Step-by-step explanation:
A cone has a base of [tex]5.4[/tex] and a height of [tex]8[/tex]. The diameter is [tex]6[/tex]. What is the volume? If you were to dilate the cone with a scale factor of [tex]2[/tex], what would the new radius be?
Answer:
(I) V = 24π ≈ 75.3982 units³
(II) V = 192π ≈ 603.186 units³

DilationsDiameter: d = 2rVolume of a Cone: [tex]V= \frac{1}{3} \pi r^2h[/tex]Step-by-step explanation:
Step 1: Define
Height h = 8
Diameter d = 6
Base b = 5.4 (not needed in calculations)
Step 2: Find radius r
Substitute: 6 = 2rIsolate r: 3 = rRewrite: r = 3Step 3: Find V of Normal Dimensions
Substitute: [tex]V= \frac{1}{3} \pi (3)^2(8)[/tex]Exponents: [tex]V= \frac{1}{3} \pi (9)(8)[/tex]Multiply: [tex]V= 24 \pi[/tex]Evaluate: [tex]V \approx 75.3982[/tex]Step 4: Find Dilations
Scale Factor: 2
Define radius: r = 3Dilate: r' = 3(2)Multiply: r' = 6Define height: h = 8Dilate: h' = 8(2)Multiply: h' = 16Step 5: Find V of Dilated Dimensions
Substitute: [tex]V= \frac{1}{3} \pi (6)^2(16)[/tex]Exponents: [tex]V= \frac{1}{3} \pi (36)(16)[/tex]Multiply: [tex]V= 192 \pi[/tex]Evaluate: [tex]V \approx 603.186[/tex]find the values of x and y?
Answer:x=20 y=70
Step-by-step explanation:
Answer:
x=20, y=70
Step-by-step explanation:
∠40°+∠adjacent to it =180°
∠adjacent= 180-40=140°
we see that 2 of the sides of one of the small triangles are congruent so that triangle is isoscel so the base angles are congruent as well
because sum of angles in a triangle has to be 180,
140 +x+x=180 so x=20°
from the right triange we see thhat y +90+20 =180 because sum of angle in a triangle has to be 180 so y=70

What is the cost of the bill if a drink costs $3, a meal costs $20, an appetizer costs $5.50 and a slice of cake cost $3. 75?
Place the steps in the correct order for solving the equation
8+- 6 - 5 = 8x + 1 - 3x
= -3 + 2 = 5x +1
= -3 -1 = 4x +1 -1
= -3 + x - x = 5x - +1
= -3 = 4x + 1
1 = 4
= -4 = 42
= x= -1
Answer:
say whaaaaaaaaat
Step-by-step explanation:
Step-by-step explanation:
8+x-6-5=8x+1-3x
-3+x=5x+1
-3+x-x=5x-x+1
-3=4×+1
-3-1=4x+1-1
-4=4x
-4/4=4x/4
x= -1

Answer:
A. because both variables (y and x) cancel each other out because they are equal. The answer to A is 0=6, which is clearly not true. All other choices have a solution that is possible, because at least 1 of the variables doesn't cancel itself out.

Consider function f and g
f(x)=x^2+7x
g(x)=3x-1
what is the value of (f•g)(x)
9514 1404 393
Answer:
B. 9x² +15x -6
Step-by-step explanation:
The composition operator means that function f is applied to function g:
[tex](f\circ g)(x)=f(g(x))=f(3x-1)\\\\=(3x-1)^2+7(3x-1)\\\\=9x^2-6x+1+21x-7\\\\\boxed{(f\circ g)(x)=9x^2+15x-6}\qquad\textbf{matches B}[/tex]

?
In the slope-intercept form, which variable
represents the slope/measure of change?
Step-by-step explanation:
Hey there!
We know that the slope intercept is; y = mx+b.
Where "m" represents the slope. And "b" represents the y-intercept.
Example:
If the question is as; y = 3x +8
Then your slope of the slope intercept form is "3" where as "8" is y-intercept.
So, the variable"m" represents the slope.
Hope it helps...
