Answer:
2.5secsStep-by-step explanation:
Given the height of the ball modeled by the equation h = -16t^2+ 100, where
h is the height
t is in seconds
We can find the time taken by the ball to reach the ground.
The ball reaches the ground when the height h = 0
Substitute h = 0 into the equation and find t;
0 = -16t^2+ 100
16t^2 = 100
t^2 = 100/16
t = √100/16
t = 10/4
t = 2.5secs
Hence the ball reaches the ground after 2.5secs

HELP 60 PTS Write ln〖(a^2 b^3)/cd〗 in expanded form. SHOW ALL WORK TO RECEIVE CREDIT.
Answer:
[tex]\frac{(a*a)(b*b*b)}{c*d}[/tex]
Step-by-step explanation:
[tex]\frac{a^{2} * b^{3}}{cd}[/tex]
A number to an exponent is the number times itself. A number to the "n"th power would be that number times itself "n" times.
This means that the fraction above could also be expressed as;
[tex]\frac{(a*a)(b*b*b)}{c*d}[/tex]
If these parameters, "a", "b", "c", and "d" are given a value, then one can solve this equation.
A rectangular auditorium seats 1855 people. The number of seats in each row exceeds the number of rows by 18. Find the number of seats in each row.
Answer:
53 seats per row
Step-by-step explanation:
Given that:
Capacity = 1855
Let number of rows = x
Hence, Number of seats per row = x + 18
The Area of auditorium = capacity
Area of rectangle = Length * width
1855 = x * (x + 18)
1855 = x² + 18x
x² + 18x - 1855 = 0
x² + 53x - 35x - 1855 = 0
x(x + 53) - 35(x + 53) = 0
(x - 35) = 0 or (x +53) = 0
x = 35 or x = - 53
Hence x = 35 ; (x can't be negative)
Number of seats per row = 35 + 18 = 53

Answer:
x = -9
Step-by-step explanation:
Applying midsegment theorem, we would have the following:
CB = ½(RT)
CB = x + 19
RT = x + 29
Plug in the values
x + 19 = ½(x + 29)
2(x + 19) = x + 29
2x + 38 = x + 29
Collect like terms
2x - x = -38 + 29
x = -9
Solve -3(3p - 6r)+12 where p = 3 and r = 2.
Answer:
21
Step-by-step explanation:
First we do the problem inside the (), 3 x p = 9, 6 x r = 12, 9 - 12 = -3.
Now we do the problem outside of the (), -3 x -3 equals 9 because 2 negatives make a positive. Then we add 9 to 12 to get 21 :D
I need help with this question! Will mark brainliest :)
Answer:
A. -1/5
B. 8 gallons
C. 75 miles driven
Step-by-step explanation:
Part A is essentially just asking for the slope, which is written as a fraction with the numerator being the number of units the line goes up/down and the denominator being the number of units the line goes left/right. Because the line is going down from left to right, the slope is negative. The slope is -1/5.
Part B can be answered by simply looking at the graph and seeing where the line is at above 175 miles, which is 8 gallons.
Part C can be answered in the same way as Part B, by looking at where the line is at when level with 12 gallons, which is 75 miles driven.

Write the explicit formula for the sequence shown below
3, -3, -9, -15
Answer:
[tex]a_{n}[/tex] = 9 - 6n
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = - 3 - 3 = - 9 - (- 3) = - 15 - (- 9) = - 6
This indicates the sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 3 and d = - 6 , thus
[tex]a_{n}[/tex] = 3 - 6(n - 1) = 3 - 6n + 6 = 9 - 6n

(5x +40x +
+ 40x+31) = (x+7)
Answer:
Step-by-step explanation:
5x + 40x + 40x + 31 = x + 7
85x + 31 = x + 7
Bringing like terms on one side
85x - x = 7 - 31
84x = - 24
x = - 24/84 = 2/7

Both roots of x^2 + Nx + 144 are equal to each other. Find all the possible values of N.
Answer:
N=+24,-24
Step-by-step explanation:
Well this is a quadratic equation and we can make further deductions using it's discriminant
b²-4ac=0
N²-4(1×144)=0
N²-576=0
N²=576
N=√576
N=+24,-24
The possible values of N are +24, and -24 if both roots of x² + Nx + 144 are equal to each other.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
It is given that:
The quadratic equation is:
x² + Nx + 144 = 0
Discriminant will be zero:
D = 0
b²-4ac=0
N²-4(1×144)=0
N²=576
N=√576
N=+24,-24
Thus, the possible values of N are +24, and -24 if both roots of x² + Nx + 144 are equal to each other.

You start a new job. After w weeks, you have (10w+110) dollars in your savings account and (36w+25) dollars in your checking account.
Answer:
(46w+135) dollars
Step-by-step explanation:
Given that,
Amount in savings account = (10w+110) dollars
Amount in checking amount = (36w+25) dollars
We need to find an expression that represents the total in both accounts. It is simply the sum of amount in the savings account and checking amount.
Sum = (10w+110) dollars + (36w+25) dollars
= (10w+36w) + (110+25)
= (46w+135) dollars
Hence, the required expression is (46w+135) dollars

What is the equation of a line that is parallel to -x + 3y = 6 and passes through the point (3, 5)?
Answer:
y = 1/3x + 4
Step-by-step explanation:
Make it into slope intercept form
3y = x + 6
y = 1/3x + 2
parallel = same slope
y = 1/3x + b, plug in (3,5)
5 = 1/3(3) + b, b = 4
y = 1/3x + 4
Sociologists have found that information spreads among a population at an exponential rate. How do you think this happens? Describe a piece of good news circulating through your circle of friends or family. How is this exponential?
Answer: Because people talk about important information
Step-by-step explanation: like a virus, information spreads like wildfire. But good news that has spread around my community is that we have a bunch of motivated people looking forward to feeding the homeless and create a homeless shelter to get back on their feet. Thanks to flyers, friends, and family enough money was raised to successfully build a homeless shelter.
