Answer:
Width = 3 m
Step-by-step explanation:
Formula for perimeter:
P = l + w + l + w
Plug in what we know:
14 = 4 + w + 4 + w
Isolate variable w (width):
14 = 8 + 2w
6 = 2w
3 = w
Check your work:
14 = 4 + 3 + 4 + 3
14 = 7 + 7
14 = 14
Correct!

Find the unknown values of b and c in the equation y = -x² + bx + c given its vertex is (-7, -5).
Answers
Answer:
[tex] \displaystyle b = - 14[/tex]
[tex] \displaystyle c = - 54[/tex]
Step-by-step explanation:
to figure out b we can consider the following formula:
[tex] \displaystyle \frac{ - b}{2a} = h[/tex]
the form of vertex coordinate given by
[tex] \displaystyle (h,k)[/tex]
so according to the question
[tex] \displaystyle (h,k) = ( - 7, - 5)[/tex]
by order pair we obtain:
[tex] \displaystyle h = - 7, k = - 5[/tex]
now substitute the value of h and a to the formula:
[tex] \displaystyle \frac{ - b}{2(- 1)} = - 7[/tex]
simplify multiplication:
[tex] \displaystyle \frac{ - b}{ - 2} = - 7[/tex]
cross multiplication:
[tex] \displaystyle - b = 14[/tex]
divide both sides by -1:
[tex] \displaystyle b = - 14[/tex]
now we need to figure out C to do so substitute -7 for x and -5 for y which yields:
[tex] \displaystyle - {7}^{2} - 14( - 7) + c = - 5[/tex]
simplify square:
[tex] \displaystyle -49 - 14( - 7) + c = - 5[/tex]
simplify multiplication:
[tex] \displaystyle -49 + 98+ c = - 5[/tex]
simplify addition:
[tex] \displaystyle 49+ c = - 5[/tex]
cancel 49 from both sides:
[tex] \displaystyle c = - 54[/tex]
hence,
b=-14C=-54___________________________________
Problem:Find the unknown values of b and c in the equation y = -x² + bx + c given its vertex is (-7, -5).Let's Solve it!This is a problem where you want to able to ake use of tue Vertex Form in order to get the values of b and c fir the standard form of the parabola. Vertex (-7,-5) or (h,k) in the standard form. These are the x and y coordinates of the vertex. Note the standard form is:[tex]\quad\quad\quad\quad\tt{ a{x}^{2} + bx + c}[/tex]
Since we have the given of:[tex]\quad\quad\quad\quad\tt{ a \: = - 1}[/tex]
[tex]\quad\quad\quad\quad\tt{ h = - 7}[/tex]
[tex]\quad\quad\quad\quad\tt{ k \: = - 5}[/tex]
Note the vertex form is:[tex]\quad\quad\quad\quad\tt{y = a(x - h {)}^{2} } + k[/tex]
[tex]\quad\quad\quad\quad\tt{y = - 1(x - ( - 7) {)}^{2} } + ( - 5)[/tex]
[tex]\quad\quad\quad\quad\tt{y = - 1(x + 7 {)}^{2} } - 5[/tex]
[tex]\quad\quad\quad\quad\tt{ \boxed{y = - {x}^{2} - 14x - 54}}[/tex]
Hence, The answer for b and c is:[tex]\quad\quad\quad\quad\tt{ \boxed{ \boxed{ \color{magenta}{b = - 14}}}}[/tex]
[tex]\quad\quad\quad\quad\tt{ \boxed{ \boxed{ \color{magenta}{c = - 54}}}}[/tex]
Let's confirm it :You can use x coordinate of the vertex like this,[tex]\quad\quad\quad\quad\tt{ - 7 = \frac{b}{2(a)} }[/tex]
[tex]\quad\quad\quad\quad\tt{ - 7 = \frac{b}{2(-1)} }[/tex]
[tex]\quad\quad\quad\quad\tt{ - 7 = \frac{b}{-2} }[/tex]
[tex]\quad\quad\quad\quad\tt{ (- 2)( - 7) = - b }[/tex]
[tex]\quad\quad\quad\quad\tt{ \frac{ (- 2)( - 7)}{ - 1} = b }[/tex]
[tex]\quad\quad\quad\quad\tt{ \frac{ 14}{ - 1} = b }[/tex]
[tex]\quad\quad\quad\quad\tt{ \boxed{ - 14 = b }}[/tex]
You can also confirm the y coordinate of the vertex in the standard form by plugging the x coordinate.[tex]\quad\quad\quad\quad\tt{y = - {(-7)}^{2} - 14(-7) - 54}[/tex]
[tex]\quad\quad\quad\quad\tt{y = - 49 +98 - 54}[/tex]
[tex]\quad\quad\quad\quad\tt{y = - 49 +98 - 54}[/tex]
[tex]\quad\quad\quad\quad\tt{y = 49 - 54}[/tex]
[tex]\quad\quad\quad\quad\tt{ \boxed{y = - 5}}[/tex]
So, the final answer for b and c is:[tex]\quad\quad\quad\quad\tt\huge{ \boxed{ \boxed{ \color{magenta}{b = - 14}}}}[/tex]
[tex]\quad\quad\quad\quad\tt\huge{ \boxed{ \boxed{ \color{magenta}{c = - 54}}}}[/tex]

