Answer:
1.277s and 0.098s
Step-by-step explanation:
Given the height of the ball modelled by the equation
h(t) = -16t^2+22t+6, where;
t is the time in seconds
To calculate the time interval (in seconds) in which the height of the basketball is 8 feet, we will simply substitute h(t) = 8 into the expression and calculate t as shown;
8 = -16t^2+22t+6
Divide through by 2
4 = -8t^2+11t+3
-8t^2+11t+3-4 = 0
8t^2-11t+1 = 0
t = 11±√11²-4(8)/2(8)
t = 11±√121-32/16
t = 11±√89/16
t = 11±9.43/16
t = 11+9.43/16 and t = 11-9.43/16
t = 20.43/16 and t = 1.57/16
t = 1.277s and t = 0.098s
Hence the time interval to the nearest thousands are 1.277s and 0.098s

Answer:
x= 1 y= +10
Step-by-step explanation:
Answer:
1) y=3x+2 2) 11
Step-by-step explanation:
you can use the first y and x points to solve this.
fot the first one you cna do 4 times 3 to get 12 and then you add 2 to get 14.
you are trying to turn the x intot he y value.
For the second question, you can use the formula you just created int the first question to answer it, just plug in the numbers
y=3 times 3 +2=11
Does doubling the radius of a sphere double the surface area? Explain your reasoning using an example.
Answer:
yes
Step-by-step explanation:
because area of sphere equals =

Answer:
6x-2
Step-by-step explanation:
the side lengths are x+2, x+2, 2x-3 and 2x-3
(the other two are the same as the ones shown because it's a rectangle)
when you combine like terms you get 2x+4 and 4x-6
combine like terms again and you get 6x-2

For each of the following, use the given information/picture to write an equation in point-slope form. Just the ones that have the yellow highlight.
Answer:
4. y = -x + 8
9. y = 3/2x + 15
16. y = 1/2x -5
20. y = -3/5x + 16
13. y = -1/2x + 1
14. y = 3/4x - 2
Step-by-step explanation:
4. 5=3(-1)+b = 8
9. 6=-6(3/2)+b=15
16. [tex]\frac{1--2}{12-6} =\frac{3}{6} = \frac{1}{2}[/tex]
-2= (1/2)6 + b = -5
20. [tex]\frac{19-13}{-5-5}= -\frac{6}{10} =-\frac{3}{5}[/tex]
19 = -3/5(-5) + b = 16
selena paid $15.00 for 6 gallons of gasoline what was the price per gallon
Answer:
$2.50
Step-by-step explanation:
Is Selena paid $15 for 6 gallons and you want to find the price for one gallon, all you need to do is divide the price of 6 gallons ($15) by the number of gallons (6).
15/6 = 2.5. Your answer is $2.50. Hope this helps ^-^
Hu is installing a new window in his bedroom wall. He wants to center it horizontally. The window is 40 1/2 inches long, and the wall is 105 1/4 inches long. How far from each edge of the wall should Hu install the window? Type the number only, as a decimal or fraction. What is the answer?
Given :
Hu is installing a new window in his bedroom wall. He wants to center it horizontally.
The window is 40 1/2= 81/2 inches long, and the wall is 105 1/4= 421/4 inches long.
To Find :
How far from each edge of the wall should Hu install the window.
Solution :
Remaining size,
[tex]R = \dfrac{421}{4}-\dfrac{81}{2}\\\\R = \dfrac{259}{4}\ inches[/tex]
So, distance of the window form eah edge is [tex]\dfrac{R}{2}=\dfrac{259}{8}\ inches[/tex].
Hence, this is the required solution.

Hiker's Elevation 3,000 Hiking The scatter plot shows a hiker's elevation above sea level during a hike from the base to the top of a mountain. The equation of a trend line for the hiker's elevation is y=9.84x + 651, where x represents the number of minutes and y represents the hiker's elevation in feet. Use the equation of the trend line to estimate the hiker's elevation after 140 minutes.

Rebekah manages a yoga studio that charges each customer a one-time initial fee of $35and an additional fee of $12per class taken. Rebekah's goal is for each customer to spend at least $100 at the studio, and she wants to know the minimum number of classes a customer needs to take to meet that goal.
Answer:
Step-by-step explanation:
12 x 5 = 60 + 35 = 85, and we cannot go any higher without exceeding 100. However it would be different if it was a decimal. So for now the answer would be 5 classes added with the initial one time fee of 35 dollars.

