides are not equal it can be concluded that the given side lengths does not form right triangle.
The solution is n=-2 verified as a solution to the equation 1.4n + 2 = 2n + 3.2. What is the last line of the justification?
Answer:
- 0.8 = - 0.8
n = - 2 is a solution.
Step-by-step explanation:
1.4n + 2 = 2n + 3.2
1.4(- 2) + 2 = 2(- 2) + 3.2
- 2.8 + 2 = - 4 + 3.2
- 0.8 = - 0.8
How to solve
1.4n + 2 = 2n + 3.2
1.4n + 2 - 2 = 2n + 3.2 - 2
1.4n = 2n + 1.2
1.4n - 2n = 2n - 2n + 1.2
- 0.6n = 1.2
- 0.6n ÷ - 0.6 = 1.2 ÷ - 0.6
n = - 2

Answer:
m = 5, n = 2
Step-by-step explanation:
[tex]5m - 3 n = 19\\m - 6n = - 7 \ => m = -7 + 6n\\\\Substitute \ m \ in \ 5m - 3n = 19\\\\5(-7 + 6n) - 3n = 19\\-35 + 30n -3n = 19\\27n = 19 + 35 \\27n = 54 \\n = 2\\\\Substitute \ n = 2 \ in \ m = -7 + 6n\\\\m = -7 + (6 \times 2) = -7 + 12 = 5[/tex]
The perimeter of a rectangle is 84 cm. If the length is 29 cm write an equation you can use to answer this question
Answer:
The perimeter of a rectangle has the general formula P=2L+2W. Since you know P and L, you can plug those values into the formula and solve for W.
Hope this answer is right!!
Answer:
Width: 13
Area: 42
Step-by-step explanation:
A rectangle has equal opposite sides, so if you know one side, you know that the opposite side will be the same. Then you can subtract it from the perimeter, and divide the remaining number in half because it represents the other opposite sides. If you were trying to find the area, do that to find the length and width. 29x13=42, so the area is 42. If you were trying to find the width, that would be 13 because
29+29=58
84-58=26
And 26/2=13

The national park has a new kiosk which visitors pass through as they enter the park. The kiosk is in the shape of a cylinder with a diameter of 5 meters and a height of 3 meters and a conical roof that measures 2 meters in height. What is the volume of the kiosk? Round your answer to the nearest cubic meter
Answer:
The volume of the kiosk is 72 m³.
Step-by-step explanation:
The volume of the kiosk is given by the sum of the volume of a cylinder ([tex]V_{cy}[/tex]) and the volume of a cone ([tex]V_{c}[/tex]):
[tex] V = V_{cy} + V_{c} = \pi r^{2}h_{cy} + \frac{1}{3}\pi r^{2}h_{c} [/tex]
Where:
r: is the radius of the cylinder and the cone = d/2 = 5/2 = 2.5 m
d: is the diameter = 5 m
[tex]h_{cy}[/tex]: is the height of the cylinder = 3 m
[tex]h_{c}[/tex]: is the height of the cone = 2 m
Hence, the volume is:
[tex] V = \pi (2.5 m)^{2}(3 m + \frac{1}{3}*2 m) = 72 m^{3} [/tex]
Therefore, the volume of the kiosk is 72 m³.

40
41
42
43
Answer:
4²
Step-by-step explanation:
simplified expression of 4 power 4 multiplied by 4 power 3 over 4 power 5.
Answer:
4^2
Step-by-step explanation:
(4^4*4^3)/4^5
4^4 * 4^3 = 4^7 because of an exponent multiplication property, when exponents of the same number multiply, they can just add
4^7/4^5
4^7-5
= 4^2 Because..
another exponent property is that if the exponents of the same number divide, they can subtract! The opposite of the other property!
5) If (x - 5) is a factor of 2r3 - 7px + (p - 12),
find the value of p.
{ANS: p = 7)
Answer:
the value of p is 7
Step-by-step explanation:
Given function;
f(x) = 2x³ - 7px + (p - 12)
factor of the given function = x - 5
Apply remainder theorem to solve for p
f(x - 5) = 0
x - 5 = 0
x = 5
f(5) = 2(5)³ - 7p(5) + (p - 12) = 0
2(125) - 35p + p - 12 = 0
250 - 34p - 12 = 0
238 - 34p = 0
34p = 238
p = 238/34
p = 7
Therefore, the value of p is 7

