Write an exponential function that passes through the points (0, 3) and (-1, 6)
Answers
when x=0, y=3, 3=ab^0, so you can figure out that a=3
when x=-1, y=6, 6=3b^(-1), b^(-1)=2, b=1/2
so the equation is y=3(1/2)^x
Write the equation of the circle with center (0, 0) and (5, 2) a point on the circle.
Answers
the equation of the circle with center (0, 0) is ---------> x²+y²=r²
Step 1
find the radius
the radius is simply the distance from the center to the point (5,2)
d=√[(5²+2²)]-------> d=√29
r=√29
the equation of the circle is
x²+y²=29
the answer is x²+y²=29
r²=(x-h)²+(y-k)²
2. The center of this circle is (0,0), then:
h=0
k=0
3. When you substitute the values of h and k into the equation, you have:
r²=(x-h)²+(y-k)²
r²=(x-0)²+(y-0)²
r²=x²+y²
3. Now, you must find the radius "r".
4. You know that the point is (5,2), so:
r²=x²+y²
5. Finally:
√29=x²+y²
Sketch the following to help answer the question. Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P. Side QR = 5 m and diagonal QS = 6 m. Find the length of segment RP.
3 m
4 m
5 m
6 m
Answers
Since a kite is symmetric about one of its diagonals, then the other diagonal bisects that one. Additionally, the diagonals are perpendicular to each other. This forms two right triangles inside of the kite.
The bottom leg of the right triangle will be 3 (half of the diagonal) and the hypotenuse will be 5. We will use the Pythagorean theorem to answer this:
3²+b²=5²
9+b²=25
Subtract 9 from both sides:
9+b²-9=25-9
b²=16
Take the square root of both sides:
√(b²) = √16
b=4
Answer:
Given: Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P. Side QR = 5m and diagonal QS = 6m.
Since, diagonals of kite bisect each other, thus QP=6m
Now, in ΔPQR, we have
(QR)²= (RP)²+(QP)²
(5)²= (3)²+(RP) ²
25=9+(RP)²
25-9= (RP)²16= (RP)²
RP= 4m
Therefore, the length of segment RP is 4m.

c. How many years will it take for the population to become 1150.
Show all work!
Answers
Answer(a):
Exponential growth formula is given by
[tex]A=P(1+r)^t[/tex]
Where preset population = P= 775
Rate of increase = r = 51% = 0.51
t= number of years
A= Future value.
Plug these values into above formula:
[tex]A=775(1+0.51)^t[/tex]
[tex]A=775(1.51)^t[/tex]
Hence required exponential function is [tex]A=775(1.51)^t[/tex]
Answer(b):
plug t=10 years
[tex]A=775(1.51)^t=775(1.51)^{10}=775(61.6267795034)=47760.7541151[/tex]
which is approx 47761.
Answer(c):
Plug A=1150
[tex]1150=775(1.51)^t[/tex]
[tex]\frac{1150}{775}=(1.51)^t[/tex]
[tex]\ln(\frac{1150}{775})=t*\ln(1.51)[/tex]
[tex]0.394654192004=t*0.412109650827[/tex]

What does the 80 inches represent in an 80" TV
Answers
The 80 inches on an 80" TV refers to the diagonal measurement of the screen, which determines the size of the TV. This measurement is essential for potential buyers to know to match the TV to their space and optimal viewing distance. Other factors like screen resolution and whether to choose plasma or LCD also influence the viewing experience and cost.
When we refer to an 80" TV, the 80 inches represents the diagonal measurement of the screen. This measurement is taken from one corner to the opposite corner of the screen, not horizontally or vertically, which is the standard for sizing televisions and monitors. The importance of considering screen size arises from the need to match the viewer's space and viewing distance to optimize the viewing experience. With larger screens, such as an 80-inch TV, viewers can enjoy a more immersive viewing experience, especially when watching sports, movies, or DVDs. However, depending on the resolution, like 1080p for full HD or 768p for a lower resolution, the quality of the image may affect the perceived difference in quality, especially on smaller screens in which it might not be distinguishable to the nak.ed eye.

find the difference 6x^2-14x+4/x(x-2) - 6x-1/x+1
Answers
Final answer:
To find the difference between two expressions in the given question, you need to simplify each expression first and then subtract them. The steps involve simplifying each expression separately and then performing the subtraction.
Explanation:
To find the difference 6x² - 14x + 4 / x(x - 2) - 6x - 1 / x + 1, you need to first simplify each expression and then subtract them from each other.
Step 1: Simplify each expression separately.
6x² - 14x + 4 / x(x - 2) = (3x - 2)(2x - 1) / x(x - 2) = 3(2x - 1) / x
- 6x - 1 / x + 1 = -6 - 1 / x + 1 = -7 / (x + 1)
Step 2: Subtract the two simplified expressions: 3(2x - 1) / x - 7 / (x + 1).