Miss Sullivan owns a farm where she has a total of 28 birds and dogs the total number of legs on those animals is 70 how many dogs and how many birds are on the farm
Answer:
21 birds and 7 dogs
Step-by-step explanation:
Represent Birds with B and Dogs with D
[tex]B + D = 28[/tex] ----- Total Animals
A bird has 2 legs and a dog has 4, so:
[tex]2B + 4D = 70[/tex] ---- Legs
Required
Solve for D and B
Make D the subject in the first equation
[tex]D = 28 - B[/tex]
Substitute 28 - B for D in the second
[tex]2B + 4(28 - B) = 70[/tex]
[tex]2B + 112 - 4B = 70[/tex]
Collect Like Terms
[tex]2B - 4B = 70 - 112[/tex]
[tex]-2B = -42[/tex]
Solve for B
[tex]B = -42/-2[/tex]
[tex]B = 21[/tex]
Recall that: [tex]D = 28 - B[/tex]
[tex]D = 28 - 21[/tex]
[tex]D = 7[/tex]
Hence, there are 21 birds and 7 dogs

Help pls will mark brainliest
Answer:
2x^2 - 2x + 5
Step-by-step explanation:
so the south side is the bottom of the rectangle
you just add all the expressions given on the bottom which are
5x +2 , x^2 - 9 , x^2 - 7x + 12
so add 5x +2 + x^2 - 9 + x^2 - 7x + 12
add like terms and you get
2x^2 - 2x + 5
I hope that makes sense :)
Using the similar triangles, which equation could be used to find the slope of line AB?
A)slope=p/q
B)slope=q/p
C)slope=n/m
D)slope=q/n
Answer:
A) slope = p/q
Step-by-step explanation:
Slope of any given can be found using the formula, [tex] \frac{rise}{run} = \frac{y_2 - y_1}{x_2 - x_1} [/tex].
In this case, using similar triangles, the rise over the run of any of the given similar triangles will give us the slope of line AB.
This means, slope of line AB would be:
[tex] \frac{rise}{run} = \frac{m}{n} = \frac{p}{q}
[/tex].
✅Therefore, slope of line AB = p/q

Answer:
C
Step-by-step explanation:
The Pythagorean Theorem says [tex]a^{2} +b^{2} =c^{2}[/tex], with c being the hypothomes, which is not part of the right angle. So, when you square a and b, you get [tex]c^{2}[/tex]. To find the value of c, you find its square root.

UN PASTEL SE CORTA QUITANDO CADA VEZ LA TERCERA PARTE DEL PASTEL QUE HAY EN EL MOMENTO DE CORTAR ¿QUE FRACCION DEL PASTEL ORIGINAL QUEDO DESPUES DE CORTAR TRES VECES?
Answer:
No queda nada del pastel.
Step-by-step explanation:
El pastel representaria un entero, si al entero lo dividimos en tercios, son tres tercios los que los conforman, por ende si lo cortamos tres veces, en el primer corte quedarian dos tercios de pastel, en el segundo corte un tercio, y en el tercer corte el ultimo tercio , generando asi que no quede nada de este.
Los enteros se dividen en cuartos, tercios y hasta octavos, o muchas mas fracciones.
Un entero es equivalente a 4 porciones de 1/4 y a 3 porciones de 1/3

Answer:
Step-by-step explanation:
A and B are the side lengths. C is the hypotenuse (the longest side).
For triangle A)
a^2+b^2=c^2
(it won't let me add exponents but you get the point)
4^2+2^2=c^2
8+4=c^2
12=c^2
c=square root of 12
For B)
a^2+b^2=c^2
2^2+5^2=c^2
4+10=c^2
After solving, it doesnt
add up to 45

7-[tex]7=\frac{w}{4} -10[/tex]
Answer:
w = 68
Step-by-step explanation:
7 = w/4 - 10
~Simplify
7 = 1/4w - 10
~Add 10 to both sides
17 = 1/4w
~Multiply 4 to both sides
68 = w
