Answer:
height:6
if the base is a square that means all the side lengths are equivalent so it would be 8 for side lengths, and the volume is 128. plug it in with the formula to get 6
The height of a pyramid is 8cm
How to find the volume of a square based right pyramid?Supposing that:
The length of the sides of the square base the pyramid has = b units
The height of the considered square based pyramid = h units,
Then, its volume is given by: [tex]V = \dfrac{1}{3} \times b^2 \times h \: \rm unit^3[/tex]
Given;
The volume of pyramid= 128cm3
Length of side of square base= 8cm
Now,
128=1/3 x 8x8xh
128= 64/3 xh
h= 128x3/64
h=8
Therefore, the height with the volume 128cm3 will be 8cm

It is given that yvaries directly as x. If y= 5 when x= 4 determine the constant of variation,
Answer:
[tex]k=\dfrac{5}{4}[/tex]
Step-by-step explanation:
Given that,
y varies directly as x. It means,
y = kx
Where
k is the constant of variation
or
[tex]k=\dfrac{y}{x}\\\\k=\dfrac{5}{4}[/tex]
So, the constant of variation is [tex]\dfrac{5}{4}[/tex].
A health club manager wants to determine whether the members would prefer a new sauna or a new steam room. The club surveys 50 of its 600 members. What is the population of this study? The population is all 50 members of the health club. The population is all 600 and 50 members of the health club. The population is all 600 members of the health club. The population is all 30,000 members of the health club.
Answer:
The population is all 600 members of the health club
Explanation:
50 members were chosen out of all 600 members thereby telling us that the sample of the study/survey is 50 members while the population is all 600 members. A sample represents the population and is collected from the population to make it less tedious to study and make conclusions on the population. For example, given that the population of a study are individuals or objects of common characteristics, 50 members tell the needed story and relays the characteristics and/or definition of the whole population, thereby forming a basis to make a conclusion on the population.

Answer:
Step-by-step explanation:
4) Angles opposite to equal sides are equal
45 + 45 + x = 180 {Angle sum property}
90 +x = 180 {Subtract 90 from both sides}
x = 180 - 90
x = 90
120 +y + y = 180 {Angle sum property}
120 +2y = 180 {Subtract 120 from both sides
2y =180 - 120
2y = 60 {Divide both sides by 2}
y = 60/2
y = 30
5)All sides are equal. so this is a equilateral triangle.
So each angle of equilateral triangle = 60
4x = 60
x = 60/4
x = 15
y = 60 +60 {Exterior of triangle equal sum of opposite interior angles}
y = 120
6) All sides are equal. so this is a equilateral triangle.
So each angle of equilateral triangle = 60
y - 10 = 60 {add 10 to both side}
y = 60 + 10
y = 70
x + 5 = 60 {Subtract 5 from both sides}
x = 60 - 5
x = 55

Given u = 4v – 3t, find
(a)the value of u when v = 5 and t = -1,
(b) the value of t when v = 2 and u = -10.
Answer:
u = 23 and t = 6
Step-by-step explanation:
Given
u = 4v - 3t
(a)
u = 4(5) - 3(- 1) = 20 + 3 = 23
(b)
- 10 = 4(2) - 3t
- 10 = 8 - 3t ( subtract 8 from both sides )
- 18 = - 3t ( divide both sides by - 3 )
6 = t
Evaluate the exponential expression. 14^2
Answer:196
Step-by-step explanation:
Answer:
196
Step-by-step explanation:
Exponential expressions are just a way to write powers in short form. The exponent indicates the number of times the base is used as a factor. So in the case of 32, it can be written as 2 × 2 × 2 × 2 × 2=25, where 2 is the “base” and 5 is the “exponent”. We read this expression as “two to the fifth power”.

