The graph of a logarithmic function is shown below.
What is the domain of the function?
x < 0
x > 0
x < 1
all real numbers
Answers
Hope this helps!
Answer: The correct option is second, i.e., x>0.
Explanation:
As we know that the domain is the set of all possible inputs. If function is defined as, f(x) then all possible value of x for which the function f(x) is defined is called domain.
In a graph the domain is defined on the x axis and the range of the function is defined on y-axis.
In the given graph the function is defined from x=0 to [tex]x=\infty[/tex] because for [tex]x\leq 0[/tex] the graph is not defined. It means for [tex]x\leq 0[/tex] the function is not defined.
Sicen the graph is defined for all positive values of x, therefore the domain of the function is al real number greater than 0. It can be written as x>0 and the second option is correct.

In the diagram, △ABC ≅ △WRS. What is the perimeter of △WRS?
10 units
11 units
12 units
13 units
Answers
Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
△ABC ≅ △WRS
So, Perimeter of △ABC is given by
AB+BC+CA
here, AB = 3 units
BC = 4 units
AC = x
By pythagorus theorem, we get that
[tex]AC^2=AB^2+BC^2\\\\x^2=3^2+4^2\\\\x^2=9+16\\\\x^2=25\\\\x=\sqrt{25}\\\\x=5\ units[/tex]
So, perimeter of △ABC is
3+4+5=12 units
So, the perimeter of △WRS is also 12 units as they are similar triangles .
Hence, Third option is correct.

$2856
Answers
%60 of 1020 is:612
2040+612=2652
so third one is true
Answer:
Option (c) is correct.
He pays $ 2652.
Step-by-step explanation:
Given : Nial is signing a lease for an apartment that rents for $1020/month.
We have to find the amount he pay to move in if he must pay the first and last months' rent and a security deposit equal to 60% of his monthly rent.
Since, given he must pay the first and last months' rent and a security deposit equal to 60% of his monthly rent.
Given monthly rent is $ 1020
That is 60% of his monthly rent = [tex]\frac{60}{100}\times 1020=612[/tex]
Thus, total amount he needs to pay is first month rent + last month rent + 60% of his monthly rent.
That is 1020 + 1020 + 612 = 2652.
Thus, He pays $ 2652.
i need to know the equations
Answers
2l +3t +3b = 156 . . . . . . . 156 meals per day are supplied
l +t = 3b . . . . . . . . . . . . . . there are 3 times as many great cats as bears
l +t +b = 68 . . . . . . . . . . . there are a total of 68 animals
_____
The last 2 equations tell you
.. 4b = 68
.. b = 17
Subtracting 3 times the last equation from the first gives
.. -l = -48
There are 48 lions, 3 tigers, and 17 bears.
Let T = number of tigers
Let B = number of bears
If one lion eats 2 meals per day, then L number of lions eat 2L meals per day.
Tigers eat 3T meals per day, and bears eat 3B meals per day.
In one day, all animals combined ate 156 meals.
That gives us our first equation.
2L + 3T + 3B = 156
The lions and tigers are considered great cats. The bears are not cats.
There are 3 times as many great cats as bears.
This gives us our second equation.
L + T = 3B
In all there are 68 animals in the zoo.
From here we get our third equation.
L + T + B = 68
Our system of equations is:
2L + 3T + 3B = 156
L + T = 3B
L + T + B = 68
Now we solve the system of equations.
Subtract the second equation from the third equation.
B = -3B + 68
4B = 68
B = 17
Substitute B = 17 into the first and second equations.
2L + 3T + 3B = 156
2L + 3T + 3(17) = 156
2L + 3T + 51 = 156
2L + 3T = 105 New Equation A
L + T = 3B
L + T = 3(17)
L + T = 51 Equation B
Equations A and B have only two variables, so we can solve them as a system of two equations in two unknowns.
2L + 3T = 105
L + T = 51
Rewrite equation A. Multiply Equation B by -2 and write underneath Equation A. Then add the equations.
2L + 3T = 105
+ -2L - 2T = -102
-------------------------
T = 3
Now use B = 17 and T = 3 in the original third equation to solve for L.
L + T + B = 68
L + 3 + 17 = 68
L + 20 = 68
L = 48
Answer: There are 48 lions, 3 tigers, and 17 bears
Check:
"Lions eat 2 meals per day, tigers and bears eat 3 meals each per day."
Number of meals:
2 * 48 + 3 * 3 + 3 * 17 = 96 + 9 + 51 = 156
"There are 3 times as many great cats in the zoo as bears."
48 + 3 = 51, and 51 is 3 times 17
"There are 68 animals in the zoo."
48 + 3 + 17 = 68
All statements are satisfied by our solution, so the answer above is correct.
What is the equation of the line that is perpendicular to the line and passes through the point (6, 2)?
Answers
So, when you find something perpendicular, you are finding the opposite reciprocal.
The slope is 1/2 because:
y=mx+b <== it is in this form; m is equal to slope.
Flip the 2 and 1 and make it negative.
2/1= -2
We already know "C" and "D" aren't the options. Now, we can just plug in the points given to see if it works. Plug in the set of points (6,2)
y=-2x+14
2=-2(6)+14
2=-12+14
2=2 <== this works. This is our answer. Let's just make sure by checking the other one.
y=-2x-2
2=-2(6)-2
2=-12-2
2=-14 <== that is not true.
The first option is correct.

