Answer:
x=(3,1/4)
Step-by-step explanation:
Be sure to use the formula...
[tex]-b + or - sqrt{b^{2} - 4ac } / 2a[/tex]
- First, move all variables to one side (left) of the equation. You want one side to be equivalent to zero.
-Next, you need to find a, b, and c. This should be...
a=4
b=-13
c=3
- Knowing this, fill in these variable to go along with the formula. I cannot do this for you, as you should try it on your own. But, you should end up with the solution x= (3,1/4).
- Hope this helps! If you need a further explanation or help on any more problems please let me know, as I would be glad to help anytime.

19.6 x 2 1/5 + (5.25 x 1 1/5 - 4.5 x 4/5
x=times
/= make fraction
the answer is 45.82
but i need the work on how to do it
Answer: Use order of operations (PEMDAS). Answer is 45.72.
Step-by-step explanation:
First, solve inside parenthesis:
(5.25*1 1/5 - 4.5*4/5)
Convert 1 1/5 into decimal. It will be easier. 1 1/5 is the same as 1.2
Do multiplication and division first.
5.25*1.2 = 6.3
Now it looks like: (6.3 - 4.5*4/5)
Convert 4/5 to a decimal: 4/5 = 0.8
(6.3 - 4.5*0.8)
Multiply 4.5*0.8 = 3.7
Subtract (6.3 - 3.7) = 2.6
Now the full equation is: 19.6*2 1/5 + (2.6)
2 1/5 as a decimal: 2.2
Multiply 19.6*2.2 = 43.12
Now the equation is: 43.12 + 2.6
Add 43.12 + 2.6 = 45.72
Which is the most reasonable estimate for 30% of 72?
A good estimate for 30% of 72 is 24, calculated by finding one-third of 72 or multiplying 10% of 72 by 3. This provides a reasonably close value quickly and without needing a calculator.
Estimating 30% of 72
To find a reasonable estimate for 30% of 72, we can use mental math to simplify the calculation. 30% is close to one-third, and for an estimate, one-third of 72 can be found by dividing 72 by 3, which gives us 24. Thus, a reasonable estimate for 30% of 72 is approximately 24. This is not an exact calculation, but it's a quick way to get a rough estimate that is easy to handle and useful for making plans that do not require precise amounts.
It's important to note that while certain percentages are easier to compute, such as 10% (simply move the decimal point one place to the left), 30% can be estimated by finding 10% of the number and then multiplying that by 3. Here, 10% of 72 is 7.2, and multiplying that by 3 gives 21.6, which rounds up to 22, slightly lower than our one-third estimate of 24.

The rectangle shown has length AC = 32, width
AE = 20, and B and F are midpoints of AC and AE , respectively. The area of quadrilateral ABDF is:
A. 320 B. 325 C. 330 D. 335 E. 340
Answer:
A. 320
Step-by-step explanation:
See attachment for the figure
in order to determine Area of quadrilateral ABDF, we'll use the formula i.e
Area of quadrilateral ABDF = Area of AECD - Area of ΔBCD - Area of ΔDEF ->eq(1)
whereas, area of AECD = (AC × AE)
Area of ΔBCD = 1/2 (BC x CD)
Area of ΔDEF =1/2 ( EF x ED)
Substituting in eq(1)
eq(1)=>
Area of quadrilateral ABDF = (AC × AE) - 1/2 (BC x CD)- 1/2 ( EF x ED)
=(32 x 20) - 1/2(16 x 20) - 1/2(10 x 32)
= 640 - 160 - 160
= 640 - 320
= 320 square unit
Therefore, the area of quadrilateral ABDF is 320 square unit

