Answer (assuming it can be in point-slope form):
[tex]y-4 = 3(x+2)[/tex]
Step-by-step explanation:
Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex], to write the equation of the line in point-slope form. Substitute x and y values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula.
Since [tex]m[/tex] represents the slope, substitute 3 for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, take the x and y values of point P and substitute them into the equation as well. Substitute -2 for [tex]x_1[/tex] and 4 for [tex]y_1[/tex]. This gives the following answer:
[tex]y-4 = 3(x+2)[/tex]

find the area of a regular hexagon with side length of 10 and apothem of 8.7 meters
HELP PLZZZ
Answer:
43.5 meters
Step-by-step explanation:
Area of regular hexagon =
[tex] \frac{1}{2} \times ap[/tex]
in the problem you have a = 10 meters
and p = apothem = 8.7 meters
so if you apply the formula
you will have
area =( 1/2) × 10 × 8.7
area = 43.5 meters

In a lab experiment, 80 bacteria are placed in a petri dish. The conditions are such
that the number of bacteria is able to double every 19 hours. How many bacteria
would there be after 17 hours, to the nearest whole number?
Answer:
After 17 hours there will be about 143 bacteria.
Step-by-step explanation:
Given that in a lab experiment, 80 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 19 hours, to determine how many bacteria would there be after 17 hours, to the nearest whole number, the following calculation must be performed:
80 x ((2/19) x 17) = X
80 x (0.1052 x 17) = X
80 x 1.7894 = X
143.15 = X
Thus, after 17 hours there will be about 143 bacteria.

how do you solve 5% of 58
Answer:
2.9
Step-by-step explanation:
5% of 58
58 × 5 ÷ 100 = 2.9
Step-by-step explanation:
Convert 5% to a fraction first.
[tex]5\% = \frac{5}{100} \\ = \frac{1}{20} [/tex]
5% of 58
=
[tex] \frac{1}{20} \times 58 \\ = \frac{58}{20} \\ = \frac{29}{10} \\ = 2.9[/tex]
The height of a batted baseball is modeled by the equation h(t) = -16t²+64t+6, where t is measured in seconds and h is measured in feet.
a.) At what time in seconds does the ball attain its maximum height?
b.) What is the maximum height attained by the ball? (Give your answer in feet.)
Answer:
[tex] \frac{dh}{dt} = - 32t + 64 = 0 \\a) \: t = \frac{ - 64}{ - 32} = 2 \\ \\ b = - 16 \times 4 + 64 \times 2 + 6 = - 64 + 2 \times 64 + 6 = 64 + 6 = 70[/tex]
Answer:
a) t = 2 seconds
b) 70 feet
Step-by-step explanation:
First of all, we are going to take the derivative of the function (which is a displacement function) to make find its velocity function.
[tex]h(t) = -16t^{2} +64t+6[/tex]
To find the derivative of the equation, we must multiply the coefficient by the exponent and then minus one from the exponent for each term.
[tex]v(t)=(-16)(2)t^{2-1} +64(1)t^{1-1}+6(0)t^{0-1} \\v(t) = -32t +64[/tex]
Now we can substitute in v=0
This is because the ball is at the top of its parabola path, it is the turning point and the slope is 0. The velocity physically speaking would also be 0 at the very top of its path.
[tex]0=-32t+64[/tex]
Rearrange and we get:
[tex]32t = 64\\t=2[/tex]
Ball attains maximum height at 2 seconds.
To find the maximum height, we now just have to substitute back in the time into the original equation to find the height.
[tex]h(t) = -16t^{2} +64t+6[/tex]
[tex]h(2) = -16(2)^{2} +64(2)+6\\h(2)=-64+128+6\\h(2) = 70[/tex]
The maximum height attained is 70 feet.
Hope this helped!
A telephone call costs $0.15 for the first minute, plus $0.05 for each
additional minute. The total cost of the call was $1.30. This equation
can be used to find m, the length in minutes of the telephone call.
0.15 + 0.05(m - 1) = 1.30

A quantity with an initial value of 5700 decays exponentially
at a rate of 7.5% every 2 days. What is the value of the
quantity after 234 hours, to the nearest hundredth?
Answer:
36.5625
Step-by-step explanation:
so, if it decays at a rate of 7.5% every 2 days, and we have 234 hours, we do the following, 234/24, since there are 24 hours in a day, that gives us 9.75, "7.5% every 2 days" so we do this, 9.75/2 = 4.875
4.875 * 7.5 = 36.5625
i migt be wrong, but i'm pretty sure this is the answer, i'm not saying this is the answer like some people do, please let me know if i'm wrong.
Answer:
3897.77
Step-by-step explanation:
Decays 7.5%→r=0.075 (divide by 100)
Decays every 2 days: exponent of t/2
(where t is in days)
function- f(t)=5700(1−0.075) ^t/2
234 hours→234/24→9.75 days
Plug in t=9.75
f(9.75)=5700(1−0.075) ^9.75/2
3897.76635734
≈3897.77
