Answer:
Page 3 - the y-intercept would remain at 5 and the slope would be 3 times the upward slope.
Page 5 - the y-intercept would remain at -2 and the slope would be 1/4 instead of 5
Step-by-step explanation:
In point slope form the slope and y-intercept can be read directly from the equation.
y = mx + b where m is the slope and b is the y-intercept.

Answer:
r =√[3V/(π h)]
Step-by-step explanation:
V = ⅓ × π r²h
=> multiplied by 3
3V = π r² h
=> find r²
r² = 3V/(π h)
=> find r
r =√[3V/(π h)]
Answer:
[tex]r=\sqrt{\dfrac{3V}{\pi h}}[/tex]
Step-by-step explanation:
Given equation:
[tex]V=\dfrac{1}{3} \times \pi r^2 h[/tex]
To isolate [tex]r[/tex], multiply both sides by 3:
[tex]\implies V \times 3=\dfrac{1}{3} \times \pi r^2 h \times 3[/tex]
[tex]\implies 3V= \pi r^2 h[/tex]
Divide both sides by [tex]\pi h[/tex]:
[tex]\implies \dfrac{3V}{\pi h}= \dfrac{\pi r^2 h}{\pi h}[/tex]
[tex]\implies \dfrac{3V}{\pi h}=r^2[/tex]
Square root both sides:
[tex]\implies \sqrt{r^2}=\sqrt{\dfrac{3V}{\pi h}}[/tex]
As the radius is positive only:
[tex]\textsf{Apply radical rule} \quad \sqrt{a^2}=a, \quad a \geq 0[/tex]
[tex]\implies r=\sqrt{\dfrac{3V}{\pi h}}[/tex]

Given m = j^2 - 7p, find the value of j if
m = 18 and p = 9.
Answers
Answer:
9
Step-by-step explanation:
m = j^2 -7p
18 = j^2 -7(9)
18 = j^2 - 63
81 = j^2
√81 = √j^2
9 = j

? = 120, ? = 145, respectively
Step-by-step explanation:
? + 60 = 180
? (+ 60 - 60) = 180 - 60
? = 120
35 + ? = 180
(35 - 35) + ? = 180 - 35
? = 145
-16 + the quotient of a
number and -4 is -3
Answers
Answer:
76
Step-by-step explanation:
let the number be x
Then 16 + x/-4 = -3, so
x/-4 = -16-3 = -19 (add -16 on both sides)
x = -4*-19 = 76 (multiply by -4 on both sides)

Answer:
X (2, 1)
Y (2, 3)
W (5, 5)
Step-by-step explanation:
The current points are:
X (-2, -1)
Y (-2, -3)
W (-5, -5)
Now, after rotating 180 degrees around the origin, here is what points Y, Y, and W would look like:
X (2, 1)
Y (2, 3)
W (5, 5)
Plot these new points on the graph, and you'll have a new figure which will be rotated to 180 degrees.
I have also provided you with a graph, showing both, the original and the rotated version, below.
A, B & C form a triangle where Z BAC = 90°.
AB = 7.3 mm and CA = 4.6 mm.
Find the length of BC, giving your answer rounded to 1 DP.
Answers
Answer:
BC ≈ 8.6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle , that is
BC² = AB² + AC² = 7.3² + 4.6² = 53.29 + 21.16 = 74.45 ( square root both sides )
BC = [tex]\sqrt{74.45}[/tex] ≈ 8.6 ( to 1 dec. place )