What are the exact solutions of x^2 − 3x − 7 = 0?
Given:
The given equation is [tex]x^{2} -3x-7=0[/tex]
We need to determine the exact solutions of the equation.
Exact solution:
The exact solution of the equation can be determined by solving the equation using quadratic formula,
[tex]x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}[/tex]
From the equation the values are a = 1, b = -3 and c = -7
Thus, substituting these values in the equation, we get;
[tex]x=\frac{-(-3) \pm \sqrt{3^2-4(1)(-7)}}{2(1)}[/tex]
[tex]x=\frac{3 \pm \sqrt{9+28}}{2}[/tex]
[tex]x=\frac{3 \pm \sqrt{37}}{2}[/tex]
Thus, the exact solutions of the given equation is [tex]x=\frac{3 \pm \sqrt{37}}{2}[/tex]
Hence, Option A is the correct answer.
You are
feet above the ground.
A circular carnival ride has a diameter of 120 ft. Suppose you board a gondola
at the bottom of the circular ride, which is 6 ft above the ground, and rotate
240° counterclockwise before the ride temporarily stops. How many feet
above ground are you when the ride stops?
stopping
position
starting position
(0,0)
Answer:
36 feet
Step-by-step explanation:
The diameter is 120 ft, which means the radius is 60 ft.
240° counterclockwise from the bottom of the circle is a standard angle of 150°.
The vertical position is therefore:
y = 6 + 60 sin 150°
y = 36
Answer: 96
Step-by-step explanation:
An object is launched straight into the air. The projectile motion of the object can be modeled using h(t) = 96t – 16t2, where t is the time since launch and h(t) is the height in feet of the projectile after time t in seconds.
Answer with Step-by-step explanation:
We are given that height of projectile after t seconds is given by
[tex]h(t)=96t-16t^2[/tex]
a.h(t)=144 ft
[tex]144=96t-16t^2[/tex]
[tex]16t^2-96t+144=0[/tex]
[tex]t^2-6t+9=0[/tex]
[tex]t^2-3t-3t+9=0[/tex]
[tex]t(t-3)-3(t-3)=0[/tex]
[tex](t-3)(t-3)=0[/tex]
t-3=0
t=3
After 3 s, the height of the project will be 144 feet in the air.
b.h(t)=0
[tex]96t-16t^2=0[/tex]
[tex]16t(6-t)=0[/tex]
[tex]16t=0\implies t=0[/tex]
[tex]6-t=0\implies t=6[/tex]
At t=0, the initial position of projectile
At t=6 s , the projectile will hit the ground.

find how long it takes (in seconds) for a car to travel when the car is going a speed of 20mph on a 100 foot track.
Answer:
3.4 seconds
Step-by-step explanation:
First, you have to change 20mph to feet per seconds. To do this, multiply mphs by 1.4667. When you multiply 20mph by 1.4667, you get 29.3333 fps.
Divide 100 by 29.333 to get 3.40909478 (3.4) seconds
Answer:
3.41 sec
Step-by-step explanation:
We need to use the formula: [tex]d=rt[/tex] , where r is the rate of the object, t is the time, and d is the distance.
Here, we know that the distance is 100 ft and that the rate is 20 mph. However, let's change the distance to miles because the rate is in miles.
There are 5280 ft in 1 mile, so:
5280/1 = 100/x ⇒ x = 100/5280
Then, d = 100/5280 miles and r = 20. Plug these in to find t:
100/5280 = 20t
t = (100/5280) / 20 hours
Now, we need to convert hours to seconds. There are 3600 seconds in 1 hour, so multiply our current t by 3600:
t = [(100/5280) / 20] * 3600 ≈ 3.41 sec

This table shows the length of the radius, in feet, of several circles.
Length (ft)
1/2 1/2 3/8 3 1/6 3 1/6
3 1/6 1/2 3/8 12 7 1 6
To create a line plot, hover over each number on the number line. Then click and drag up to plot the data.
Answer:
We cannot answer this question because there isn't a line plot for us to drag the data onto.
Create a line plot with radii lengths on the x-axis and frequency on the y-axis, connecting plotted points accordingly.
First, organize the data into a list or table format, with the lengths of the radii listed in feet:
1/2, 1/2, 3/8, 3 1/6, 3 1/6, 3 1/6, 1/2, 3/8, 12, 7 1/6
Next, you'll create a number line representing the lengths of the radii. You'll mark each length on the number line and then plot points above each mark corresponding to the frequency of each length.
For example:
- If there are two radii with a length of 1/2 foot, you'll plot two points above the mark for 1/2 on the number line.
- If there are three radii with a length of 3/8 foot, you'll plot three points above the mark for 3/8 on the number line.
- Similarly, for other lengths, mark and plot points accordingly.
Once you've plotted all the points, you'll connect them to form a line plot. The x-axis will represent the lengths of the radii, and the y-axis will represent the frequency of each length.

