Answer:
[tex]b = 3[/tex]
The value of y triples
Step-by-step explanation:
Given:
[tex]\begin{array}{cccccc}x & {-2} & {-1} & {0} & {1} & {2} \ \\ y & {\frac{2}{9}} & {\frac{2}{3}} & {2} & {6} & {18} \ \end{array}[/tex]
Required
Determine b value
An exponential equation is:
[tex]y = ab^x[/tex]
When [tex]x = 0; y =2[/tex]
So:
[tex]y = ab^x[/tex]
[tex]2 = a * b^0[/tex]
[tex]2 = a[/tex]
[tex]a = 2[/tex]
When [tex]x = 2; y = 18[/tex]
So:
[tex]18 = a * b^2[/tex]
Substitute 2 for a
[tex]18 = 2 * b^2[/tex]
Divide by 2
[tex]9 = b^2[/tex]
Take positive square roots of both sides
[tex]3 = b[/tex]
[tex]b = 3[/tex]

Aiden and Haisem are going to eat the same amount of hamburgers and fries, but from different restaurants. Aiden goes to Burger King and spends $4.75. Each burger costs $1.25 and fries cost $0.50. Haisem spends $6.48 at McDonalods. Each burger costs $1.50 and fries cost $0.99. How many burgers and fries did Aiden and Haisem each buy?
Answer:
the burgers be 3 and fries be 2
Step-by-step explanation:
The computation is shown below:
Let us assume burgers be x
And, the fries be y
Now according to the questiojn
1.25x + 0.50y = $4.75
1.50x + 0.99y = $6.48
Now multiply by 1.2 in the first equation
1.50x + 0.6y = $5.70
1.50x + 0.99y = $6.48
-0.39y = -0.78
y = 2
Now put the value of y in any of the above equation
1.25x + 0.50(2) = $4.75
x = 3
Hence, the burgers be 3 and fries be 2
Simplify the expression:
10 + 10j – 9

A jet pilot flew a distance of 3,311 mi in 5 hour and 30 min. Find the planes average rate of speed. Please Help me! I would really appreciate it if someone helped me as soon as possible. Can you also explain how you got your answer?
Answer: 602 miles
Step-by-step explanation:
The average rate of speed is calculated by the formula;
= Distance / Time
You need to convert the time into hours. Time is 5 hours 30 mins.
Convert those minutes to hours:
1 hour is 60 minutes so 30 minutes would be:
= 30 / 60
= 0.5 hours
Total time = 5 hours + 0.5 hours
= 5.5 hours
Now go back to speed equation:
Speed = 3,311 / 5.5
= 602 miles

Find the radius of a circle with a circumference of 94.25ft
Answer: approximately 15
Step-by-step explanation:
Answer:
radius = 5.48ft
Step-by-step explanation:
The formula for the circumference of a circle is: C = πr² or pie times the radius squared.
Now that we know this, we can plug in the equation.
94.25 = πr²
÷π ÷π
30 = r²
√30 = √r²
5.48 = r
So, the radius of the circle is 5.48 ft
What are some real-world scenarios for the Pythagorean theorem?

y = -1/5x + 2/5
Write the standard equation of a circle with center (-2, -1) and radius 2.
Answer:
(x+2)^2+(y+1)^2=4
Step-by-step explanation:
(x-h)^2+(y-k)^2=r^2 is the standard equation for a circle
Plug in point at (h,k) Negative points= positive in equation due to (x-h),(y-k) All equal to radius squared
A salesperson earns a base salary of $32,500 per year plus a commission of 8% on total sales. Her total sales for one year were $450,000. Find the salesperson's total pay for the year.
The salesperson's total pay for the year is $68500
How to determine the total pay?The given parameters are:
Base pay = $32,500
Commission = 8%
Total Sales = $450,000
The total pay is calculated as:
Total = Base pay + Commission * Total Sales
This gives
Total = $32,500 + 8% * $450,000
Evaluate
Total = $68500
Hence, the salesperson's total pay for the year is $68500

Dots sells a total of 290 T-shirts ($2) and shorts ($4) . In April, total sales were $678. How many T-shirts and shorts did Dots sell?
Answer:
241 t-shirt and 49 short
Step-by-step explanation:
lets call shorts x and tshirts y
x+y=290 (first equation)
4x+2y=678 (second equation) { we multiply the price of short with the short so we can get the pieces sold and also with the t-shirt to get the pieces sold)
x=290-y
and substitute it with x in the second equation
4(290-y)+2y=678 then till u get to y=241 (the pieces sold)
290-241=49 (pieces sold)
so as proof 49+241=290 pieces sold
as proof also 4*49=196 price of all shorts sold
2*241=482 price of all t-shirts sold then add them together and u will get 196+482=678$

Describe the pattern, write the next term, and write a rule for the nth term of the sequence,
-15,-24,-33,-42
Please show work
Step-by-step explanation:
Next term is - 51
Use formula Tn=a+(n-1)d
a=the first term of the sequence which is - 15
d=the difference between the terms which is - 9
Substitute
Tn=-15+(n-1)(-9)
Tn=-15+9-9n
Tn=-9n-6
From this you will be able to generate all the terms in the pattern
If they say determine the 50th term just substitute 50 by n
Tn=-9(50)-6
Tn=-450-6
Tn=-456

Make circle open
You have the right idea but the endpoint is at the wrong location. Instead, the green dot should go at -1. The shading is to the right. We use a closed filled in circle here (instead of an open hole) to tell the reader "include the endpoint". So -1 is part of the solution set.
In short, the graph consists of a closed filled in circle at -1 with shading to the right. This visually describes all values that are larger than -1, or equal to -1.
