Answer:
41/25
Step-by-step explanation:
So (-1)¹⁰ equals 1 because any number multiplied by a positive exponent is positive. Next, you do (-22)⁰ which equals 1. Anything to the zeroth power equals one. Now you add 1 and 1 which equals 2. Then you do -(3/5)² which equals -9/25 (You do 3 * 3 which equals 9 and 5 * 5 which equals 25. You then add the negative sign outside the parenthesis to get -9/25). Then you multiply 2 by 25 so both numbers have a common denominator of 25. That equals 50/25 ( 50/25 is 2). You subtract 50/25 by 9/25. That equals 41/25.
Answer:
[tex]\frac{41}{25}[/tex]
Step-by-step explanation:
[tex](-1)^{10} + ( -22)^{0} - (\frac{3}{5})[/tex]
[tex]1 + (-22)^{0} - (\frac{3}{5})^{2}[/tex]
[tex]1 +1 - (\frac{3}{5} )^{2}[/tex]
[tex]1 + 1- \frac{9}{25}[/tex]
add the numbers
[tex]2 -\frac{9}{25}[/tex]
Calculate the difference
[tex]\frac{41}{25}[/tex] ← Final answer! ~ Hope this helps~

5 people are in a line to withdraw money from the local Bank. All 5 withdrawal the same amount. The total withdrawn was $845. How much money did each withdraw? Set up an equation to find out how much money each person withdrew and then solve it.
845 / 5 = 169
Each person withdrew 169$ from their accounts.
Shahida has seen an eagle landing at the top of the tree in her backyard. She places a camera on a tripod a distance of 12 feet from the
trunk of the tree. She angles the camera to the top of the tree so she can get a picture of the eagle. The height of the tree is 31 feet. The
height of the tripod is 4 feet.
The angle of elevation from the tripod to the top of the tree is about 66 degrees
What is trigonometric ratio?Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let Ф represent the angle of elevation. Since the tripod is at a height of 4 feet, hence:
tanФ = (31 - 4) / 12
Ф = 66 degrees
The angle of elevation from the tripod to the top of the tree is about 66 degrees

What is the slope of the line that passes through the points (1, 1) and (9, 7)?    
Answer:
slope =1
Step-by-step explanation:
(1, 1)=(x1,y1)
(9, 7)=(X2, y2)
now,
slope=(y2-y1)/(x2-x1)
=(7-1)/(9-1)
=8/8
=1

A culture started with 6000 becteria. after 4 hours it grew to 6600 becteria. Predict how many bacteria will be present after 10 hours. Round your answer to the nearest whole number. p=ae^kt
Answer:
7614
Step-by-step explanation:
The exponential growth of the bacteria culture can be modeled by the equation ...
p = a·b^(t/c)
where 'a' is the initial population, 'b' is the growth factor, and 'c' is the period over which that growth factor applies.
__
modelIn the given scenario, we have ...
a = 6000 bacteriab = 6600/6000 = 1.1 . . . . growth factorc = 4 hoursSo, our model is ...
p = 6000·1.1^(t/4)
__
applicationAfter 10 hours, the population is predicted to be ...
p = 6000·1.1^(10/4) ≈ 7614
We predict 7614 bacteria will be present after 10 hours.
__
Additional comment
If we compare the form we used to the one suggested in the proglem statement, we see
p = 6000·1.1^(t/4)p = 6000·e^(kt)For the bases of the exponential term to be the same, we must have ...
1.1^(t/4) = e^(kt)
(1.1^(1/4))^t = (e^k)^t . . . . . factor t from the exponent
1.1^(1/4) = e^k . . . . . . . match the bases
k = ln(1.1)/4 . . . . . take natural logs
k ≈ 0.0238275
and the equation becomes ...
p = 6000·e^(0.0238275t)
__
In terms of 'a', 'b', and 'c' used above, we find ...
k = ln(b)/c
