Zach throws a ball upward so that it follows the equation
y= 16x^2 + 64 +5 where y is the height of the ball and x is time.
How many seconds will it take for the ball to hit the ground?
Hey there!
=> y= 16x^2 + 64 +5
Let's obtain a formula for x
=> y= 16x^2 + 64 +5
=> y=16x^2+69
=> y - 69 = 16x^2
=> y - 69/16 = x^2
=> y - 4.3125 = x^2
=> x = √y - 4.3125
=> x = y - 2.08

Which of the binomials below is a factor of this trinomial?
x^2 + 14x + 40
A. x + 4
B. x^2 + 4
C. x + 10
D. x - 9
Answer:
A , C
Step-by-step explanation:
x² + 14x + 40 = ( x + 4 )( x + 10 )
main formula: x² + ( a + b )x + ab = ( x + a )( x + b )
A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: y=ax+b a=-0.761 b=20.501 r^2=0.643204 r=0.802 Use this to predict the number of situps a person who watches 2 hours of TV can do ( to one decimal place )
Answer:
The number of situps is approximately 19
Step-by-step explanation:
Regression Line
A regression line is a line that best fits any given dataset in terms of having the smallest overall distance from the line to the points.
Regression lines are useful to forecast the behavior of the dependent variable.
We are given the statistics related to determining if there is a relationship between hours of TV watched per day (x) and the number of situps a person can do (y).
The line is given as follows:
y=-0.761x+20.501
The rest of the parameters can only be used as a reference to evaluate how good the line approaches the dataset.
Now use the line to predict the number of situps a person who watches x=2 hours of TV can do:
y=-0.761*2+20.501
y=19
The number of situps is approximately 19
You have just arranged for a $1,760,000 mortgage to finance the purchase of a large tract of land. The mortgage has an APR of 7.6 percent, and it calls for monthly payments over the next 25 years. However, the loan has an eight-year balloon payment, meaning that the loan must be paid off then. How big will the balloon payment be?
Answer:
$1,500,257.38
Step-by-step explanation:
The balloon payment will be the balance on the loan after 8 years worth of payments have been made. The normal payment amount is the value calculated for a 25-year loan. A spreadsheet, financial calculator, or app can simplify this for you. In the attached, we have used the financial functions available on a TI-84 calculator.
The normal monthly payment will be $13,120.94.
After 8 years, the remaining balance will be $1,500,257.38. This is the size of the balloon payment.
Write the equation of the line that goes through (-2,4) and (2,8)
You have a credit card that has a balance of $3850 at an APR of 13.99%. You plan to pay $300 each month in an effort to clear the debt quickly. How many months will it take you to pay off the balance?
Answer:
about 14 months
Step-by-step explanation:
Questions regarding loan payments, values, interest amounts, number of payments, and so on, are conveniently answered by the financial formulas available in many apps, calculators, and spreadsheets. Here, we want to solve for the number of payments.
__
The time-value-of-money app on a TI-84 calculator tells us the number of monthly payments is 13.98. It will take about 14 months to pay off the credit card balance.
__
Alternate solutions
You can also use a graphing calculator to find the time value needed in the amortization formula that corresponds to a monthly payment amount of $300 on a loan of $3850 at 13.99% interest compounded 12 times per year. This is shown in the second attachment.
The algebraic solution is a little messy, and involves logarithms, but you can solve it that way, too.
A = P(r/n)/(1 -(1 +r/n)^(-nt))
gives the monthly payment A on a loan of principal P at annual rate r compounded n times per year for t years. We want to find the value of nt for P=3850, A=300, r=0.1399, n=12.
Putting in the numbers, we get ...
300 = 3850(0.1399/12)/(1 -(1 +0.1399/12)^(-nt))
(1.011658333...)^(-nt) = 0.8503847222... . . . . isolate nt term
nt = -log(0.8503857222...)/log(1.011658333...) ≈ 13.982213...
3/4 divided by 1/5 and explaining please
Answer:
3.75 or 3 3/4
Step-by-step explanation
Ok the denominators aren't the same so were going to make them the same by them changing into the same number.
we can do thins by timesing 5 by 4=20 and 4 timesing by 5=20
So now that the denominators are the same we have to times 1 by 4 since it denominator was times by same thing with 3 except that only get times by 5.
1 x 4=4 and 3 x 5=15 so now our two fractions are 15/20 and 4/20
15 divided by 4=3.75 and there's our answer.
we get the .75 because it is 3 more so 3 4 x3 =12 that's where we get 3 and then there is 3 left and 3/4 of and 3/4=0.75 and then you combined them to make 3.75.
hope it helps have a great afternoon

A student solved the equation sin2x/cos x = 2, 0 ≤ x ≤ pi, and got pi/2. What was the student's error?
Answer:
Step-by-step explanation:
Albeit cosine is undefined at , this discontinuity is evitable by canceling terms. The expression is equivalent to , which is continuous for all . According to this result, the student did not make a mistake. Answer was correct.
Answer:
See below
Step-by-step explanation:
Since [tex]cos(\frac{\pi}{2})=0[/tex], the denominator will be 0, and the result would be indeterminate.
Do not read on if you do not understand Calculus
However, notice that [tex]\lim_{x \to \frac{\pi}{2}} \frac{sin(2x)}{cos(x)}=2[/tex] by L'Hopital's Rule:
[tex]\lim_{x \to \frac{\pi}{2}} \frac{sin(2x)}{cos(x)}\\\\\frac{2cos(2x)}{-sin(x)}\\ \\\frac{2cos(2(\frac{\pi}{2}))}{-sin(\frac{\pi}{2} )}\\\\\frac{2cos(\pi)}{-1}\\ \\\frac{-2}{-1}\\ \\2[/tex]
Below is a diagram of a rabbit tunnel in the shape of a triangular prism.
What is the volume of the tunnel?
Answer: 412.5cm cubed
Step-by-step explanation:
Volume of a prism: area of base ( in this case it’s the triangle) times the height
First: half x 90 x 120 = 165
Then times the height
So, 164 x 2.5 = 412.5
The volume of the given pyramid will be 1.35m³.
What is a pyramid?
Design or construction with a base that is a polygon and sides that are three or more triangles that come together at the top.
A pyramid is a 3D shape where 3 triangle comes and meet in such a way that the base side creates a triangle.
The volume of a pyramid is given by
Volume = (1/3)base²×height.
Volume = area of cross-section × length
Given,
Area of cross-section = area of the base (triangle)
Since the area of the triangle = (1/2)base×height
So,
Area of cross-section = (1/2)1.20×0.90 = 0.54 m²
So,
Volume of pyramid = 0.54 × 2.5 = 1.35 m³.
Hence " The volume of the given pyramid will be 1.35m³".
