Answer:
A altura máxima é 5
Step-by-step explanation:
Matematicamente, a altura máxima pode ser obtida
A altura máxima é simplesmente o vértice da parábola
Começamos diferenciando a função Isso será -8x
Agora, defina -8x como 0
Isso significa que x = 0
Agora, substitua x = 0 de volta na equação temos
f (0) = -4 (0) ^ 2 + 5
f (0) = 5
A altura máxima é 5

14) Bill is looking to work at two different car dealerships. The Subaru dealership is going
to offer him a monthly pay of $1200 plus 4.5% of his total sales. His monthly sales can
be represented by x. The BMW dealership will give him a flat pay of $1600 monthly.
Use an inequality to show when it would be better for him to choose to work at Subaru
then BMW. Solve your inequality and determine the amount of sales he needs to make
in order for it to be a better choice to work at Subaru.
Answer:
1) $1,200 + x × 4.5/100 > $1,600
2) Bill has to make more than $8,888.[tex]\bar 8[/tex], in total sales monthly for it to be a better choice to work at Subaru
Step-by-step explanation:
1) The given parameters are;
The amount of monthly pay the Subaru dealership is offering = $1,200
The percentage of his total sales, x, Subaru dealership is offering = 4.5%
The flat monthly pay the BMW dealership is offering = $1,600
Therefore, the inequality to show when it would be better for him to choose to work for Subaru is given as follows;
$1,200 + x × 4.5/100 > $1,600
2) The solution of the above inequality is given as follows;
$1,200 + x × 4.5/100 > $1,600
x × 4.5/100 > $1,600 - $1,200
x × 4.5/100 > $400
x > $400 × 100/4.5 = $8,888.[tex]\bar 8[/tex]
Therefore, in order to make it better to work at Subaru, Bill has to sell more than $8,888.[tex]\bar 8[/tex] worth of cars every month.

Answer:
x = 6
Step-by-step explanation:
Use the exterior angle theorem, which states that the 2 opposite interior angles add up to the measure of the exterior angle.
Set up an equation:
(8x - 13) + (9x - 10) = 11x + 13
Add like terms and solve for x:
17x - 23 = 11x + 13
6x - 23 = 13
6x = 36
x = 6
So, x = 6

Find the degree measure of each angle in tbr triangle
Answer: ∠p = 85; ∠Q = 72; ∠R = 23
have: m∠P + m∠Q + m∠R = 180°
=> 4x - 7 + 3x + 3 + x = 180°
⇔ 8x - 4 = 180
⇔ x = (180 + 4)/8
⇔ x = 23
=> m∠P = 4.23 - 7 = 85°
m∠R = 23°
m∠Q = 3.23 + 3 = 72°

Bob is hiking down a 15-mile country trail. He could hike at 5 mph for the first 2 hours and then go the rest of the way at 3 mph or he could just go the whole way at 4 mph. How long would each of these options take? Which option is the faster?
Answer:
the fastest is starting at 5 mph then going three because it would take 3.66666666667 hours
Step-by-step explanation:
the 4mph would take 3.75 hour while the 5mph then 3mph only takes 3.666666667
Answer:
The First Option: 3 2/3 hours
The Second Option: 3 3/4 hours
The First Option is fastest.
Step-by-step explanation:
Option 1:First part- 5mph for 2 hours 5·2=10 (D=T·S)
15-10=5 because 15 is the total distance and 10 is the first part.(T=D/S)
Second part- 5/3= 1 2/3
5/3 because 5 is the distance left, and 3 is the speed. The time is 1 2/3 hours.
Option 2:4mph 15m (T=D/S)
15/4= 3 3/4 hours

What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, The temperature fell by 18 degrees Fahrenheit today.
Assuming the change in temperature is [tex]T_f[/tex] and initial temperature is [tex]T_i[/tex].
The tem[parature change can be represented by,
[tex]T_f = T_i - 18.[/tex]
Or - 18°F
Ali received 5 dollars, Assuming he had x dollars and after receiving he has now y dollars,
∴ The signed number represents this change.
y = x + 5.
Or + 5.
