Answer:
[tex]y = 18 \times {7}^{x} [/tex]
Step-by-step explanation:
Using the formula for exponential function,
[tex]y = ab {}^{x} [/tex]
Let plug in 0,18.
[tex]18 = ab {}^{0} [/tex]
Using the zero power rule,
[tex]b {}^{0} = 1[/tex]
[tex]18 = a \times 1[/tex]
[tex]a = 18[/tex]
Since a equal 18 let plug in what we know so far
[tex]y = {18b}^{x} [/tex]
Now let find b.
Let use the other point, 3,6174
[tex]6174 = {18b}^{3} [/tex]
Divide 18 by both sides and we get
[tex]343 = b {}^{3} [/tex]
Take the 3rd root of 343
[tex] \sqrt[3]{343} = b = 7[/tex]
b=7
The equation is
[tex]y = 18 \times 7 {}^{x} [/tex]
help with algebra please
Answer:
b = -0.79
Step-by-step explanation:
b+ 2.77 over -2 = -1.78
multiply -2 on both sides to get
b + 2.77 = -3.56
subtract 2.77 on both sides to get
b = -0.79

feet per minute.
Bob's linear speed is higher than Jack's because the radius of the circle
around which Bob rotates is larger.
Responses:
Jack's linear speed is approximately 377 feet per minuteBob's linear speed is approximately 527.8 feet per minuteWhat is the relationship between linear speed and angular speed?Given:
The rotational speed of the merry go round = 6 revolution per minute
Jack's distance from the center = 10 feet
Bob's distance from the center = 14 feet
The angular speed, ω, of the merry-go-round is found as follows;
[tex]\omega = \mathbf{\dfrac{6 \times 2 \cdot \pi}{1 \ minute}} = 12 \cdot \pi \ rad/minute[/tex]Linear speed = ω × rWhich gives;
Jack's linear speed = 12·π rad/min × 10 feet ≈ 377 feet per minuteBob's linear speed = 12·π rad/min × 14 feet ≈ 527.8 feet per minuteLearn more about angular speed and linear speed here:

Find the inequality represented by the graph.
Answer:
y > 1/3 x - 3
Step-by-step explanation:
First, it would be easiest to find the equation of the line from the two integer points given, which are (0, -3) and (3, -2).
Find the change of y over the change of x to get the slope of the line.
(-2 - (-3))/(3 - 0) = 1/3
Since the line intercepts the y axis at (0, -3), the equation of the line would be
y = 1/3x - 3
We can see that the shaded portion is above the line, (and that the line is dotted) so this graph represents
y > 1/3 x - 3

If tan 2A = cot (A -18°), where 2A is an acute angle, find the value of A.
answer will be -24
A=-24
Answer:
A = 36
Step-by-step explanation:
Using the cofunction identity
tan(90 - x) = cotx
Given
tan2A = cot(A - 18) , then
90 - 2A = A - 18 ( add 2A to both sides )
90 = 3A - 18 ( add 18 to both sides )
108 = 3A ( divide both sides by 3 )
36 = A

The scale on a map is stated as
1:100 000
On the map, Jennifer estimates that the distance to her destination is 8 cm.
If she is correct in her estimate, how many kilometres is it to her destination?
9514 1404 393
Answer:
8 km
Step-by-step explanation:
The scale means the map distance of 8 cm translates to 800,000 cm in the real world. There are 100 cm in 1 m, and 1000 m in 1 km, so that distance is ...
800,000 cm = 8,000 m = 8 km
It is 8 km to Jennifer's destination.

Answer:
15.7 percent of 80 = 12.56
Step-by-step explanation:
Percentage solution with steps:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$80=100\%$
Step 4: Similarly, $x=15.7\%$.
Step 5: This results in a pair of simple equations:
$80=100\%(1)$.
$x=15.7\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{80}{x}=\frac{100\%}{15.7\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{80}=\frac{15.7}{100}$
$\Rightarrow x=12.56$
Therefore, $15.7\%$ of $80$ is $12.56$

Answer:
yearly cost for housing expenses = $11,400, average monthly cost for food = $650
yearly clothing cost = $900,
average monthly cost for transportation= $500,
Yearly cost for insurance & medical= $14,400
yearly cost for emergency fund = $600
average monthly college saving = $50
Step-by-step explanation:
Yearly housing = monthly cost * 12 = 950 * 12 = 11400
Food, monthly = 7800 /12 = 650
Clothing, yearly = 75 * 12 = $900
Monthly transport = 6000 / 12 = $500
Insurance and medical = 1200*12 =14400
Emergency fund = $50 * 12 = $600
College saving = $600 / 12 = $50
The sales tax on a $750 computer at J&M Computers is $48.75. What is the sales tax rate?
Answer:
Step-by-step explanation:
So 750 and 48.75
so tax is a percent of the whole or 750
750=100%
48.75=x%
750/100=48.75/x
solve for x
multiply both sides by x
750x/100=48.75
multiply both sides by 100
750x=4875
divide both sides by 750
x=6.5
the asnwe ris 6.5%
Can someone please help me please bro. Find the value of x and the length of each side. THIS IS DUED BY 10 o’clock tonight please help me out I don’t really understand it
9514 1404 393
Answer:
x = 2, y = 10, sides = 15
Step-by-step explanation:
The hash marks tell you all of the sides are the same length. You can use this fact to relate the side length expressions to each other to solve for the variables.
We see that x appears in the left and right expressions only. So we can find x by setting those expressions equal to each other.
8x -1 = 4x +7
4x = 8 . . . . . . . . . . . . . add 1-4x to both sides of the equation
x = 2 . . . . . . . . . . . . . . divide by 4; the value of x
8x -1 = 8(2) -1 = 15 . . . the length of the sides
Now, we can find y using an expression that involves y. The top expression is the simplest:
y +5 = 15 . . . . . the length of the side we just found
y = 10 . . . . . . . subtract 5
The variable values are ...
x = 2
y = 10
The side lengths are 15.

[tex]w {}^{ - 6} [/tex]
Using the product of power rule,
[tex] {x}^{a } \times x {}^{e} = x {}^{a + e} [/tex]
Then apply negative power rule
[tex]a {}^{ - x} = \frac{1}{a {}^{x} } [/tex]
