Answer:
D
Step-by-step explanation:
A^2+B^2=C^2
For A, 15^2(225)+20^2(200)=625, and 25^2=625
For B, 30^2(900)+40^2(1,600)=2,500, and 50^2=2,500
For C, 33^2(1,089)+44^2(1,936)=3,025, and 55^=3,025
But for D, 5^2(25)+12^2(144)=169, and 14^2=196, and 169 and 196 are not equal.

10.3% of 853.93km rounded to 2 dp
Answer:
87.95479
Step-by-step explanation:
10.3% of 853.93 km
Expand 10.3÷100 by multiplying both numerator and denominator by 10.
[tex] \small \sf \frac{10.3 \times 10}{100 \times 10} = 853.93 \\ [/tex]
[tex] \small \sf \frac{103}{1000} = 853.93 \\ [/tex]
convert decimal number 853.93 to fraction 85394÷100
[tex]\small \sf \frac{103}{1000} = \frac{85393}{100} \\[/tex]
Multiplying 103÷1000 and 85393÷100 by numerator times numerator and denominator times denominator.
[tex]\small \sf \frac{103 \times 8539 3}{1000 \times 100} \\[/tex]
Do the multiplication in the fraction
[tex]\small \sf \frac{8795479}{100000} \\ [/tex]
Divide we get
87.95479
Another way to solve it
10.3% 853.93
we know that ; % = whole no. ÷ 100
then,
10.3 ÷ 100 × 853.93
Divide the numbers
0.103 × 853.93
multiply the numbers
87.95479

Answer:
C. y = -2/3 x + 4
Step-by-step explanation:
y = mx + b
From the graph we see that b = 4, and m = 2/3.
y = -2/3 x + 4

Answer:
[tex]b=\frac{1}{6}[/tex]
Step-by-step explanation:
In [tex]f(x)=a\cos(b(x-c))+d[/tex], [tex]b[/tex] represents a constant related to the period of the function. Here's how it's related:
[tex]b=\frac{2\pi}{T}[/tex], where [tex]T[/tex] is the period of the function.
We're given [tex]T=12\pi[/tex], so solving for [tex]b[/tex]:
[tex]b=\frac{2\pi}{12\pi}=\boxed{\frac{1}{6}}[/tex]
What is the explicit formula for this arithmetic sequence?
-12,-17, -22, -27, ...
Answer:
Step-by-step explanation:
An explicit arithmetic formula in standard form is
[tex]A_n=a_1+d(n-1)[/tex] where n is the position of a number in thesequence, a1 is the first number in the given sequence, and d is the common difference. The common diff here is -5 since we have to subtract 5 from each term to get to the next one in the sequence. The first number is -12. So
a1 = -12
d = -5 and the explicit formula is
[tex]A_n=-12-5(n-1)[/tex] and you could simplify it a bit to
[tex]A_n=-12-5n+5[/tex] and finally to
[tex]A_n=-5n-7[/tex] which is a linear representation. Arithmetic sequences can all be simplified down to represent lines.

Which of the following is the equation of the line in slope-intercept form that has a slope of -2 and
passes through the coordinate (4, 1)?
A) y = –2x - 7
B) y -1 = -2(x - 4)
C) y = -2x + 9
D) y = -2x
Answer:
c). y = -2x + 9
Step-by-step explanation:
y = -2x + b
1 = -2(4) + b
1 = -8 + b
9 = b
Which linear equation best fits the data ?
Answer:
[tex]{ \tt{slope = \frac{2 - 1.5}{40 - 60} }} \\ = - 0.025 \\ \\ { \tt{y = mx + c}} \\ 2 = ( - 0.025 \times 40) + c \\ c = 3 \\ { \bf{ y = - 0.025x + 3}}[/tex]

Please help me with this question??m
Answer:
75
Step-by-step explanation:
f(1) = 7
f(n) = 3f(n-1) + 3
So what you are trying to do here is find the recursive value (that's what it is called) for f(n). Computers love this sort of thing, but we humans have to do it slowly and carefully.
So let's try f(2)
That means that f(2) = 3*f(n-1) + 3
but if f(2) is used it means that you have to know f(2-1) which is just f(1) and we know that.
so f(2) = 3*f(1)+3
f(2) = 3*7 + 3
f(2) = 21 + 3
f(2) = 24
Now do it again. We now know F(2), so we should be able to find f(3)
f(3) = 3*f(3 - 1) + 3
f(3) = 3*f(2) + 3 We know that f(2) = 24
f(3) = 3* 24 + 3
f(3) = 72 + 3
f(3) = 75

Answer:
1. $40
2. 10 computers
3. 300 miles
Step-by-step explanation:
1. Time between 12:00 and 2:00 is 2 hours, the difference in the money is $10, so the money earned per hour is $5. 5:00 is 3 hours from 2:00, so 25+5*3 is 40, or $40.
2. Time between 1:00 and 3:00 is 2 hours, and the difference in the numbers of computers fixed is 2, so the number of computers fixed per hour is 1. 6:00 is 3 hours from 3:00, so 7+3*1 is 10, or 10 computers.
3. Time between 6:00 and 9:00 is 3 hours and the difference in the distance is 150 miles, so the miles traveled per hour is 50. 12:00 is 3 hours from 9:00, so 150+50*3 is 300, or 300 miles.
The table below shows the typical hours worked by employees at a company. A salaried employee makes $50,000 per year. Hourly employees get paid $20 per hour, but get $30 per hour for each hour over 40 hours.

A landscape architect built a square playground. The outside edges of the playground measure 3x meters. The playground has an area of 8100 m^2. How much fencing is needed to fully enclose the playground?
Answer:
360 meters
Step-by-step explanation:
[tex]\sqrt{8100}[/tex] = 90
one edge = 90 meters
90 x 4 = 360
360 meters
A 60-foot zip line from a tree to the ground forms a 45 degree angle of elevation from the ground. How high above the ground is the top of the zip line? Round your answer to the nearest tenth of a foot.
Answer:
42.4 foot
Step-by-step explanation:
Please check the attached image for a diagram explaining the question
We would use sine to determine the required side
Sin 45 = opposite / hypotenuse
0.7071 = opposite / 60
60 x 0.7071 = 42.4 foot
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