There is a cylinder with a height of 8 units and a volume of 72 cubic units. What is the radius of the cylinder?
Answer:
Radius of the cylinder = 1.69 units
Step-by-step explanation:
Volume of a cylinder is given by the expression,
Volume = Area of the circular base × Height of the cylinder
Area of the circular base = πr²
Here, r = Radius of the circular base
Volume of the cylinder = πr²h
By substituting the values given in the question,
72 = π(r)²8
r² = [tex]\frac{9}{\pi }[/tex]
r² = 2.865
r = 1.692
r = 1.69 units

a2 = -8 and a5 = -512
Find a10
Answer:
The value of a₁₀ is -1352
Step-by-step explanation:
a₂ = -8
a₅ = -512
Now,
a₂ = -8 can be written as
a + d = -8 ...(1) and
a₅ = -512 can be written as
a + 4d = -512 ...(2)
Now, from equation (2) we get,
a + 4d = - 512
a + d + 3d = - 512
(-8) + 3d = - 512 (.°. a + d = -8)
3d = - 512 + 8
3d = - 504
d = - 504 ÷ 3
d = - 168
Now, for the value of a put the value of d = -168 in equation (1)
a + d = -8
a + (-168) = -8
a - 168 = -8
a = 168 - 8
a = 160
Now, For a₁₀
a₁₀ = a + 9d
a₁₀ = 160 + 9(-168)
a₁₀ = 160 - 1512
a₁₀ = -1352
Thus, The value of a₁₀ is -1352

Answer:
[tex]x = 9[/tex]
[tex]y = 17[/tex]
Step-by-step explanation:
This is a cyclic quadralterial so opposite angles are supplementary.
The x variables add up to 180 so
[tex]11x + 8 + 8x + 1 = 180[/tex]
[tex]19x + 9 = 180[/tex]
[tex]19x = 171[/tex]
[tex]x = 9[/tex]
The y variables add up to 180.
[tex]6y - 4 + 5y - 3 = 180[/tex]
[tex]11y - 7 = 180[/tex]
[tex]11y = 187[/tex]
[tex]y = 17[/tex]

Given:
[tex](\sin x)^2+(\cos x)^2=1[/tex]
[tex]\cos \theta = \dfrac{4\sqrt{2}}{7}[/tex]
To find:
The value of [tex]\sin \theta[/tex].
Solution:
We have,
[tex]\cos \theta = \dfrac{4\sqrt{2}}{7}[/tex]
Putting this value in the Pythagorean identity, we get
[tex](\sin \theta)^2+(\cos \theta)^2=1[/tex]
[tex](\sin \theta)^2+\left(\dfrac{4\sqrt{2}}{7}\right)^2=1[/tex]
[tex](\sin \theta)^2+\dfrac{16(2)}{49}=1[/tex]
[tex](\sin \theta)^2+\dfrac{32}{49}=1[/tex]
[tex](\sin \theta)^2=1-\dfrac{32}{49}[/tex]
[tex](\sin \theta)^2=\dfrac{49-32}{49}[/tex]
[tex](\sin \theta)^2=\dfrac{17}{49}[/tex]
Taking square root on both sides, we get
[tex]\sin \theta=\pm \sqrt{\dfrac{17}{49}}[/tex]
[tex]\sin \theta=\pm \dfrac{\sqrt{17}}{7}[/tex]
The given value of [tex]\sin \theta[/tex] is positive. So, [tex]\sin \theta= \dfrac{\sqrt{17}}{7}[/tex].
Therefore, the value of value [tex]\sin \theta[/tex] is [tex]\sin \theta= \dfrac{\sqrt{17}}{7}[/tex].

What is the unknown side length, p, in the triangle shown below?
Answer:
9
Step-by-step explanation:
To solve this, you need to find the proportion.
p is a leg of the large triangle, and the leg to the small triangle is 6.
8 is another leg of the small triangle, and 8+4 is the leg of the large triangle.
So [tex]\frac{small triangle}{big triangle} = \frac{small triangle}{big triangle\\}[/tex]
[tex]\frac{8}{12} =\frac{6}{p}[/tex]
[tex]\frac{2}{3} =\frac{6}{p}[/tex]
cross multiply to get 2p=18
divide both sides by 2
p=9.
