1/2 = q + 2/3
and
p - 3 1/6 = -18.73
please help, im giving 20 points
Answers
Answer:
see below
Step-by-step explanation:
1/2 = q + 2/3
Subtract 2/3 from each side
1/2 -2/3 = q+2/3-2/3
Getting a common denominator of 6
3/6 - 4/6 = q
-1/6 =q
p - 3 1/6 = -18.73
Add 3 1/6 to each side
p - 3 1/6 + 3 1/6 = -18.73 + 3 1/6
p = -18 73/100 + 19/6
Get a common denominator
p =- 5619/300 + 950/300
= -4669/300
=-15 169/300

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.
Answers
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.

Answers
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)}

b) x²-13x+36
Answers
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 .

HELP What is an equation for the parallel to y= 3x-1 that passes through (-9,-2)
Answers
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

Given the parent function f(x) on the left below, which graph could represent g(x) = -f(x) -2
Answers
Answer:
A
Step-by-step explanation:
To do this, you look at each point. What -f(x) means is that you flip the function over the x axis. In this case, c doesn't work. Then, you have to look at the -2 term. That means that the entire function, all the points, are shifted 2 units down. The image isn't very clear for me but I am pretty sure it is A.
