Answer:
Equation is y = 1/2x + 1
Step-by-step explanation:
First off we know the slope, it is 1/2, so that is done already. Now we just need the y-intercept. In order to cross (4, 3), in needs to have a y-intercept of 1. So the equation is y = 1/2x + 1. I hope this helps, and I hope it's not wrong, but I don't think it is.
A healthy human heart beats about 1,533,000 times in a year. A sparrow's heart beats about
241,776,000 times in a year.
About how many times faster does the sparrow's heart beat compared to the human heart?
Estimate using a single digit times a power of 10.
2x108
or about 100 times faster
2x10
=1 x 102
0 2x10°
2x106
= 1 x 103
or about 1,000 times faster
2x108
2x105
=1 103
or about 1,000 times faster
2x109
2x105
=1 104
or about 10,000 times faster
Answer:
About 100 times faster
=1 x 10²
Step-by-step explanation:
Estimate using a single digit times a power of 10.
We approximate to the nearest whole number
A healthy human heart beats about 1,533,000 times in a year.
= 1.533 × 10⁶
As a single digit = 2.0 × 10⁶
A sparrow's heart beats about
241,776,000 times in a year.
= 2.41776 × 10⁸
As a single digit = 2 × 10⁸
About how many times faster does the sparrow's heart beat compared to the human heart?
We find the difference in their powers of 10
= ( 10^8 - 6)
= 10²
This means the sparrows heart beats at about
1 × 10² or a 100 times faster

Francis Watson's gross pay is $61,100. He takes a married exemption of $3,000. His state income tax rate is 3.5 percent. How much will be deducted from his weekly paycheck for state taxes?
Answer:
$39.10Step-by-step explanation:
in this problem we are expect to solve for the taxable income and return the tax deductible
given data
gross pay is $61,100
married exemption of $3,000.
the taxable gross pay is
$61,100- $3,000.
=$58100
the tax deductible is 3.5% of pay
=3.5/100*58100
=0.035*58100
=2033.5
since the $2033.5 is the annual tax, in a year we have 52 weeks
therefore
=2033.5/52
= $39.10
The formula for simple interest is where I is the amount you will pay in interest, r is the rate at which interest will accrue, P is the principal (amount borrowed), and m is the number of times the interest is applied.
Answer:
Kindly check explanation
Step-by-step explanation:
The simple interest formula (I) is the product of the principal, interest rate and the number of times interest is applied
Mathematically,
Simple interest (I) = principal(p) * rate(R) * time (t)
For instance, if a principal amount of $200 is borrowed at a rate of 5% per annum for 3 years. The simple interest on the amount borrowed will be :
Simple interest = $200 * 5% * 3
Simple Interest = $200 * 0.05 * 3
Simple Interest = $30

Use function notation to write G in terms of the parent function F.? F(x)=x^3 and g(x)=-(x+1)^3
Answer:hey
Step-by-step explanation:
G in terms of the parent function F is given as F(x) = -g(x-1).
What is a parent function?A parent function is the simplest function of the family of functions that preserves the definition of entire family.
Now the given functions are,
F(x) = x^3
g(x) = -(x+1)^3
We can see that g(x) is just an opposite of translation of 1 units to the right of F(x), to write g(x) in terms of F(x)
Then we can write,
g(x-1) = -(x-1+1)^3
or, g(x-1) = -x^3
or, g(x-1) = -F(x)
or, F(x) = -g(x-1)
Hence,G in terms of the parent function F is given as F(x) = -g(x-1).

Answer:
Here's how to subtract 3/4 from 7/8:
7
8
−
3
4
So we multiply 7 by 4, and get 28.
Then we multiply 3 by 8, and get 24.
Next we give both terms new denominators -- 8 × 4 = 32.
So now our fractions look like this:
28
32
−
24
32
Since our denominators match, we can subtract the numerators.
28 − 24 = 4
So the answer is:
0.284, is it right

Karen owns a seafood restaurant. She orders trout from an online retailer. Each pound of trout costs $30 and the company charges a $2 fee for shipping the order. However, if Karen orders 10 or more pounds, the Trout costs only &24 per pound, but the shipping fee is $6. Which piecewise function models the cost of x pounds of Trout?
Let, number of pounds of trout is x and their price is C.
For, x < 10 :
Price per pound is 30 .
C = 30x + 2 ....1 )
For, x ≥ 10 :
Price per pound is 24 .
C = 24x + 6 ....2 )
Therefore, total cost is :
[tex]C =\$ \left \{ {{30x+2 \ \ \ \ x<10} \atop {24x +6 \ \ \ \ x \ge 10}} \right.[/tex]
Hence, this is the required solution.
Answer:
30x+2, 0<x<10
24x+6, x≥10

Race day has finally arrived, and the event is about to begin. Each racer must complete one lap on the circular track, which has a radius of 15 meters. You find yourself racing against Ali Al Jouda! He holds the record for the KSAA U14 100m race. You are worried but motivated! According to his record, he runs at an average speed of 8.4 m/s. Your average speed is 7 m/s. How far will you have run by the time Ali crosses the finish line?
Answer:
78.54 meters
Step-by-step explanation:
circular path
radius = 15 meters
First we have to calculate the circumference of the circular path = 2[tex]\pi r[/tex]
= 2 * [tex]\pi * 15[/tex]
= 94.285 meters ( total distance to be covered )
For Ali running at a speed of 8.4 meters/ seconds
It will take him : ( 94.285 / 8.4 ) seconds
= 11.22 seconds
You running at a speed of 7 meters/seconds
hence at 11.22 seconds when Ali must have crossed the finish line you must have covered ;
(11.22 * 7 ) meters
= 78.54 meters
Jesus asked a group of students to choose their favorite type of movie. The results of the survey are shown in the graph. Based on the graph, how many students in class of 200 would be expected to choose comedy as their favorite movie?

The ratio of boys to girls in a group is 2:1. If there are 26 more boys than girls,
work out how many boys there are?
Answer:
26 girls are there
Step-by-step explanation:
2+1= 3- this is the number of parts the kids are divided into
2 - 1 = 1, in one part there are 26 extra boys
26/1=26- there are 26 boys and girls in one part
since there are an extra 26 boys, the boys have an extra part
boys-2 parts girls-1 part
since 1 part has 26 kids , and the boys have 2 parts u need to multiply, 2*26=52, 52 boys in the class
since the girls have 1 part and here are 26 kids in one part the # of girls in the class are 26