Describe how you would estimate the square root of a number that is not a perfect square without using a calculator. lets say n was the imperfect square number and the square root is w. the square root of n = n+w squared/ 2w.
Answers
√X =√S +(X-S)2√S
Where, X = the number you want the square roof of, and S is the closest square you know to x.
For example 75 is an imperfect square
Thus, X=75 and thus the nearest number S = 81, this ,means √81 =9.
Putting this into the formula;
√75= 9+(75-81)/2/2(9)
= 9 + -6/18
= 9-0.33333 = 8.667
= 8.667, thus the square root of 75 is 8.66

My jar has 25 dimes and some quarters, nickels, and pennies. The number of quarters plus dimes equals the number of pennies. I have 4 nickels for every dime and 2 pennies for every nickel. How many quarters are there? A. 175 B. 150 C. 125 D. 75
Answers
q = quarters
p = pennies
n = nickels
1. q + n = p
2. 4n = 1 d
3. 2p = 1n
1 d = 4n
25 d = x
x = 4 * 25 = 100 nickels
1 n = 2 p
100 n = x p
100 n = 200 p
q + n = p
There are 100 nickels. there are 200 pennies
q + 100 = 200
q = 200 - 100
q = 100
Answer
There are 100 quarters,<<<<======
Answer:
Quarters = 175
Step-by-step explanation:
Let the number of dimes in the jar = 25
number of Nickels = n
number of quarters = q
number of pennies = p
Now we will form the equation
Number of quarters plus dimes equal the number of pennies.
q + 25 = p --------(1)
You have 4 nickles for every dime
n = 4d
n = 4 × 25 = 100
and you have 2 pennies for every nickels
p = 2n
p = 2 × 100 = 200
Now we replace p = 200 in equation (1)
q + 25 = 200
q = 200 - 25
q = 175
Option A. 175 will be the answer.

In a hockey club there are 5% more boys than there are girls. If there is a total of
246 members in the club, what is the number of boys and the number of girls?
HOW WOULD I WORK THIS OUT
Answers
For an instance, pb stands for percentage of boys, and pg stands for percentage of girls.
pb + pg = 100%
There are 5% more boys, pb = pg + 5%
Input to the previous equation to find the percentage of the girls
pb + pg = 100%
pg + 5% + pg = 100%
2pg + 5% = 100%
2pg = 100% - 5%
2pg = 95%
--------------- divide each side by 2
pg = 47.5%
Substitute the percentage of girls to either equations to find the percentage of the boys
pb = pg + 5%
pb = 47.5% + 5%
pb = 52.5%
Find the number of the boys and the girls
The boys
b = pb × total members
b = 52.5% × 246
b = 0.525 × 246
b = 129.15
Because the number of people couldn't be a fraction, round to the nearest whole number
b = 129
The girls
g = total - b
g = 246 - 129
g = 117
There are 129 of boys, and 117 of girls
The number of boys and the number of girls are 126 and 120 respectively.
What is percentage?A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction.
Given that, there are 5% more boys than there are girls, there is a total of
246 members in the club,
We need to find the number of boys and the number of girls,
Here we will use the concept of percentage as well as equation solving,
Let the number of girls be x, so, the number of boys = 105% of x = 1.05x
According to the question,
x+1.05x = 246
2.05 x = 246
x = 120
1.05x = 126
Hence, the number of boys and the number of girls are 126 and 120 respectively.

Kelly is hanging shelves in her closet. She can buy shelves for $1.25 a foot. Kelly buys one 5-foot shelf and a shelf that measures 24 inches. The rest of her materials cost $90. How much change will she get it she pays with $100?
Answers
There are 12 inches in a foot.
Kelly buys two shelves that measure 7 feet altogether, and the cost of each foot is $1.25.
Multiply the number of feet by the cost per foot.
7 × 1.25 = 8.75
Add this to the cost of the rest of her items.
90 + 8.75 = 98.75
Finally, subtract this from the $100 Kelly will use to pay.
