Answer:

f(0) = 0

f(-2) = 0

f(5) = 15

f(-10) = 16

Step-by-step explanation:

Piecewise functions have multiple pieces of curves/lines where each piece corresponds to its definition over an interval.

Given piecewise function:

[tex]f(x)=\begin{cases} \begin{aligned}-2x-4 & \;\;\textsf {if }\;x < 0\\3x & \;\;\textsf {if }\;x\geq 0\\\end{aligned}\end{cases}[/tex]

Therefore, the function has two definitions:

When graphing piecewise functions:

First piece of the function

Substitute zero into the first function:

[tex]\implies f(0)=-2(0)-4=-4[/tex]

Place an open circle at point (0, -4).

To help graph the line, find another point on the line by inputting another value of x that is less than zero into the same function:

[tex]\implies f(-2)=-2(-2)-4=0[/tex]

Place point (-2, 0) and draw a straight line from the open circle at (0, -4) through (-2, 0).  Add an arrow at the other endpoint to show it continues indefinitely as x → -∞.

Second piece of the function

Substitute zero into the second function:

[tex]\implies f(0)=3(0)=0[/tex]

Place an closed circle at point (0, 0).

Again, to help graph the line, find another point on the line by inputting another value of x that is more than zero into the same function:

[tex]\implies f(2)=3(2)=6[/tex]

Place point (2, 6) and draw a straight line from the closed circle at (0, 0) through (2, 6).  Add an arrow at the other endpoint to show it continues indefinitely as x → ∞.

See attached for graph.

To find the given functions, decide which function to use based on the given value of x, then solve.

f(0) means to find the value of the function when x = 0.

Therefore, input x = 0 into the second function as x ≥ 0.

[tex]\implies f(0)=3(0)=0[/tex]

f(-2) means to find the value of the function when x = -2.

Therefore, input x = -2 into the first function as x < 0.

[tex]\implies f(-2)=-2(-2)-4=0[/tex]

f(5) means to find the value of the function when x = 5.

Therefore, input x = 5 into the second function as x ≥ 0.

[tex]\implies f(5)=3(5)=15[/tex]

f(-10) means to find the value of the function when x = -10.

Therefore, input x = -10 into the first function as x < 0.

[tex]\implies f(-10)=-2(-10)-4=16[/tex]

Philip's mistake is he did not add zero at ten's place.

When the multiplication is performed with two or more digits in the bottom number, zeroes are added as per the position. We see that in number 21, one is at one's place and 2 is at ten's place. Hence, when multiplying the digit 2 with the number 1659, we will add zero at one's place.

Performing the correct multiplication -

1659

× 21

1659

+33180

The result of multiplication will be the sum of numbers 1659 and 33180.

Result = 34,839

Therefore, the multiplication of the numbers will give result 34,839. Hence, the mistake is not keeping zero at one's place, while performing multiplication.

Domain: (-∞, ∞)

Range: (-∞, ∞)

Domain and range help us describe the values a graph covers.

Defining Domain and Range

Remember that the x-values are along the horizontal axis, and the y-values are on the vertical axis.

The function given to us extends infinitely to the left and right as shown by the arrows. Additionally, the graph extends up and down infinitely; thus the range is also infinite.

Interval Notation

Interval notation should be written as (minimum value, maximum value). If the minimum and maximum values are included within the range or domain, then the parentheses should be replaced with brackets. This looks like [included minimum, included maximum]. Since a function cannot actually include infinity, an infinity symbol should never have brackets.

Eventually, this linear function will reach every single x and y-value in existence. So, both axes have a minimum of -∞ and a maximum of ∞. Thus, both the domain and range are (-∞, ∞).

Hint for future problems: all linear functions will have a domain and range of (-∞, ∞).

The given triangle whose sides are 6cm, 10cm, and 12cm is an obtuse triangle and it can be determined by using Pythagorean theorem which is the correct option (C).

Pythagoras theorem states that a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

The given triangle whose sides are 6cm, 10cm, and 12cm

Now, applying Pythagorean's theorem:

⇒ 6² + 10² = 12²

⇒ 36 +100 = 144

⇒ 136 = 144

Here, it is clearly observed that 136 <  144 therefore, the triangle is obtuse.

Therefore, the given triangle whose sides are 6cm, 10cm, and 12cm is an obtuse triangle

Answer:

26

Step-by-step explanation:

[tex]FH=7+19=26[/tex]

Answer:

FH = 26

Step-by-step explanation:

The equation will be,

→ FH = FG + GH

Then the value of FH will be,

→ FH = 19 + 7

→ [ FH = 26 ]

Hence, the value of FH is 26.

