2. A(an) ______________of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)
Answer:
A(an) altitude of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)
Step-by-step explanation:
AN ALTITUDE - An altitude of a triangle is a line segment that passes through a vertex and is perpendicular to (i.e. forms a right angle with) the base line (the side opposite the vertex). The expanded base of the altitude is the line that contains the opposing side. The foot of the altitude is the point where the extended base meets the altitude. The area of a triangle can be calculated using altitudes: one half of the product of an altitude's length and its base's length equals the triangle's area. As a result, the longest altitude is perpendicular to the triangle's shortest side. Through trigonometric functions, the heights are also connected to the triangle's sides.
Hence , the answer is an altitude .
f(x) = 4x2 + 5x - 3
g(x) = 4x2 – 3x2 + 5
Find (f +g)(x).
Answer:
5x + 12
Step-by-step explanation:
simplify f(x) and g(x)
g(x) = 4*2 -3*2 +5
g(x) = 8 -6 + 5
g(x) = 7
and
f(x) = 4*2 + 5x -3
f(x) = 8 + 5x - 3
f(x) = 5x + 5
So (f + g)(x) = f(x) + g(x)
(f + g)(x) = (5x + 5) + (7)
(f + g)(x) = 5x + 12

Answer:
allen= y=3/2+2 billy= y= 3/2+4
Step-by-step explanation:
ok both of the equation are (almost) the same except for the y intercepts.
y=mx+b... you are learning about that hopefully!
so. each of their trees are growing by 3... feet I'll just say feet. that means the slope is three because they are each going up that much. you also have to pay attention to the fact that the year is going up by two, so your tree is actually growing by 1.5 (3 halves) feet each year. now you have to find the y intercept by back tracking. remember that the y intercept is where y is zero and x is whatever it is.
if you go back three on allen, the y intercept is 2 and if you go back on billy, the y intercept is 4.
as for the second question, the lines are parallel. they have the exact same slope so that means that they will never cross because billy's line is higher then allens, billy's tree will always be higher

Step-by-step explanation:
what is the value of x? i need the work for it as well thank you so much!
Answer:
x=19
Step-by-step explanation:
okay so all those angles there are pretty simple. because of the vertical angles theorem, the angles that go across from each other are equal to each other. On a thing like this those intersections are congruent. So knowing this we can assume that (6x+4)=118. so if you solve the basic algebra for that (you can use mathpapa or smt if you really need the work for that) then it comes out as x=19 which you can check.
6x+4=118
subtract 4 from both sides
6x=114
divide by 6 on both sides
x=19
Hope this helps!

PLEASE HELP ME WITH THIS ALGEBRA PROBLEM!!
Answer:
Solution given.
centre (h,k):(-6,1)
radius (r)=2
we have
equation of a circle is:
(x-h)²+(y-k)²=r²
(x+6)²+(y-1)²=2²
(x+6)²+(y-1)²=4 is a required equation of a circle.
Find the height of a cylinder when the surface area is 1004.80 cm squared and the radius is 10 cm.
Step-by-step explanation:
[tex]volume =\pi {r}^{2}h[/tex]
[tex]area = \pi {r}^{2} [/tex]
CALCULATIONremember
[tex]\pi = 22 \div 7[/tex]
So, we will just place the area and equate it to the unknown volume including the height
1004.80 = 22/7 × 10× 10 × h
1004.80 = 314.26h
h = 3.197

What is the formula for prism
Answer:
The formula for the volume of a triangular prism is:
V=(l)(w)(h)
Where l is the length of the triangle, w is the width of the triangle, and h is the height of the prism
The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm.

At a certain instant the edge of a cube is 7 inches long and the volume is increasing at the rate of 3 cubic inches per minute. How fast is the surface area of the cube increasing
Answer:
The surface area increases at 12/7 square inches per minute
Step-by-step explanation:
Given
[tex]l = 7[/tex] --- side length
[tex]\frac{dV}{dt} = 3in^3/min[/tex] --- Rate at which volume increases
Required
The rate at [tex]which[/tex] the [tex]surface[/tex] area [tex]increases[/tex]
The volume of a cube is:
[tex]V = l^3[/tex]
Differentiate with respect to time
[tex]\frac{dV}{dt} = 3l^2 \cdot \frac{dl}{dt}[/tex]
When [tex]l = 7[/tex] and [tex]\frac{dV}{dt} = 3in^3/min[/tex]
The expression becomes:
[tex]3 = 3 * 7^2 \cdot \frac{dl}{dt}[/tex]
Divide both sides by 3
[tex]1 = 7^2 \cdot \frac{dl}{dt}[/tex]
[tex]1 = 49 \cdot \frac{dl}{dt}[/tex]
Divide both sides by 49
[tex]\frac{dl}{dt} = \frac{1}{49}[/tex]
The surface area is calculated as:
[tex]A= 6l^2[/tex]
Differentiate with respect to time
[tex]\frac{dA}{dt} = 12l\frac{dl}{dt}[/tex]
Substitute: [tex]\frac{dl}{dt} = \frac{1}{49}[/tex] and [tex]l = 7[/tex]
[tex]\frac{dA}{dt} = 12 * 7 *\frac{1}{49}[/tex]
[tex]\frac{dA}{dt} = 12 *\frac{1}{7}[/tex]
[tex]\frac{dA}{dt} = \frac{12}{7}[/tex]
The surface area increases at 12/7 square inches per minute

Answer:
C 19.2
Step-by-step explanation:
Corresponding parts have the same proportion
x/24 = 20.8/26
multiply both sides by 24
x = 20.8/26 * 24
x = 19.2
Answer:
C
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AC}{DF}[/tex] = [tex]\frac{AB}{DE}[/tex] , substitute values
[tex]\frac{x}{24}[/tex] = [tex]\frac{20.8}{26}[/tex] ( cross- multiply )
26x = 499.2 ( divide both sides by 26 )
x = 19.2 → C

Jake throws a stone off a bridge into the river. The stones height in meters above the water is based on the time in seconds after jake threw the stone. The quadratic equation y=-5^2+10x+15 represents the scenario
Answer:
The stone will hit the water after 3 seconds
Step-by-step explanation:
Given
[tex]y = -5x^2 + 10x +15[/tex]
Required
At what time will the stone enter the water
When the stone enters the water;
[tex]y = 0[/tex]
So, we have:
[tex]-5x^2 + 10x +15 = 0[/tex]
Divide through by -5
[tex]x^2 -2x -3 = 0[/tex]
Expand
[tex]x^2 +x -3x -3 = 0[/tex]
Factorize
[tex]x(x +1) -3(x +1) = 0[/tex]
Factor out x + 1
[tex](x -3) (x +1) = 0[/tex]
Solve for x
[tex]x - 3 = 0\ or\ x + 1 = 0[/tex]
[tex]x = 3\ or\ x = -1[/tex]
x (time) cannot be negative.
So:
[tex]x = 3[/tex]