You purchase 2 action figures per week. You have 48 action figures, which is 75% of the total number of action figures you need to complete your collection. *also what does 2 mean in this equation*
Answers
Answer:
64
Step-by-step explanation: In order to find the amount of action figures needed to complete your collection, you divide 48 by 75%. This gives us 64. The reason we divide, is because of inverse operations. If we are going to find 75% of 48, you would multiply 48 by .75. Since this is the opposite, we must divide it.
Also, I'm not quite sure what the question is requesting by asking for what 2 represents. What is the specific skill you are learning in class? Maybe that'll help us figure it out.

Answers
Responder:
$ 16,2
Explicação passo a passo:
No dia da festa, Bianca comprou os pastéis por US $ 5,20, duas maçãs do amor por US $ 3,40 e dois refrigerantes por US $ 7,60. Quanto bianca você gastou?
O valor gasto por Bianca é a soma de todos os itens que ela comprou:
Pastelaria = $ 5,20
Maçãs do amor = $ 3,40
Refrigerantes = $ 7,60
A soma da soma dá o valor gasto de Bianca:
Doces + Maçãs do Amor + Refrigerante
$ (5,20 + 3,40 + 7,60)
= $ 16,2

Initial mass = 18 g
k-value = 0.1226
The mass at time t (days) is
At half life, m = 18/2 = 9 g.
The time for half life is given by
Therefore
ln(1/2) = -0.1226t
Hence obtain
t = ln(1/2) / -0.1226
= 5.654 days
Answer: 5.7 days (nearest tenth)

For this problem, we use the formula for radioactive decay which is expressed as follows:
An = Aoe^-kt
where An is the amount left after time t, Ao is the initial amount and k is a constant.
We calculate as follows:
A0 = 18
An = 18/2 = 9
k = 0.125
9 = 18 e^-0.125t
0.5 = e^-0.125t
t = 5.55 days

If I have 3 integers that are greater than -5, and less than or equal to 3. The median is -1, no Mode and range is 5, the mean is 0. Give the set of 3 numbers.
Answers
Answer:
{-2, -1 , 3}
Step-by-step explanation:
When we have a set like:
{x₁, x₂, x₃}
The mode is the value that appears the most, so if there is no mode, then each value appears just one time.
The median is the middle value, here we know that the median is -1, then we can rewrite the set as:
{x₁, -1 , x₃}
The mean is computed as:
Mean = (x₁ + x₂ + x₃)/3
in this case we know that the mean is 0, then:
0 = (x₁ + x₂ + x₃)/3
then the numerator must be zero, so:
0 = (x₁ + x₂ + x₃)
replacing the value of x₂ = -1 we get:
0 = (x₁ - 1 + x₃)
where:
-5 < x₁ < -1 < x₃ ≤ 3
Now we can select the values of x₁ and x₃ such that the sum is equal to zero, and it meets the wanted restrictions.
here we can choose x₃ to be equal to 3 (the maximum allowed value), I do this because I noticed that the other values that are larger than -1 will not work (just with quick math).
then:
0 = x₁ - 1 + 3
Now we can solve this for x₁
0 = x₁ + 2
-2 = x₁
Then the set is:
{-2, -1 , 3}
Renee has dimes and quarters in her wallet that total $1.60. She has 2 more dimes than quarters.
How many of each coin does Renee have?
Answers
Given:
Renee has dimes and quarters in her wallet that total $1.60.
She has 2 more dimes than quarters.
To find:
The number of each type of coins.
Solution:
Let x be the number of dimes and y be the number of quarters.
She has 2 more dimes than quarters. So,
[tex]x=y+2[/tex] ...(i)
We know that,
1 dime = $0.10
1 quarter = $0.25
Renee has dimes and quarters in her wallet that total $1.60. So,
[tex]0.10x+0.25y=1.60[/tex] ...(ii)
From (i) and (ii), we get
[tex]0.10(y+2)+0.25y=1.60[/tex]
[tex]0.10y+0.20+0.25y=1.60[/tex]
[tex]0.35y=1.60-0.20[/tex]
[tex]0.35y=1.40[/tex]
Divide both sides by 0.35.
[tex]y=\dfrac{1.40}{0.35}[/tex]
[tex]y=4[/tex]
Substituting [tex]y=4[/tex] in (i), we get
[tex]x=4+2[/tex]
[tex]x=6[/tex]
Therefore, the number of dimes is 6 and the number of quarters is 4.