Angle C = 95 degreesAngle D = 72 degreesAngle F = 108 degreesArc CFE = 216 degrees================================================
Explanations:
For any inscribed quadrilateral like this, the opposite angles are always supplementary. So that means C+E = 180. Plugging in E = 85 leads to C = 95.Angle D is an inscribed angle that subtends arc CFE. By the inscribed angle theorem, the inscribed angle is half that of the arc it cuts off, so angle D is half of 144 degrees at 144/2 = 72 degrees.Use the idea mentioned in problem 1. So we'll have F+D = 180. Plug in D = 72 to find that F = 108.Arcs CDE and CFE form a full circle. So the arc measures must add to 360 degrees. We simply subtract 144 from 360 to get the answer 216. As an alternative, you can use the idea mentioned in problem 2, but work in reverse.please help me help help help

in a survey of 100 cars,47 were white,23 were blue and 30 were red.express each of these numbers as a percentage of the total.
Answer:
white- 47% Blue-23% Red- 30%
Step-by-step explanation:
White cars- (47/100)*100= 47%
Blue cars- (23/100)*100=23%
Red cars- (30/100)*100=30%
Answer:
White 47 percent, 23 percent blue 30 percent red.
47+23+30=100 percent
Step-by-step explanation:
So to get the percentages you first have to get the numbers that you need in this case it is 47,30,and 23.
After that we have to first multiply the numbers(47,30,23)by 100 because
100 hundred is our total percent so 47x100=4700 30x100=3000
and 23x100=2300.And 47x100=4700 30x100=3000
and lastly 23x100=2300.So after we multiply the numbers by 100 hundred we have to divide so we see there's 100 cars so we divide by that because that is the total amount of cars and if we divide all our numbers by 100 we will get the answer,
4700/100=47 percent 3000/100=30 percent 2300/100=23 percent
and to check our answer is right we have to add all our number percentages up to see if all the numbers add up to 100.(percentage)so 47+30+23=100
So that means our answer is right.

SHORT ANSWER IS B.
Angles in a triangle add up to equal 180 degrees
Hence, 40x - 27 + 25 - 2x + 26 + x = 180
( Note that we just created an equation that we can use to solve for x)
We now solve for x using the equation we created
40x - 27 + 25 - 2x + 26 + x = 180
Combine like terms
39x + 24 = 180
Subtract 24 from both sides
39x = 156
Divide both sides by 39

Answer:
B. 2w^2 + 2w + 36
Step-by-step explanation:
The equation to find the perimeter of anything is: Length + Length + Width + Width = Perimeter.
Applying this logic to this problem, the equation would be as follows:
[tex]w^{2} + 13 + w^{2} + 13 + w+5+w+5[/tex]
Then, we simplify. The like terms go together, and you have your solution.
[tex]2w^{2} + 2w+36[/tex]
So there’s two cell phones the length on first is 8.4 inches the width on the first cell phone is 5.6 inches. On the second cell phone the length is 9.21 inches. The length and width of the two cell phones are proportional. What is the width, inches of the larger of the cell phone?
Answer:
The width, in inches of the larger cell phone is 6.14 inches.
Step-by-step explanation:
To solve we must set up a ratio.
[tex]\frac{8.4}{5.6} = \frac{9.21}{y}[/tex]
After setting this ratio up, we can cross multiply to solve for y.
8.4(y) = 5.6(9.21)
8.4(y) = 51. 576
To get y alone we divide by 8.4 on both sides.
y = 6.14
The width, in inches of the larger cell phone is 6.14 inches.
