Answer:
g(x) = - 16x² + 100
Step-by-step explanation:
Given the model:
First drop:
h(x) = - 16x² + 4
Second drop hits the ground 2 seconds later
Function g(x) to model the second drop:
-16t² + V0t + h0
h(x) = - 16x² + 4
0 = - 16x² + 4
16x² = 4
x² = 4/16
x² = 1/4
x = 1/2
2 seconds later :
X = 1/2 + 2
x = 2.5
0 = - 16(2.5)² + 0 + h0
0 = - 100 + h0
h0 = 100
Hence,
g(x) = - 16x² + 100
Identify the value of y.
9-7y×7 = (6+5)-3y-416
pls help
Hey there!
Let's solve your equation step-by-step.
[tex]\fbox{9−7y(7)=6+5−3y−416}[/tex]
Step 1: Simplify both sides of the equation.
[tex]\fbox{9−7y(7)=6+5−3y−416}[/tex]
[tex]\fbox{9+−49y=6+5+−3y+−416}[/tex]
[tex]\fbox{−49y+9=(−3y)+(6+5+−416)}[/tex](Combine Like Terms)
[tex]\fbox{−49y+9=−3y+−405}[/tex]
[tex]\fbox{−49y+9=−3y−405}[/tex]
Step 2: Add 3y to both sides.
[tex]\fbox{−49y+9+3y=−3y−405+3y}[/tex]
[tex]\fbox{−46y+9=−405}[/tex]
Step 3: Subtract 9 from both sides.
[tex]\fbox{−46y+9−9=−405−9}[/tex]
[tex]\fbox{−46y=−414}[/tex]
Step 4: Divide both sides by -46.
[tex]\fbox{−46y/−46 = −414/−46}[/tex]
[tex]\fbox{y=9}[/tex]
Answer:
[tex]\fbox{y=\fbox{9}}[/tex]

3) Use the diagram to help you answer the question below.
Rational numbers
Integers
-88
-10.1
-191
Whole numbers
22
Which of the following is both a rational number and a whole number?
-88
-10.1
-191
22
Answer:
The number that both a rational number and a whole number is 22
Step-by-step explanation:
The whole numbers are the non-negative integers
Whole numbers ∈ the set of IntegersWhole numbers ∈ the set of Rational numbersThe integers are rational numbers with denominators 1
Integers ∈ the set of Rational numbersThe rational numbers are the numbers that can be written in the form of [tex]\frac{a}{b}[/tex] ,
b ≠ 0
Let us study the numbers in the figure:
The set of whole numbers ⊂ the set of integers ⊂ the set of rational numbers
∵ 22 ∈ the set of whole numbers
∴ 22 is a whole number
∴ 22 is a whole number and an integer
∴ 22 is a whole number, an integer, and a rational number
The set of integers ⊂ the set of rational
∵ -88 and -191 ∈ the set of integers
∴ -88 and -191 are integers
∴ -88 and -191 are integers and rational numbers
∵ -10.1 ∈ The set of rational numbers
∴ -10.1 is a rational number
Let us answer the question
→ We need to find a number that is a rational number and a whole number,
which means it must ∈ to the set of the whole numbers
∵ We only have one number ∈ the set of whole numbers, it is 22
∴ The number that both a rational number and a whole number is 22
Explain what the inequality --4h <-14 represents.
What value of h makes the equation true
Answer:
-4h < - 14
We solve for h by applying the inverse operations;
The inverse operation of multiplication is division, so we divide by -4 on both sides;
/-4 /-4
h < 3.5, it could be 3.4, 3.3, 3.2 3.123, 2.4, 2.576, there are tons of numbers below 3.5.
So anything below 3.5 would best be suitable for the equation.

Step-by-step explanation:
what is the geometrick mean of 27 and 8 with the pothagereom theorem
Answer:
x = 6√6
Step-by-step explanation:
27/x = x/8
x² = 27 × 8
x = √(27 × 8)
x = √(9 × 4 × 6)
x = 3 × 2 × √6
x = 6√6
Answer:
The geometric mean of 27 and 8 is [tex]6\sqrt{6}[/tex] or about 14.697
Step-by-step explanation:
The geometric mean is [tex]( \prod_{i=1}^{n} x_{i})^{\frac{1}{n}}=\sqrt[n]{x_1x_2 \cdot\: \cdot \:\cdot x_n}[/tex] where [tex]n[/tex] is the number of values and [tex]x_i[/tex] are the values to average. Thus, your geometric mean is [tex]\sqrt{27*8}=\sqrt{216}=6\sqrt{6}\approx14.697[/tex]

How many solutions does this equation have: y=-2x^2+5x-9
Step-by-step explanation:
First we solve it.
I'll use substitution.
In the first equation y equals -2x+2 so we can apply that to the second equation
2y + 4x = 4
2(-2x+2) + 4x = 4
distribute
-4x+4+4x=4
simplify
4=4
To figure out how many solutions it has:
•If both side of the equal sign are exactly the same: Infinitely many
ex: 6x=6x
•If both sides of the equal sign do not match when completely simplified: No solutions
ex: 3x=-5x
•If it creates an equation: 1 solution
ex: x=3+2y
Since both sides of the equal sign are 4, we have infinitely many solutions.

Hello Guys, I really need help with these questions. Here they are.
Solve each absolute value inequality and show its solution set.
(a) |x|<7
(b) |x+3|<9
(c) |y-8|>11
(g) |3x-1| greater or equal to 18
|4y+3| less than or equal to 13
Please help me with these. WIll give 20 pts. I will award brainly for the best answer!
Step-by-step explanation:
Ok, so first...
a) if x is positive, it will remain x, so *x<7*
b) if x+3 is positive, it will be x+3<9 but you have to simplify it so you subtract 3 on both sides and get *x<6*
c) if y-8 is positive, it will stay like that, and you then add 8 on both sides to get *y>19*
g) if 3x-1 is positive, it will be 3x-1 greater than or equal to 18. add 1 on both sides and *3x > or = to 18*
4y+3 < or = 13. subtract 3 on both sides and you get *4y < or = 13*

Less than or equal to is a '<' with a line underneath.

Answer:
x = 25
Step-by-step explanation:
The sum of the three interior angles of a triangle is always 180°.
4x + 2x + 30 = 180
6x + 30 = 180
6x = 150
x = 25
Answer:
sum of the interior angles of a triangle =180
2× + 4× + 30=180
6× + 30= 180
6× + 30 = 180
6× = 180-30
6× =150
6×/6=150/6
×= 25

A submarine is 37 meters below sea level. The submarine goes up 12 meters and
then descends(down) 40 meters. What is the submarine's new position relative to sea
level?
Answer:
65 meters below sea level
Step-by-step explanation:
so we can do one of 2 things, either 37-12+40, or -30+12-40, either way will give you the 65, just one will be a negative. obviously the submarine is going down, so if you do the positive way, just remember that it is negative.

Two trains left a station at the same time. Train A traveled north at a certain speed and train B traveled south
at twice that speed. After 4 hours, the trains were 600 miles apart. How fast was each train traveling?
Train A was traveling
mph... (hint... this is the slower train)
Train B was traveling
mph.
Step-by-step explanation:
Train 1 speed be 'u'
Train 2 speed be 'v'
And v=2u
Speed=distance/time
Trains going in opposite directions
Relative speed= v-u (as train 1 I slower than train 2)
v-u=600/4
2u-u=150
u=150miles/hour
v=300miles/hour
