Make r the subject of the formula t=r/r-3
Answers
Answer:
[tex]r = \frac{3t}{t-1}[/tex]
Step-by-step explanation:
[tex]t = \frac{r}{r - 3}[/tex]
Cross multiply,
t(r - 3) = r
tr - 3t = r
tr = r + 3t
tr - r = 3t
r(t -1) = 3t
[tex]r = \frac{3t}{t-1}[/tex]
Answer:
r = 3t/(t - 1)
Step-by-step explanation:
t = r/(r - 3)
t(r - 3) = r
tr - 3t = r
tr = r + 3t
tr - r = 3t
r(t - 1) = 3t
r = 3t/(t - 1)
Evaluate h(8q2 - 2g) for h(x) = 7x+ 4q
Answers
Answer:
56q2 - 10q
Step-by-step explanation:
1. the function is given h(x) = 7x + 4q
2. we should put (8q2 - 2q) instead of x
3. we should write when x = 8q2 - 2q
then it will be h(8q2 - 2q)= 7(8q2 - 2q) + 4q
4. then we should multiply the elements in the bracket with 7 then it will be 56q2 - 14q + 4q
5. then we should substract -14q + 4q then it will be -10
6. and answer comes 56q2 - 10q

Find the total surface area of the
following square pyramid:
4 cm
6 cm
SA = [?] cm^2
Answers
Answer:
Lateral surface area= 48cm^2
Step-by-step explanation:
for anyone who needs the lateral surface area.
The total surface area of the square pyramid with a base side length of 6 cm and a slant height of 4 cm is 84 square centimeters.
We have,
Base side length (s) = 6 cm
Slant height (l) = 4 cm
Area of square = s²
Area of base = 6² = 36 cm²
A square pyramid has four triangular lateral faces with equal area.
The formula for the area of a triangle.
Area of triangle = 1/2 * base * height
Area of lateral surface of the triangle = 1/2 * 6 cm * 4 cm = 12 cm²
Total lateral area = 4 * 12 cm² = 48 cm²
Total surface area = Area of base + Total lateral area
Total surface area = 36 cm² + 48 cm²
Total surface area = 84 cm²
Therefore,
The total surface area of the square pyramid with a base side length of 6 cm and a slant height of 4 cm is 84 square centimeters.

Is f(x)=6x a direct variation
Answers
Answer:
[tex]f(x)=6x[/tex] is a direct variation.
Step-by-step explanation:
Given the function
[tex]f(x)=6x[/tex]
We have to determine whether the equation [tex]y=6x[/tex] is a direct variation or not.
As we know that in direction variation, y and x increase or decrease by the same factor by the formula
[tex]y=kx[/tex]
where 'k' is the constant of variation
Given the function
[tex]y=6x[/tex]
Here 6 is the constant of variation ∵ [tex]y=kx[/tex]
Also y and x increase and decrease by the same factor
For example,
when x=6, y = 6(x)=6(6)=36
when x=8, y = 6(x) = 6(8) = 48
Hence, when x increase, the y increases by the same factor.
Therefore, [tex]f(x)=6x[/tex] is a direct variation.
