Step-by-step explanation:
[tex]log \frac{a}{b} = loga - logb[/tex]
logx - log3 = log(x-2)
[tex] log( \frac{x}{3} ) = log(x - 2)[/tex]
[tex] \frac{x}{3} = x - 2[/tex]
x = 3(x - 2)
x = .......
What is x?
(4/5)^x=64/125
Answer:
x = 3
Step-by-step explanation:
(4/5)^x = 64/125 means that 4^x / 5^x = 64/125
x can only be 3 because 4^3 = 64 and 5^3 = 125

Evaluate (-4)^(-2)..........................................................................................................
Answer:
[tex](-4)^{2} = \frac{1}{16}[/tex]
Step-by-step explanation:
Explanation:-
Given (-4)⁻²
we will apply (a)⁻ⁿ = [tex]\frac{1}{a^{n} }[/tex]
(-4)⁻² = [tex]\frac{1}{(-4)^{2} }[/tex]
[tex]= \frac{1}{(-1)^{2} (4)^{2} }[/tex]
[tex]= \frac{1}{16}[/tex]
[tex](-4)^{2} = \frac{1}{16}[/tex]

Step-by-step explanation:
Mariah has a spinner that has 10 equal sections, each containing a different number from 1 to 10. Mariah determines about how many times the spinner will land on a number that is greater than 7 in 250 spins, and her work is shown below.
P (number greater than 7) = StartFraction Number greater than 7 over Total number of sections EndFraction times number of spins = StartFraction 4 over 10 EndFraction (250) = 100.
What mistake did Mariah make, if any?
Mariah has the formula reversed; it should be the total number of sections over the numbers greater than 7.
Mariah should have used a 3 in the numerator because there are 3 numbers greater than 7.
Mariah should multiply by the number of sections in the spinner rather than the total number of spins.
Mariah calculated the prediction correctly and did not make any mistakes.
Answer:
Mariah should have used a 3 in the numerator because there are 3 numbers greater than 7.

1 Camelita nuns the track at her school that is of a milelong. If she runs 4. 3 miles, how many laps did she run?
Answer:
3 laps.
Step-by-step explanation:
Hi! I can see how this is tricky, but I was a bit confused by the 4 in "If she runs 4." It says in the problem that the track is a mile long... So if you run the track 3 times, 3 x 1 = 3.

Find the first 5 terms in the sequence...
Answer:
The first '5' terms of the given sequence
[tex]\frac{7}{2} , 4 ,\frac{9}{2} ,5,\frac{11}{2}[/tex]
Step-by-step explanation:
Explanation:-
Given that the [tex]n^{th}[/tex] aₙ = [tex]\frac{N}{2} + 3[/tex]
first term
Put n=1 ⇒ [tex]\frac{1}{2} + 3 = \frac{7}{2}[/tex]
second term
Put n=2 ⇒ [tex]\frac{2}{2} + 3 = 1+3=4[/tex]
Third term
Put n=3 ⇒ [tex]\frac{3}{2} + 3 = \frac{3+6}{2}=\frac{9}{2}[/tex]
Fourth term
Put n=4 ⇒ [tex]\frac{4}{2} + 3 = 2+3 =5[/tex]
Fifth term
Put n=5 ⇒ [tex]\frac{5}{2} + 3 = \frac{5+6}{2}=\frac{11}{2}[/tex]
The first '5' terms of the given sequence
[tex]\frac{7}{2} , 4 ,\frac{9}{2} ,5,\frac{11}{2}[/tex]

Find the length of side AB.
Give your answer to 3 significant figures.
с
410
13.5 cm
A
B
Answer:
AB ≈ 8.86 cm
Step-by-step explanation:
Using the sine ratio in the right triangle
sin41° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{13.5}[/tex] ( multiply both sides by 13.5 )
13.5 × sin41° = AB , then
AB ≈ 8,86 cm ( to 3 significant figures )
Answer:
8.87
Step-by-step explanation:
use the sin law for right triagles sin(θ)= opposite/hypotenuse so
sin(41)=(AB)/13.5
13.5×sin(41)=AB
8.87=AB
