Daniela and Jack are hiking a steady incline. They use their GPS device to determine their elevation every 15 minutes. At 15 minutes and 30 minutes they were at elevations of 10,300 and 10,900 feet, respectively. Write an equation expressing their elevation in relation to time.
Answer:
[tex]h=40t+9700[/tex]
where the elevation, h, is in feet and time, t, is in minutes.
Step-by-step explanation:
At the time, [tex]t_1=15[/tex] min, the elevation, [tex]h_1= 10,300[/tex] feet and
at the time [tex]t_2= 30[/tex] min, the elevation, [tex]h_2=10,900[/tex] feet.
As they are hiking a steady incline, so the change in the elevation with respect to time will be constant.
So, there will be a linear relationship between the elevation and the time.
Let [tex]h[/tex] be the elevation at any time instant [tex]t[/tex], so the linear relation among these quantities is
[tex]h=mt+C_0\;\cdots(i)[/tex]
where [tex]m[/tex] is the rate of change of elevation with respect to time and [tex]C_0[/tex] is constant.
The change in the elevation, [tex]\Delta h=h_2-h_1= 10,900-10,300=600[/tex] feet.
and the change in time, [tex]\Delta t=t_2-1_1=30-15=15[/tex] min.
So, change in the elevation in unit time,
[tex]m=\frac{\Delat h}{\Delta t}=\frac{600}{15}=40[/tex] feet/min.
Now, from equation (i)
[tex]h=40t+C_0[/tex]
As the elevation, [tex]h=h_1[/tex] at time [tex]t=t_1[/tex], so
[tex]10,300=40\times15+C_0[/tex]
[tex]\Rightarrow C_0=9700[/tex]
Hence, the required equation is
[tex]h=40t+9700[/tex]
where the elevation, [tex]h[/tex], is in feet and time, [tex]t[/tex], is in minutes.

q log a -3 log b
Condense logarithm
Answer:
Step-by-step explanation:
q log a is equivalent to log a^q. Note: This assumes that the base of your logarithmic system is 10.
-3 log b is equivalent to log b^(-3)
and so q log a -3 log b in condensed logarithm form is
log {a^q*b^(-3)}
a^q
or log -----------------
b^3

What is the equation of a line with a
slope of -2 and crosses the vertical axis
at the point (0, 5)?
Answer:
y=-2x+5
Step-by-step explanation:
the slope is m and the y-intercept is b in the form y=mx+b, and -2 is the slope and 5 is the y-intercept in this equation, so y=-2x+5
Answer:
y=-2x+5
Step-by-step explanation:
y=mx+b
m is the slope which is -2
b is the y intercept which is given in the problem, 5

Answer:
4th choice (if we guessed the blurry letters properly)
Step-by-step explanation:
The reflection maps ...
(x, y) ⇒ (x -y)
Then the rotation maps ...
(x, -y) ⇒ (y, x)
That is, R(-1, 4) becomes R'(4, -1), apparently matching point S, the only point at (4, -1). We can't read the letters, but we know that you only need to know where R ends up in order to select the correct answer.

factorise
a) 4p²-81
b) x²-13x+36
Answer:
A = (2p + 9) (2p - 9)
B = (x - 9) (x - 4)
Step-by-step explanation:
For A : Rewrite 4p^2 as (2p)^2.
(2p)^2−81
Rewrite 81 as 9^2.
(2p)^2−9^2
Since both terms are perfect squares, factor using the difference of squares formula, a^2 − b^2 = ( a + b ) ( a − b ) where a = 2p and b = 9 .
(2p + 9) (2p − 9)
For B : Consider the form x^2 + bx + c . Find a pair of integers whose product is c and whose sum is b . In this case, whose product is 36 and whose sum is − 13 .
-9, -4
(x - 9) (x - 4)
I hope this helps.

HELP What is an equation for the parallel to y= 3x-1 that passes through (-9,-2)
Answer:
The line parallel to this equation would be y=3x+25
Step-by-step explanation:
A parallel line has the same slope but a different y-intercept (so just ignore the "-1" in the equation ) Our goal is to find the y-intercept ("b")
We will start with
y=3x+b, plug in (-9,-2) for the x and y
-2=3(-9)+b
-2=-27+b, add 27 to both sides
-2+27=-27+27+b (the 27's on the right side cancel side)
b=25
our new equation is y=3x+25
