Answer:
[tex]2a - b -c[/tex]
Step-by-step explanation: We know that:
[tex]log_{2} 5 = a\\log_{2} 3 = b\\log_2 7 = c\\[/tex]
and we want:
[tex]log_2 \frac{25}{21}[/tex].
We can form the numerator using just the first fact (since 5^2 is 25) and the denominator using the latter two (since 3*7 = 21).
[tex]log_2 \frac{25}{21} = log_2 \frac{5^2}{3*7}.[/tex]
The logarithm of a division can be expanded by subtracting the numerator and denominator (while still keeping the log). The logarithm of a product can be expanded by adding the terms while keeping the log. If the logarithm is raised to a power, we can bring it down as a factor:
[tex]log_2 \frac{5^2}{3*7} = log_2(5)^2 - log_2 (3*7) = 2 log_2(5) - (log_2 3 + log_2 7)[/tex]
[tex]= 2 log_2(5) - log_2 3 - log_2 7[/tex] .
Substituting the variables:
[tex]2 log_2(5) - log_2 3 - log_2 7 = 2a - b - c[/tex]

Write the equation of a line with the given slope and y intercept.
m = 4
b = -2
Answer: y=4x-2
Step-by-step explanation:
Use the y=mx+b template to write the equation out. M is the slope which should be in front of x. This is why y=4x-2 is correct

Working together, two pumps can drain a certain pool in 6 hours. If it takes the older pump 15 hours to drain the pool by itself, how pump to drain the pool on its own?
Answer:
10
Step-by-step explanation:
Rate of drainage for pump A and B = [1 pool drained]/[6 hours]
Rate of drainage for pump A (older pump) = [1 pool drained]/[15 hours]
Rate for pump B (newer pump) = [1 pool drained]/[t hours]
Thus, adding the rate of drainage of A and B,
1/t + 1/15 = 1/6
t=10
PLEASE ANSWER ANY PROBLEM ASAP THANK YOU SO MUCH
Answer:
1) No
2) Yes
3) angle UXS = 120 degrees
4) arc CB = 40 degrees
Step-by-step explanation:
If AB is tangent to the circle, then angle at A would be 90 degrees.
1)
Is 13^2 + 14.6^2 = 19.4^2?
169 + 213.16 = 376.36 No
2)
Is 8^2 + 6^2 = 10^2?
64 + 36 = 100 Yes
3)
arc WS = arc VU + arc TU = 113 degrees
arc ST = arc WV because their chords cross making a pair of vertical angles.
full circle = 360 degrees
360-113 - 113 = 134 degrees
134/2 = 67 degrees for arc ST
arc STU = 67 + 53 = 120 degrees
Angle UXS = 120 degrees
4) arc CB = arc FB = 40 degrees because their chords cross making a pair of vertical angles.

Answer:
Hi,
In a square, all sides are equal.
The area is obtained by multiplying one side by another side.
So, A = L^2
A = Area
L = length of a side
24ft^2 = L^2
L = square root(24) = 4.9
L = 4.9
We can say x^2 = 24
And the length of one side is therefore 4.9
PLEASE ASAP HELP GIVING BRAINLIEST AND DOUBLE POINTS!!
Step-by-step explanation:
Given
Area of the cube (A) = 64 cm²
Now
The volume of the cube (V)
[tex]v \: = {a}^{ \frac{3}{2} } \\ v \: = 64 ^{ \frac{3}{2} } \\ v = 8 ^{ \frac{3 \times 2}{2} } \\ v \: = {8}^{3} \\ v = 512cm ^{3} [/tex]
Hope it will help :)❤
Answer:
512 cm³Step-by-step explanation:
Let us understand the letters in the formula first. The rest is really quite simple.
V = volume
A = area
Let's substitute the known area in for A
V = 64^3/2
Solve for V
64^3/2 = 512
V = 512
Hence, the volume of the cube is 512 cm³
