Answers
Answer:
10 times
Step-by-step explanation:
The value of the 7 in 70,048 is 70,000
The value of the 7 in 17,992 is 7,000.
If you divide 70,000 by 7,000, you get 10.
The first 7 is 10 times greater than the 2nd.
I hope this helps!
pls ❤ and mark brainliest pls!
Answer:10 times
Step-by-step explanation:
The value of 7 in 70,048 stands for 7 Ten thousand which is equal to 70,000
Also 7 in 17,992 stands for 7 thousand which is equal to 7,000
So we divide to know how much the lesser value is in the grater vale giving us
70,000/7,000 =10
Therefore, the value of 7 in 70,048 is 10 times than the value of 7 in 17,992

Answers
Answer:
Step-by-step explanation:
cos(2a) = cos^2(a) - sin^2(a)
cos(2a) = 2cos^(a) - 1
cos(2a) = 11/25
11/25 = 2 cos^(a) - 1 Add 1 to both sides
1 + 11/25 = 2 cos^2
25/25 + 11/25 = 2 cos^2(a)
36/25 = 2 cos^2 (a) Divide by 2
36/50 = cos^2 (a) Take the square root of both sides.
6/5*sqrt(2) = cos(a)
One is given the following:
[tex]cos(2A)=\frac{11}{25}[/tex]One is asked to prove the following:
[tex]cos(A)=\frac{6}{5\sqrt{2}}[/tex]In order to prove the statement above, one will need to use a trigonometric identity. In this case, the following identity is the most relevant in the proof.
[tex]cos(2a)=2cos^2(A)-1[/tex]
One can manipulate this identity to suit the needs of the given problem:
[tex]cos(2a)=2cos^2(A)-1[/tex]
[tex]cos(2a)+1=2cos^2(A)[/tex]
[tex]\frac{cos(2a)+1}{2}=cos^2(A)[/tex]
[tex]\sqrt{\frac{cos(2a)+1}{2}}=cos(A)[/tex]
Now substitute the given information into this identity,
[tex]cos(2A)=\frac{11}{25}[/tex]
[tex]\sqrt{\frac{cos(2a)+1}{2}}=cos(A)[/tex]
Substitute,
[tex]\sqrt{\frac{\frac{11}{25}+1}{2}}=cos(A)[/tex]
Simplify, remember, any number over itself equals (1) and, in order to add two fractions, they must have the same denominator.
[tex]\sqrt{\frac{\frac{11}{25}+1}{2}}=cos(A)[/tex]
[tex]\sqrt{\frac{\frac{11}{25}+\frac{25}{25}}{2}}=cos(A)[/tex]
[tex]\sqrt{\frac{\frac{36}{25}}{2}}=cos(A)[/tex]
[tex]\sqrt{\frac{18}{25}}=cos(A)[/tex]
[tex]\frac{3\sqrt{2}}{5}=cos(A)[/tex]
Manipulate so that it resembles the given information; remember, any number over itself is (1), multiplying an equation by (1) doesn't change it,
[tex]\frac{3\sqrt{2}}{5}=cos(A)[/tex]
[tex]\frac{3\sqrt{2}}{5}*\frac{\sqrt{2}}{\sqrt{2}}=cos(A)[/tex]
[tex]\frac{3\sqrt{2*2}}{5*\sqrt{2}}=cos(A)[/tex]

- a positive slope will be an increasing line (an uphill line)
- a negotiate slope will be a decreasing line (a downhill line)
- a zero slope will be a flat line (no incline or decline)
- an undefined slope fits with a line that doesn’t go left-to-right. It’ll be a vertical line.
For line 1 slope is negative, for line 2 slope is undefined, for line 3 slope is positive and for line 4 slope is zero.
What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
The slope of a line is a measure of its steepness and direction. To determine the sign of the slope, we need to look at the direction of the line:
If the line is slanting upwards from left to right, the slope is positive.If the line is slanting downwards from left to right, the slope is negative.If the line is vertical, the slope is undefined (since the denominator of the slope formula, which is the difference in x-coordinates, is zero).If the line is horizontal, the slope is zero (since the numerator of the slope formula, which is the difference in y-coordinates, is zero).Therefore, Lines 1, 2, and 4 have negative slopes, undefinable slopes for lines 2 and 3, and positive slopes for lines 3 and zero for lines 4.

What is the interest rate when you borrow $600 for 1 year and pay $45.00 interest?
Answers
Answer:
Im not certain but I think 7.5% If you get another answer which is different trust them not me if u get one which is the same it should be correct
The interest rate was 7.5% when borrowing $600 for one year and paying $45.00 interest.
What is the simple interest?Simple interest is defined as interest paid on the original principal and calculated with the following formula:
S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100.
We have been given data as:
Principal (P) = $600
Time (T) = 1 year
Simple interest = $45.00
⇒ Simple interest = P × R × T
Substitute the value of P, and T in the above formula, and solve for R
⇒ 45.00 = 600 × R × 1
⇒ 45.00 = 600R
⇒ R = 45.00/600
⇒ R = 0.075
⇒ R = 7.5/100
⇒ R = 7.5%
Therefore, the interest rate was 7.5%.

If two functions, f(x) and g(x), are inverse functions, what must the composition of f(g(x)) and g(f(x)) both equal?
A. 0
B. 1
C. f(x) = g(x)
D. x
Answers
==========================================================
Explanation:
The composition of the original function with its inverse will cancel out the operations to yield the input as the output.
Consider the example functions shown below
f(x) = x+5g(x) = x-5The first function adds 5 while the second function does the complete opposite and subtract 5. The two functions are inverses of each other.
We see that,
f(x) = x+5
f(g(x)) = g(x)+5
f(g(x)) = x-5+5
f(g(x)) = x
and you should find that g(f(x)) = x for similar steps.
No matter what the x input is, the output will be identical to the input.
For instance, if we plug in x = 7, then adding 5 to it gets us 12. Then undoing that operation to subtract 5 gets us back to 7 again. This is one example showing why both f(g(x)) and g(f(x)) both equal x, where f and g are inverses of each other.

The y intercept shows there should be a point at (0, -9) on the y axis.
From that point you can use the slope and go up 5 and over to the right 3 before plotting the next point. You can keep doing that in that direction and you can also go in the reverse by going down 5 and to the left 3 if necessary in the graph.
