Using the features, a piece-wise function is defined, and the graph is sketched at the end of this answer.
A piece-wise function is a function that has multiple definitions, depending on the value of the input.
He starts at 0 feet, and reaches a maximum elevation of 800 feet in 30 minutes, with a steady(linear) increase thus, for the first 30 minutes, the definition is:
[tex]h(t) = \frac{800}{30}t, 0 \leq t < 30[/tex]
For the next 5 minutes, he stops to rest, at the maximum elevation of 800 feet, thus, the definition is:
[tex]h(t) = 800, 30 \leq t < 35[/tex]
For the final 20 minutes, he descends 800 meters, at a linear rate, thus:
[tex]h(t) = 800 -\frac{800(t-35)}{20} = 800 - 40(t - 35), 35 \leq t \leq 55[/tex]
Using these definitions, the graph is sketched at the end of this answer.

Solve and graph the absolute value inequality: 12x +41 > 8.
Answer:
Answer is C
The inequality is x
<−6 or x>2
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
| 2x + 4 | > 8
Case I Case II
2x + 4 > 8 -(2x +4) > 8
-4 -4 -2x - 4 > 8
2x > 4 +4 +4
x > 4/2 -2x > 12
x > 2 -x > 12/2
-x > 6
x < - 6 Multiply by -1 will change the inequality sign.
x > 2 and x< - 6
x > 2 open circle at 2 and shade to the right.
x < -6 open circle at -6 and shade to the left
If the cost, C(x), for manufacturing x units of a certain product is given by C(x)=x2−19x+50 find the number of units manufactured at a cost of $8150
Answer:
Step-by-step explanation:
C(x) = ax2 + bx + c
C(x) = x2 -19x + 50
8150 = x2 -19x + 50
x2 -19x + 50 = 8150
x2 -19x-8100 = 0
this is a quadratic equation, solved as
x = −b ± √(b2 − 4ac) 2a ·
or
x = −(-19) ± √((-19)x(-19) − 4(1) x(-8100))/2 ·
x= 19± √((-19)x(-19) − 4(1) x(-8100))/2
x = 100

MARKING BRAINLEIST + 20 POINTS PLEASE HELP IS DUE TODAY
Answer: The slope is 1.5. The equation of the line is y=1.5x+3
Step-by-step explanation:
Slope is the "Rise" over the "Run" of a line. The rise is the change in y. The run is the cange in x. Take any two points. I picked (0,3) and (4,9) since they were clearly on whokle number lines. The rise is (9-3) or 6. The run is (4-0) or 4. Rise/Run = 6/4 or 1.5. The y intercept is at 3 (the value of y when x=0). The full line equation is thus y = 1.5x+3.
What is the slope of the line that passes through (-4, 5) and (2, -3)?
Answer:
[tex]m=\frac{-4}{3}[/tex]
[tex]y=\frac{-4}{3}x -\frac{1}{3}[/tex]
Step-by-step explanation:
Use the Slope formula...
[tex]\frac{-3-5}{2-(-4)}[/tex]
[tex]\frac{-8}{6} = \frac{-4}{3}\\\frac{-4}{3} = m[/tex]
Plug the slope into the Point-Slope formula...
[tex]y -(5) = \frac{-4}{3}(x-(-4)) \\y+5=\frac{-4}{3}x +\frac{-16}{3}\\y=\frac{-4}{3}x +\frac{-1}{3}[/tex]

Insert 5 geometric means between -4 and -62 500
9514 1404 393
Answer:
Either of ...
{-20, -100, -500, -2500, -12500}{20, -100, 500, -2500, 12500}Step-by-step explanation:
For some common ratio r, the first of the "geometric means" will be -4r, the next will be -4r^2, and so on. The 5th will be -4r^5, and finally, -62500 will be -4r^6.
Solving this last relation for r gives ...
-4r^6 = -62500
r^6 = 15625
Then r can be either of ...
r = ±15625^(1/6) = ±5
For r = 5, the means are ...
-4·5 = -20, and -100, -500, -2500, -12500
For r = -5, the means are ...
-4(-5) = 20, and -100, 500, -2500, 12500

What is the sum of the roots of the equation 2 x^2 + 5 x − 3 = 0?
a)-3.5
b)-2.5
C)-1.5
D)2.5
Answer:
B) -2.5
Step-by-step explanation:
2x^2 + 5x -3 = 0
(2x - 1)(x + 3) = 0
2x - 1 = 0; 2x = 1, so x = 1/2 = ROOT 1
x + 3 = 0, so x = -3 = ROOT 2
Now add the roots: -3 + 1/2 = - 2 1/2, so the answer is B.
can someone please help me with how to find the perimeter and area of this
Answer:
Perimeter = 68ft
Area = 289ft²
Step-by-step explanation:
The lines on each side mean that they are all the same length - this shape is a square.
To find the perimeter, do 17 + 17 + 17 + 17 or 17 × 4. This gives you 68ft.
To find the area, you multiply the length and width → 17 × 17 = 289ft²
Hope this helps!
