Write the equation of a line passing through (-4.3) and perpendicular to -6x + 4y =-12.
Answer:
y=-2/3*x+1/3
Step-by-step explanation:
-6x+4y=-12
put into y=mx+b line equation
4y=6x-12
y=(6/4)x-(12/4)
y=(3/2)x-4
slope is 3/2
to find perpendiular line slope take the negative inverse.
-(2/3) = slope of perpendicular line
use line equation and solve for y-intercept (b)
3=(-2/3)*(-4)+b
3=8/3+b
b= 9/3-8/3 = 1/3 : 3 = 9/3 to allow for subrtaction of fractions.
If f(x) = 3x + 4, what is the value of f(-4)?
Answer:
-8
Step-by-step explanation:
f(x) = 3x + 4
substitute -4 in place of x
f(-4) = 3*-4 + 4
f(-4) = -12 + 4
f(-4) = -8

a) what is the difference in temperatures between 7 am to 5 pm
b) which part of the day was the temperature rising the fastest a, b, c, d, or e?
Answers:
a) The difference in temperature is 25 degrees Fahrenheit. b) The temperature was rising fastest during interval 'a'=========================================================
Explanations:
a) We subtract the y coordinates of the left and right endpoints. We get 65-40 = 25b) The fastest rising temperature will visually correspond to the steepest part of the curve. That would be region 'a'. After this interval, region b is still increasing, but not as much as the previous interval (since it's not as steep here). Then it gets less steep for region c, and d sort of flattens out as well. So during the morning hours it appears the temperature is going up the fastest.PLEASE HELP WITH THIS QUESTION

amelia is going to invest in an account paying on interest rate of 6.5% compounded daily? help me plz someone
Answer:
$9,763
Step-by-step explanation:
Using the compund interest formula;
A = P(1+r)^t
A is the amount = $10,200
rate r = 6.5%= 0.065
time t = years
n = 1/365 ((daily compounding)
Substitute into the formula and get Pincipal P
10,200 = P(1+0.065(365))^5/365
10200 = P(1+23.725)^0.01369
10200 = P(24.725)^0.01369
10200 = P(1.0448)
P = 10200/1.0448
P = 9,762.6
Hence the amount invested is $9,763 to nearest dollars

Answer:x
=4
permiter=6
area=24
Step-by-step explanation:
Answer:
x = 8, area = 364 km^2, perimeter = 80 km
Step-by-step explanation:
to start, we have to recognize that opposite sides of a rectangle are congruent.
therefore ➪
2x + 10 = 4x - 6
2x + 16 = 4x
16 = 2x
x = 8
now just plug that in and you'll find ➪
length = 26km
width = 14km
area = l * w
area = 26 * 14
area = 364 km^2
perimeter = 2(l + w)
perimeter = 2(14+26)
perimeter = 80 km

30°
• He uses his protractor to draw a angle on one end of the line
segment.
ANSWER BOTH QUESTIONS ILL GIVE BRANLIEST AND LOTS OF POINTS .
Noah could draw a triangle with side lengths 4 cm, 6 cm, and approximately 10.39 cm, with angles of 30°, 30°, and 120°.
How to solveYes, there is a different triangle Noah could draw. Since Noah has only drawn one side and one angle, he can create two different triangles using the Angle-Side-Side (A S. S) ambiguity
To find the other possible triangle, we need to calculate the angle opposite the 6 cm side. In this case, the given angle is 30°. Using the sine rule, we can find the sine of the opposite angle (let's call it θ):
sin(θ) / 6 = sin(30°) / 4
sin(θ) = (6 * sin(30°)) / 4
sin(θ) ≈ 0.5
θ ≈ 30°
Since the sum of angles in a triangle is 180°, the other angle in the triangle is:
180° - 30° - 30° = 120°
Now, we can use the sine rule again to find the length of the side opposite this new angle:
x / sin(120°) = 6 / sin(30°)
x ≈ 6 * sin(120°) / sin(30°)
x ≈ 10.39 cm
Therefore, Noah could draw a triangle with side lengths 4 cm, 6 cm, and approximately 10.39 cm, with angles of 30°, 30°, and 120°.

Step-by-step explanation:
Two researchers are studying the decline of orangutan populations. In one study, a population of 784 orangutans is expected to decrease at a rate of 25 orangutans per year. In a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year. After how many years will the two populations be the same?
The two populations will be the same after
years.
Answer:
3 years
Step-by-step explanation:
Let y = number of orangutans, and let x = number of years.
For each study, the population, y, after x years is:
First study:
y = 784 - 25x
Second study:
y = 817 - 36x
We set the populations equal and solve for x, the number of years.
784 - 25x = 817 - 36x
Add 36x to both sides. Subtract 784 from both sides.
11x = 33
Divide both sides by 11.
x = 3
Answer: 3 years

Let h(x) = x*2 + kw - 8. If h(-1) = -5, what is the value of h(4)?
Help
Answer:
h(4) = 0
Step-by-step explanation:
Hoping its ' kx '
[tex]h(x) = x^2 + kx -8 \\\\h(-1) = (-1)^2 + k(-1) - 8\\\\-5 = 1 - k -8\\\\-5 = -k -7\\\\-5 + 7 = -k\\\\2 = -k\\-2 = k[/tex]
Now we have k = -2. We will find h(4).
[tex]h(4) = (4)^2 + (-2)(4) - 8 = 16 -8 - 8 = 0[/tex]
Answer:
h(4) = 0
Step-by-step explanation:
GIVEN :-
A quadratic function h(x) = x² + kx - 8h(-1) = -5TO FIND :-
Value of h(4)SOLUTION :-
To find the value of h(4) , you need to find 'k' first by using the given facts.
[tex]h(-1) = (-1)^2 + k(-1) - 8 = -5[/tex]
[tex]=> 1 - k - 8 = -5[/tex]
[tex]=> -k - 7 = -5[/tex]
Add both the sides by 7.[tex]=> -k - 7 + 7 = -5 + 7[/tex]
[tex]=> -k = 2[/tex]
Multiply both the sides by -1.[tex]=> -k(-1) = 2(-1)[/tex]
[tex]=> k = -2[/tex]
Putting the value of k,
[tex]h(4) = (4)^2 + (-2)(4) - 8[/tex]
[tex]= 16 - 8 - 8[/tex]
[tex]= 16 - 16[/tex]
[tex]= 0[/tex]