Chad ran a red light and hit another car. He decided to file a claim for damage
to his vehicle. Which deductible would he have to pay before he receives a
payment from the insurance company?
A. Comprehensive
B. Premium
C. Collision
D. He would not have to pay any deductible because he was not at
fault.
Answer:
Comprehensive deductible
Step-by-step explanation:
There is nothing called Premium deductible rather deductible determines how higher of lower a premium on a subject matter of insurance can be. Deductible is the amount with the insured have to bear at loss and any excess above the loss will be compensated by the insurance company.
Comprehensive deductible is the application to only to comprehensive insurance which was what Chad had on his motor vehicle. Comprehensive insurance covers majority of peril that happens to the insured vehicle. Therefore, comprehensive deductible is the deductible Chad has to bear himself before the insurance company take other losses upon theirself..
If he had $500 deductible on his car and total repair cost $700, then he will bear the $500 while the insurance company is entitled to pay only $200 as per policy statement.

Stefan, a 36-year-old male, bought a $150,000, 10-year life insurance policy from Fly-by-Night Life Insurance through his employer. Stefan paid weekly.
What is Stefan’s annual premium?
Explain how you found your answer and show all work for full credit.
Answer:
total annual cost = $682.50
Step-by-step explanation:
given data
Stefan age = 36 year
bought amount = $150,000
policy time period = 10 year
solution
we get here Stefan’s annual premium so here
policy for 10 year cost = $4.55 per thousand dollars
as given in attachment data
total amount of thousands of coverage will be
amount of thousands of coverage = [tex]\frac{150,000}{1,000}[/tex] = 150
and
total annual cost = 150 × $4.55
total annual cost = $682.50
Salma and coron broomall have reached an agreed upon price of $197,000. They plan to make a 30 percent down payment and finance the rest at 6 percent for 20 years. What is the monthly payment? What is the total amount to be paid?
Answer:
1. The monthly payment is $689.5
2. The total amount to be paid is
$224,580.
Step-by-step explanation:
Salsa and Corn Broom all reached an agreement upon the price of $197,000.
- The plan on making a 30 percent down payment. This implies that the will pay 0.3 × $197,000 = $59,100
This leaves them with
$197,000 - $59,100
= $137,900 to pay.
The plan on financing this remaining amount at 6 percent for 20 years.
This means they will pay
0.06 × $137,900 = $8,274 for 20 years. This translates to the payment of $8,274 × 20 = $165,480 across the 20 years.
1. The monthly payment is the yearly payment divided by 12.
Which is $8,274 ÷ 12 = $689.5
2. The total amount to be paid is
$165,480 + $59,100
= $224,580.

Step-by-step explanation:
reflect triangle a in the line y = 1
Answer:
(x , y) ---> (x , 2-y)
Step-by-step explanation:
Some examples:
(3,0) would map on to (3,2)
(3,1) would be unchanged after mapping
(3,-1) would map onto (3,3)
To reflect triangle A across the line y = 1, determine the corresponding points and apply symmetry properties. By understanding geometric transformations and symmetry, you can accurately visualize the new position of the triangle.
Reflecting triangle A in the line y = 1 involves transforming the triangle's position by flipping it over this horizontal line. This reflection will create a new image of the triangle across the line y = 1.
To reflect triangle A in y = 1, you need to locate the corresponding points across the line concerning their distance from the line itself. For instance, a point (x, y) would transform to (x, 2 - y) after reflection across y = 1.
Understanding symmetry properties and geometric transformations is crucial in reflecting shapes across lines, helping to visualize changes in position accurately.
