Tim throws a stick straight up in the air from the ground. The function h = -16t^2+ 48t models the height, h, in feet, of
the stick above the ground after t seconds. Which inequality can be used to find the interval of time in which the stick
reaches a height of more than 8 feet?
Answer:
[tex]-2t^2+ 6t -1 > 0[/tex]
Step-by-step explanation:
Function Modeling
The height h in feet of the stick threw by Tim is modeled by the function:
[tex]h = -16t^2+ 48t[/tex]
where t is the time in seconds.
It's required to write an inequality that can be used to find the interval of time in which the stick reaches a height of more than 8 feet, i.e. h > 8.
Using the given model, we write the inequality:
[tex]-16t^2+ 48t > 8[/tex]
Dividing by 8
[tex]-2t^2+ 6t > 1[/tex]
Subtracting 1, we get the required inequality:
[tex]\mathbf{-2t^2+ 6t -1 > 0}[/tex]
Answer:
you want more than 8 feet so the answer would be -16t^2+48t>8
Step-by-step explanation:
h=-16t^2+48t
-16t62+48t>8
-16t^2+48t=8
divide both sides of the equal sighn by 8
-2t^2+6t=1
put the symbol back in
-2t^2+6t>1
substitute a random mumber for t
-2(5)^2+6(5)>1
-10^2+30>1
subtract 30 from both sides
100>-29
state is true so -16t62+48t>8 is the correct answer

Answer:
My answer is = 9 cannot equal 12. There are no variables present in this equation, so what are you solving for?
Step-by-step explanation:
On the right you would use distributive property and on the left you would just simply add and subtract.
However, you cannot equal it to zero either because there are no variables nor exponents.

Find the missing values.
Answer:
Below in bold.
Step-by-step explanation:
The 2 triangles are congruent and they are both isosceles.
So m < 3 = 54 degrees. (isosceles triangle)
m < 2 = 54 degrees. (congruent triangles)
m < 1 = 180 - 2(54)
= 180 - 108
= 72 degrees. (angles in a triangle sum to 180).
m < 4 = 72 degrees. (congruent triangles),
what is 55 - 11u =55

Slowhan decides to play a very fun game. He starts off with his favorite
odd integer. For every turn, Slowhan will either add 1 or subtract 1 to his current number.
What is the probability that after 11 turns, the resulting number will be odd?
Answer:
Answer is even on the 11th turn unless Slowhan is allowed to skip a turn.
Step-by-step explanation:
If you add or subtract every turn then every turn will always be the opposite of the last turn, so, it would be.
odd is 0
1 = even
2 = odd (You've seen here that every even numbers of turns how answer will be odd and when it is an odd number of turns it will be even)
3 = even
4 = odd
5 = even
6 = odd
7 = even
8 = odd
9 = even
10 = odd
11 = even
Solve the equation 7x-4(-4x-16)= -166
Answer: x = -10
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x= -10
Step-by-step explanation:
7x-4(-4x-16)=-166 foil the ()
7x+16x+64= -166 combine terms
23x+64= -166 subtract 64 to both sides
23x= -230 divide by 23
x= -10

Is this correct, i did 21.5 times 33.6 and converted it to yards to the nearest tenth and i got 80.3
Answer:
Thats what i got too :)
Step-by-step explanation:
You have the correct answer. It is 80.3 square yards.
Work Shown:
Area of parallelogram = length*width = 21.5*33.6 = 722.4 sq ft
1 yard = 3 ft
1 sq yd = 9 sq ft ... square both sides
To convert from square feet to square yards, we'll divide by 9
This is the same as multiplying by 1/9
722.4 sq ft = (722.4 sq ft)*(1 sq yd/9 sq ft)
722.4 sq ft = (722.4)*(1/9) sq yards
722.4 sq ft = 80.2667 sq yards
722.4 sq ft = 80.3 sq yards
40 percent of students in a class of 35 students are girls. how many girls are in this class?
Answer:
14 girls
Step-by-step explanation:
40% of 35 = [tex]\frac{40}{100}[/tex] × [tex]\frac{35}{1}[/tex] [tex]\frac{40}{100}[/tex] × [tex]\frac{35}{1} = \frac{1400}{100}[/tex] [tex]\frac{1400}{100} = \frac{14}{1} = 14[/tex]I hope this helps!
Answer:
14 girls in the class
Step-by-step explanation:
use percentage equation, p = nw or part of the question = the percentage times the total amount.
So in this case our p, or girls in the class (which is part of the total), is unknown. We have the percentage and we have the total. So all we need to do is multipy them. However how do you multiply percentage . . . well 40 percent also equalts to 0.40. So all you have to do is multiply .40 by 35 and you have your answer.

Is 11 a solution to 3(x+6)=4x ?
Answer:
The number 11 is not a solution for the given equation.
Step-by-step explanation:
We are given an equation with one variable. We can use simplifying processes to solve the equation.
[tex]3(x+6)=4x \ \ \text{Distribute the 3 through.}\\3x + 18 = 4x\ \ \ \text{Flip the equation.}\\4x = 3x + 18 \ \ \ \text{Subtract 3x from both sides.}\\\small\boxed{\bold{x = 18}}[/tex]
We can also substitute 11 for x and solve to see if the left side and right side of the equation equals itself.
[tex]3(11 + 6) = 4(11)\\33 + 18 = 44\\\small\boxed{\bold{51 \neq 44}}[/tex]
Therefore, 11 is not a solution for the given equation.
Answer:
First of all,We need to find the value of x to find that 11 is the solution to 3(x+6)=4x or not.[tex] \displaystyle \rm \longmapsto \:3(x + 6) = 4x[/tex]
[tex] \displaystyle \rm \longmapsto \:3x + 18 = 4x[/tex]
[tex] \displaystyle \rm \longmapsto \:4x = 3x + 18[/tex]
[tex] \displaystyle \rm \longmapsto \:4x - 3x = 18[/tex]
[tex] \displaystyle \rm \longmapsto \:x = 18[/tex]
Let's put x as 11:[tex] \displaystyle \rm \longmapsto \:3(11 + 6) = 4(11)[/tex]
[tex] \displaystyle \rm \longmapsto \:33 + 18 = 44[/tex]
[tex] \displaystyle \rm \longmapsto \:51 = 44[/tex]
51 doesn't equal to 44.So,11 is not the correct solution to 3(x+6)=4x.HELP Evaluate the function for x = 2 and x = 7.

is y=-2/5x inverse or direct variation
Answer:
direct
Step-by-step explanation:
The standard form of an equation representing direct variation is
y = kx ← k is the constant of variation
The standard form of an equation representing inverse variation is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
y = - [tex]\frac{2}{5}[/tex] x ← represents direct variation with k = - [tex]\frac{2}{5}[/tex]
