try these.Evaluate the following logarithms.
Answer:
Reminder: [tex]log _a x[/tex] answers the question: "what power do I have to raise a to in order to get x?"
Thus said.
[tex]1. \ 64= 2^6 = 4^3 \implies log_464=3\\2. \ 5^1 = 5 \implies log_55 = 1\\3.\ 3^1=3; \ 2^1=2 \implies Log_33 + log_22 = 1+1=2\\4.\ 5^1=5; \ 8^1=8 \implies log_55 - log_88=1-1=0\\5. \ 8=2^3; 32=2^5 \implies log_28+log_232 = 3+5=8[/tex]
Last one, if you already talked about log properties, can be handled as:
[tex]log_28+log_232= log_2(8\times32) = log_2256 =8\ (256=2^8)[/tex]

Answer:
f(8)=10
Step-by-step explanation:
f(8) would mean x=8.
So you could replace x with 8 in the equation.
f(8)=8+2
=f(8)=10

(X+1)/4 = x/2
Answer:
1 = x
Step-by-step explanation:
First eliminate the fractions by multiplying both sides by the LCD, which is 4:
x + 1 = 2x
Subtracting x from both sides yields 1 = x

Given: SR is the perpendicular bisector of QT; QR is the perpendicular bisector of SP
Prove: PQ=TS
Two lines are said to be perpendicular if they are at right angle to each other. The prove that PQ = TS is as stated below:
SR ⊥ QT (given)
QR ⊥ PS (given)
Comparing Δ PQS and ΔQST, we have:
Points Q and T are equidistant to bisector SR (bisection property of a line)
Points P and S are equidistant from QR (bisection property of a line)
QS is a common side to the triangles
Then,
PS ≅ QT (similar property of triangles)
Thus,
PQ ≅ ST (Side-Side-Side (SSS) property of triangles)
Therefore by Side-Side-Side (SSS) theorem, PQ = ST.

Which value is equivalent to the expression 7^2 − 3^4?
A) -3^2
B) -1^9
C) 1^6
D) 3^2
Answer:
Option B
Step-by-step explanation:
Answer:
None of these are equal to the equation in question.
When solved 7^2 - 3^4 = -32
-3^2 = -9
-1^9 = -1
1^6 = 1
3^2 = 9
So none of the answer choices are equal to the equation in question.

- 8
Step-by-step explanation:
Evaluate g(- 64) then substitute the value obtained into f(x)
g(- 64) = [tex]\sqrt[3]{-64}[/tex] + 1 = - 4 + 1 = - 3 , then

Find the slope and the y−intercept of the line in the graph.
The slope is .
The y−intercept is .
Please be very specific
Very confused
Help please??
Answer:
Step-by-step explanation:
Using the slope-intercept form:
y=mx+bIn the equation y=mx+b, b is the coordinate on the y-axis where the graph crosses the y-axis and m denotes the slope of the line. The x and y represents all the (x, y) order pairs that graph points.
y=3x+4Substitute x for 0 to find the pair (0, Y). y=3(0)+4 Since 3 times 0 is 0, y will equal 4.
So put 4 under the 0.y=3(-1)+4 ⇒-1,1 y=1
y=3(0)+4 ⇒0,4 y=4
y=3(1)+4 ⇒ 1, 7 y=7
y=3(2)+4 ⇒ 2, 10 y=10
y=3(3)+4 ⇒ 3, 13 y=13
. Add the following. Answer in feet and inches. a) (3 ft. 8 in) + (4 ft. 9 in)
Answer:
8 ft. 5 in.
Step-by-step explanation:
First, let's change everything to inches
[] 3 ft. 8 in -> 3 * 12 = 36, 36 + 8 = 44 inches
[] 4 ft. 9 in -> 4 * 12 = 48, 48 + 9 = 57 inches
Now, we can add
44 + 57 = 101 inches
Last, we will simplify
101 -> 8 feet and 5 inches

Answer:
x = 21 and both sides are 53 units long
Step-by-step explanation:
They are congruent, so they are equal, so
3x-10=x+32 then solve for x
2x=42
x=21
then plug x into each side to get its length
3x-10=3(21)-10=53
x+32=21+32=53
You would expect them to be the same since they are congruent