Answer:

[tex]P_{rofit}=13x-50\\C_{ost}(70)=960\\P_{rofit}(70)=860\\C_{ost}(100)=1350\\P_{rofit}(100)=1250\\For\ a\ profit\ of\ \$1100\ one\ must\ sell\ 89\ stuffed\ animals.[/tex]

Step-by-step explanation:

I would suggest starting with 1 and working to 4, as it is set up for you like that.

I would start by writing down what you know, then what you need as follows:

[tex]Givens:\\ C_{ost}=13x+50;\\ R_{evenue}=36x;\\P_{rofit}=R_{evenue}-C_{ost};\\ x=N_{umber\ of\ animals}\\[/tex]

[tex]Find:\\1.\ Profit\ equation\\2a.\ C_{ost}\ to\ make\ 70\ animals\\2b.\ P_{rofit}\ from\ selling\ 70\ animals\\3a.\ C_{ost}\ to\ make\ 100\ animals\\3b.\ P_{rofit}\ from\ selling\ 100\ animals\\4.\ N_{umber}\ of\ animals\ needed\ to\ produce\ P_{rofit}\ of\ \$1100[/tex]

Now you can read it easier. Given that Profit is Revenue minus Cost, plug the equations for Cost and Revenue into the Profit equation as follows:

[tex]P_{rofit}=36x-(13x+50)\\NOTE:\ Do\ NOT\ forget\ to\ put\ the\ C_{ost}\ equation\ in\ parenthesis\ as\ you\ \\must\ subtract\ the\ entire\ C_{ost}.\\\\Distribute\ the\ negative:\ P_{rofit}=36x-13x-50\\Combine\ like\ terms:\ P_{rofit}=13x-50[/tex]

With the Profit equation, it is now easier to solve 2b, 3b, and 4.

[tex]C_{ost}\ for\ 70: C_{ost}=13(70)+50=(700+210)+50\\NOTE:\ I\ used\ the\ fact\ that\ 13*70=(10+3)*70=10*70+3*70\\C_{ost}=910+50=960\\This\ could\ also\ be\ written\ more\ clearly\ as\ C_{ost}(70)=960\\\\P_{rofit}(70) = 13(70)-50\\P_{rofit}(70)=(700+210)-50\\P_{rofit}(70)=910-50\\P_{rofit}(70)=860\\\\C_{ost}(100)=13(100)+50\\C_{ost}(100)=(1300)+50\\C_{ost}(100)=1350\\\\P_{rofit}(100)=13(100)-50\\P_{rofit}(100)=(1300)-50\\P_{rofit}(100)=1250\\[/tex]

Problem 4 will involve using the (now) known amount for profit, $1100 to find the unknown number of animals. This will involve a little bit more "algebra" compared to the prior questions.

[tex]P_{rofit}(x)=1100=13x-50\\1100=13x-50\\[/tex]

Because 13x - 50 is 1100, 13x will be 1100 + 50, just as

[tex]5*2+10 = 20\\5*2=20-10\\[/tex]

So, add 50 to both sides:

[tex]1100+50=13x-50+50\\1150=13x\\[/tex]

Because 13x is 1150, x will be 1150÷13, just as

[tex]5*2=10\\5=\frac{10}{2}[/tex]

So, divide 13 from both sides:

[tex]\frac{1150}{13}=\frac{13x}{13}\\\\\frac{1150}{13}=x[/tex]

Because 1150/13 is not an integer, use a calculator, or simplify the improper fraction to obtain...

x=88.5 (Approximately)

But, because you cannot sell half an animal, you would have to sell 89 in order to profit $1100, for bonus points, what is the actual profit accrued by selling 89 animals?

the algae that is present with the scientist to research upon covers a surface area of 2004 inches² in the rectangular prism.

The dimensions of the rectangular prism is given by:

Height = h = 18 inches

Width = w = 14 inches

Length = l = 30 inches

Now, we have to calculate the surface area of the tank excluding the top of the tank to find out how much algae has been present there for the scientist to test.

So, the formula for surface area will become:

A = 2(w l + h l + h w) - l w ( as the top has to be excluded)

Now substituting the values of l, w and h, we get that:

A = 2 [ (14) (30) + (18) (30) + (18) (14) ] - (30) (14) inches²

A = 2 [ 420 + 540 + 252 ] - 420 inches²

A = 2 [ 1212 ] - 420 inches²

A = 2424 - 420 inches²

A = 2004 inches²

Senior citizen tickets (s) = 9

Child tickets (c)              = 7

Total price of both tickets = $154

9s + 7c = 154   eq. (2)

Multiplying equation 2 with 2, we get

18s + 14c = 308    eq. (3)

Now, we will subtract eq. (1) from eq. (3)

18s + 14c = 308    eq. (3)
