The zeros are the initial point represent how have not yet started the hour of tutoring which means no total profit.(0,0)
What is the value of x?
O 2 units
O 3 units
O 5 units
08 units
Answer:
The value of x is 5 units ⇒ C
Step-by-step explanation:
In the given figure
∵ Δ ABC is a right triangle at vertex B
∵ AC is its hypotenuse
∵ BD ⊥ AC
∴ (BD)² = AD × DC
∵ BD = 10 units
∵ AD = x units
∵ DC = 4x units
→ Substitute them in the rule above
∴ (10)² = x × 4x
∴ 100 = 4x²
→ Divide both sides by 4
∵ [tex]\frac{100}{4}[/tex] = [tex]\frac{4x^{2}}{4}[/tex]
∴ 25 = x²
→ Take √ for both sides
∴ 5 = x
∴ The value of x is 5 units
The football coach threw a football from a platform to his
quarterback below. The height of the football, h, at time t seconds is modeled by the equation h(t) = -16t^2 + 28t + 15.
1. What is the maximum height of the ball?
2. If the quarterback caught the ball at a height of 6 feet, how many seconds was the ball in the air?
3. Give the domain and range of the function.
Answer:
1)27.25 feet
2)-0.2774,2.027
3)Domain = All real numbers
Range = y∈R : [tex]y \leq \frac{109}{4}[/tex]
Step-by-step explanation:
The height of the football, h, at time t seconds is modeled by the equation [tex]h(t) = -16t^2 + 28t + 15[/tex]
General quadratic equation : [tex]ax^2=bx+c=0[/tex]
1) Maximum height will be at [tex]\frac{-b}{2a}=\frac{-28}{2(-16)}=\frac{7}{8}[/tex]
To find maximum height Substitute [tex]t = \frac{7}{8}[/tex] in the given equation
[tex]h(t)=-16(\frac{7}{8})^2+28(\frac{7}{8})+15\\h(t)=27.25 feet[/tex]
2)
Substitute h(t)=6
So, [tex]-16t^2+28t+15=6[/tex]
[tex]-16t^2+28t+9=0\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\t=\frac{-28\pm \sqrt{28^2-4(-16)(9)}}{2(-16)}\\t=\frac{-28+ \sqrt{28^2-4(-16)(9)}}{2(-16)},\frac{-28- \sqrt{28^2-4(-16)(9)}}{2(-16)}\\t=-0.2774,2.027[/tex]
3)
Domain = All real numbers
Range = y∈R : [tex]y \leq \frac{109}{4}[/tex]
A shoe store buys a pair of boots from a supplier for $45. The store's manager decides on a markup of 35%. What is the new price of the boots?
Answer:
The new price of the books = $60.75
Step-by-step explanation:
As the original price is: $45As the markup is: 35% = 35/100 = 0.35
The Markup on the original price is:
0.35 × 45 = $15.75
Hence, the new price of the boots:
$45 + $15.75 = $60.75
Therefore, the new price of the books = $60.75
228:4 as a unit rate
Step-by-step explanation: 228/4 = 57, so 57/1 = 57:1.
Answer:
57: 1
Step-by-step explanation:
You take 228 divided by 4 which will give you 57 you do it to this side so you did the same thing to the other which mean you take 4 divided by 4 which is 1 therefore the unit rate is 57: 1

Find the slope-intercept equation of the line that passes through (3,-1) and has an undefined slope
Answer:
Slope intercept equation would be: x - 3 = 0
Step-by-step explanation:
[tex]slope \: (m) = undefined = \frac{1}{0} \\ \\ \because \: line \: passes \: through \: the \: \\ point (3, \: - 1) = ( x_{1}, \: y_{1}) \\ \\ equation \: of \: line \: line \: in \: \\ point \: slope \: form \: is : \\ \\ y - y_{1} = m(x - x_{1}) \\ \\ y - ( - 1) = \frac{1}{0} (x - 3) \\ \\ y + 1 = \frac{1}{0} (x - 3)\\ \\ 0(y + 1) = (x - 3) \\ \\ 0 = x - 3 \\ \\ x = 3[/tex]
x=3 is the slope-intercept equation of the line that passes through (3,-1) and has an undefined slope.
If a line has an undefined slope, it means the line is vertical.
A vertical line has the equation of the form x = c, where c is a constant representing the x-coordinate of any point on the line.
The line passes through the point (3, -1), so the x-coordinate of any point on the line is 3.
Therefore, the equation of the line is x = 3.
If the slope-intercept form of a line (y = mx + b), it's not possible for a vertical line because it doesn't have a slope.
The slope-intercept form assumes a non-vertical line.
Hence, the equation of the line passing through (3, -1) with an undefined slope is simply x = 3.

A novelist can write 2and 1 fourth pages in 3 fourths hour. How many pages can she write per hour?
Answer:
The novelist can write 3 pages per hour
Step-by-step explanation:
Unit rate is the work done per unit time.
Given
Number of pages = p = [tex]2\frac{1}{4} = \frac{9}{4}[/tex] pages
Time =t = [tex]\frac{3}{4}[/tex] hours
In order to find the number of pages per hour, we have to divide the number of pages by hours.
So,
[tex]Pager\ per\ hour = \frac{\frac{9}{4}}{\frac{3}{4}}\\Using\ \frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a}{b} * \frac{d}{c}\\pages\ per\ hour = \frac{9}{4} * \frac{4}{3}\\= 3\ pager\ per\ hour[/tex]
Hence,
The novelist can write 3 pages per hour

Describe in words and symbols the end behavior of f(x)=−5x4
Answer:
The graph is attached below.
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=-5x^4[/tex]
Since the leading term of the polynomial (the term in a polynomial that contains the highest power of the variable) is -5x⁴, then the degree is 4, i.e. even, and the leading coefficient is -5, i.e. negative.
This means that f(x) → −∞ as x → −∞ and f(x)→−∞ as x→∞.

What is the equation of the line of best fit that Mel drew?
Answer: the answer is y = 2/3x + 6
Step-by-step explanation: answer
The correct answer for the best line of fit is y = 2/3x + 6
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
In the scatter point it shows that the starting y-intercept is 6 and two of the options have a y-intercept of 15.
We have a picture of the line of fit if it has a slope of 1/3.
The 2/3 is the slope and 6 is the y intercept.
We know that Line of best of fit of the line shown in the scatter plot can be found by finding the slope (m) and the y-intercept (b) of the line then substituting each value into y = mx + b.
So, the correct answer is y = 2/3x + 6