I'll solve the first two systems.
1)
[tex] \left \{ {{5x+2y=21} \atop {-x-y=-9}} \right. [/tex]
Multiply the second equation in the system by 2 to be able to cancel out y-terms:
[tex]-x-y=-9[/tex]
[tex]2(-x-y=-9)[/tex]
[tex]-2x-2y=-18[/tex]
Now, add the equations together:
[tex] \left \ {{5x+2y=21} \atop {-2x-2y=-18}} \right. [/tex]
_____________
[tex]3x-0=3[/tex]
[tex]3x=3[/tex]
[tex]x=1[/tex]
Plug 1 for x into one of the original equations to find y:
[tex]5x+2y=21[/tex]
[tex]5(1)+2y=21[/tex]
[tex]5+2y = 21[/tex]
[tex]2y=16[/tex]
[tex]y =8[/tex]
Check work by plugging your values for x and y back into both original equations:
[tex] \left \ {{5x+2y=21} \atop {-x-y=-9}} \right. [/tex]
[tex] \left \ {{5(1)+2(8)=21} \atop {-(1)-(8)=-9}} \right. [/tex]
[tex] \left \ {{5+16=21} \atop {-1-8=-9}} \right. [/tex]
Both are true; x = 1 and y = 8.
2)
[tex] \left \ {{3x+2y=13} \atop {3x+4y=1}} \right. [/tex]
For this system, to be able to cancel out x-terms, you can multiply either equation by -1; I'll use the bottom equation:
[tex]-1(3x+4y=1)[/tex]
[tex]-3x-4y=-1[/tex]
Now add the equations together:
[tex] \left \ {{3x+2y=-13} \atop {-3x-4y=-1}} \right. [/tex]
_____________
[tex]0-2y=-14[/tex]
[tex]-2y = -14[/tex]
[tex]y=7[/tex]
Plug 7 for y into either of the original equation to solve for x:
[tex]3x+2(7)=-13[/tex]
[tex]3x+14=-13[/tex]
[tex]3x = -27[/tex]
[tex]x=-9[/tex]
Plug -9 for x and 7 for y into each original equation to check work:
[tex] \left \ {{3(-9)+2(7)=-13} \atop {3(-9)+4(7)=1}} \right. [/tex]
[tex] \left \ {{-27+14=-13} \atop {-27+28=1}} \right. [/tex]
Both are correct; x = -9 and y = 7.

Then, the dot ran from −34 to −66. What distance did it cover? If this run took the dot 5 minutes, what was its average speed?
Answers
Final answer:
The dot covered a distance of 32 units when it ran from -34 to -66. Assuming the distance is measured in meters, and the dot took 5 minutes (300 seconds) to cover this distance, the average speed would be 0.1067 m/s.
Explanation:
To determine the distance the dot covered when it ran from -34 to -66, we need to calculate the absolute value of the difference between the two points. The formula for distance in this case is |final position - initial position|, so the distance covered = |-66 - (-34)| = |-66 + 34| = | -32 | = 32 units.
Now, to determine the average speed of the dot, we divide the total distance traveled by the time it took to cover that distance. Given that it took the dot 5 minutes to cover the distance, we convert minutes to seconds because speed is typically measured in meters per second (m/s) in physics. There are 60 seconds in a minute, so 5 minutes is 300 seconds. Therefore, the average speed is distance/time = 32 units / 300 seconds.
The exact units of measurement for distance have not been specified in the question, but assuming the distance is in meters (m), the average speed would be calculated as 32 m / 300 s = 0.1067 m/s.

PART A: All but two of the pyramids built by the ancient Egyptians have faces inclined at 52 degree angles. Suppose an archaeologist discovers the ruins of a pyramid.

Round your answer to the nearest meter.
25 m
32 m
52 m
105 m,
Answers
The height forms a right triangle with the slant height of the pyramid and half of the length of the square base. Half of the length of the square base would be 41m. The angle is 52°. The sides we have are the height, which is opposite the angle, and half of the base, which is adjacent to the angle. The ratio opposite/adjacent is used for the tangent. Our equation would be:
tan 52=h/41
We multiply both sides by 41:
41*tan 52 = (h/41)*41
41*tan 52 = h
Evaluating this we get 52m.
In the problem, we were asked to compute for the height of the pyramid. Given are the base of the pyramid which is 82 m and the angle of 52°.
If given an illustration, the height is opposite to the angle and the adjacent side is given by half the base.
Based on the mnemonics of trigonometry (SOH CAH TOA), the function to be used is tangent.
The computation is as follows:
Let h = height of pyramid (m)
tan52 = h/41
h = 41tan52
h ≈ 52.5 m
Hence, the height of the pyramid is approximately 52.5.
However, the closest answer based on the choices you provided is 52 m.
