Shirts are on sale for 15% off. Fernando uses the expression p - 0.15p to find the
new price of a shirt that originally cost p dollars.
Complete each sentence.
Please!!
Answer:
The expression that represents the sale price of the shirt is p-0.15p.
Given that,
He wants to purchase the shirt i.e. on the sale for 15% off on the regular price.
The regular price should be p dollars.
Based on the above information, the equation should be p -0.15p
Here the shirt price should be multiplied with the discount and then subtract it.
Therefore we can conclude that the expression that represents the sale price of the shirt is p-0.15p.

_________
x < -5
On the number line, the values of x are on the left side of -5 where -5 is not included and this can be determined by simplifying the given inequality.
Given :
Inequality -- (x + 3 < -2)
The following steps can be used to graph the solution of the given inequality:
Step 1 - Write the given inequality.
x + 3 < -2
Step 2 - First, simplify the given inequality. Subtract 3 on both sides in the above inequality.
x + 3 - 3 < -2 - 3
x < -5
Step 3 - So, the interval of x is given by ([tex]-\infty[/tex], -5).
Step 4 - On the number line, the values of x are on the left side of -5 where -5 is not included.

The velocity function of a car is given by v(t) = -3t^2 + 18t + 9 m/s. Find the acceleration of the car three seconds before it comes to a stop.
A. a = -6.46 m/s²
B. a = -2.76 m/s²
C. a = -0.46 m/s²
D. a = 2.76 m/s²
The acceleration of the car three seconds before it comes to a stop is 0m/s²
Given the velocity function expressed as v(t) = -3t^2 + 18t + 9
Acceleration is the change in velocity of a body with respect to time.
a(t) = dv/dt
Differentiating the velocity with respect to time will give;
dv/dt = -6t + 18
a = -6t + 18
a = -3(6) + 18
a = -18 + 18
a = 0m/s²
Hence the acceleration of the car three seconds before it comes to a stop is 0m/s²

What is the equation of the line which is perpendicular to y = 2x + 2 and passes through the point (0, 6)?
Step-by-step explanation:
the slope of a line function is always the factor of x.
in our case : 2
it is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.
in our case (2 = 2/1) y increases by 2 for every x increase by 1.
now, the perpendicular slope simply changes x and y upside-down and flips the sign.
in our case it is : -1/2
so, the line function looks like
y = (-1/2)x + b
b is the y-intercept, and we get it by using the coordinates of the point as x and y
6 = (-1/2)×0 + b = b
the full line equation is
y = (-1/2)x + 6

A small start-up skateboard company projects that the cost per month of manufacturing x skateboards will be C(x)=30x+600, and the revenue per month from selling x skateboards will be r(x)=−x2+80x. Given that profit is revenue minus cost, for what value(s) of x will the company break even or make a profit?
9514 1404 393
Answer:
20 ≤ x ≤ 30
Step-by-step explanation:
The profit function is ...
profit = revenue - cost
= (-x^2 +80x) -(30x +600)
= -x^2 +50x -600
= -(x -20)(x -30)
The profit function will be positive where the signs of the factors are different: for x-values between 20 and 30. The profit function will be zero for x=20 and x=30.
The company will break even or make a profit for values of x that satisfy ...
