Answer:
A) x = 68.55
Step-by-step explanation:
The initial value of a function can be the value of the function when x = 0.
So we have a linear equation:
f(x) = a*x + b
with a slope of 10, then:
f(x) = 10*x + b
and we know that:
f(0) = 1 = 10*0 + b
1 = b
Then the linear function is:
f(x) = 10*x + 1
And we have an exponential function g(x)
A general expoential function is written as:
A*(r)^x
where r is the growth factor, here we know that it is equal to 1.1
Then:
g(x) = A*(1.1)^x
And we know that:
g(0) = 1, then:
A*(1.1)^0 = A*1 = 1
Then A = 1
g(x) = (1.1)^x
So our two functions are:
f(x) = 10*x + 1
g(x) = (1.1)^x
We want to find the value of x such that the exponential function's output exceeds the linear one. This is kinda hard to do analytically, so we can do it graphically.
Below you can see the graphs of both functions, where we can see that for x = 68.55, the exponential function's output exceeds the one of the linear function.
If we want to find the point analytically, we need to solve:
10*x + 1 = (1.1)^x
Which is a transcendental equation, which means that can not be solved in close form. So usually we solve them graphically.
Here we can also check that for the found value:
g(68.55) = (1.1)^68.55 = 687
f(68.55) = 10*68.55 + 1 = 685.6
So this is not the exact value at which g(x) overcomes f(x), but is a good approximation.

Answer:
3×81^x=9^{x+4}
since power of no is multiplied to its remaining power
3×3^4x=3^2{x+4}
if there is like terms then power is added
3^{1+4x}=3^{2x+8}
if there is like terms then power can be compared
so{1+4x}={2x+8}
1+4x=2x+8
4x-2x=8-1

Answer:
∠7 = 85°
Step-by-step explanation:
∠1 = 180 - 115 = 65° Because they are supplementary angles
∠2 = 180 - 65 - 85 = 30° Because the sum of all interior angles in a triangle
equals 180°
∠3 = 90° given
∠6 = 180 - 90 - 30 = 60° Because they are supplementary angles
∠4 = 180 - 155 = 25° Because they are supplementary angles
∠5 = 180 - 25 - 60 = 95° Because the sum of all interior angles in a
triangle equals 180°
∠7 = 180 - 95 = 85° Because they are supplementary angles

Step-by-step explanation:
a) Multiply the whole number 6 by the denominator 4. Whole number 6 equally 6 * 4/4
= 24/4
b) Add the answer from the previous step 24 to the numerator 3. New numerator is 24 + 3 = 27
c) Write a previous answer (new numerator 27) over the denominator 4.
Conversion a decimal number to a fraction: -11.5 = -115/10
= -23/2
a) Write down the decimal -11.5 divided by 1: -11.5 = -11.5/1
b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
-11.5/1
= -115/10
c) Simplify and reduce the fraction
-115/10
= -23 * 5/2*5
= -23 * 5/2*5
= -23/2

The denominator of the first term is a difference of squares, such that
4a ² - b ² = (2a)² - b ² = (2a - b) (2a + b)
So you can write the fractions as
(4a ² + b ²)/((2a - b) (2a + b)) - (2a - b)/(2a + b)
Multiply through the second fraction by 2a - b to get a common denominator:
(4a ² + b ²)/((2a - b) (2a + b)) - (2a - b)²/((2a + b) (2a - b))
((4a ² + b ²) - (2a - b)²) / ((2a - b) (2a + b))
Expand the numerator:
(4a ² + b ²) - (2a - b)²
(4a ² + b ²) - (4a ² - 4ab + b ²)
4ab
So the original expression reduces to
4ab / ((2a - b) (2a + b))
or
4ab / (4a ² - b ²)
upon condensing the denominator again.

Part B: b) 12x - 10 = 10x + 8
Part C: x = 9

Explanation:
B)
Since they're corresponding angles, they're equal to each other:
12x - 10 = 10x + 8
C)
12x - 10 = 10x + 8
2x = 18

9514 1404 393
Answer:
A. a
B. b
C. 9, 98, 82
Step-by-step explanation:
See attached.
"Corresponding" angles are those in the same direction from the point of intersection. Here, angles 1 and 3 are both northwest of the intersection point, so are corresponding.
From ...
12x -10 = 10x +8
2x = 18 . . . . . . . . . . . add 10-10x to both sides of the equation
x = 9 . . . . . . . divide by 2
Angles 1 and 3 are the same measure, so we choose the easier expression to evaluate mentally. Multiplying by 10 is easier than by 12, so we use 10·9+8=98 as the measure of angles 1 and 3. Angle 2 is the supplement of this.

B. 138°
C. 222°

Answer:
138°
Step-by-step explanation:
The measure of arc ABC is the measure of the corresponding central angle, ∠ANC. That angle is shown as 138°, so the measure of arc ABC is 138°.
Measure of an angle ABC is 111 degrees i.e. [tex]m[/tex]∠ABC = 111 degrees.
Angle subtended by an Arc of a circle-Theorem
The angle subtended by an arc at the center of the circle is double the angle subtended by the same arc at the circumference of the circle.
According to the given question
The angle subtended at the center of circle, i.e. ∠ANC = 138 degrees.
The exterior angle at the center is (360 - 138)degrees = 222 degrees
by angle subtended by an Arc of a circle theorem
[tex]m[/tex]∠ABC = [tex]\frac{222}{2}[/tex] [tex]= 111 degrees[/tex]
Hence, [tex]m[/tex]∠ABC = 111 degrees.

Step-by-step explanation:
As you have marked, the relevant sides are the adjacent side and the hypotenuse. The mnemonic SOH CAH TOA reminds you ...
Cos = Adjacent/Hypotenuse
For this triangle, that means ...
cos(43°) = (100 ft)/x
x = (100 ft)/cos(43°) . . . . . . . . . . multiply both sides by x/cos(43°)
x ≈ 136.73 ft
