If two angles are complements, then they are both acute. Which is the hypothesis?
Answer:
the hypothesis is "two angles are complements"
Step-by-step explanation:
In the given statement, the hypothesis is "two angles are complements".. While the conclusion is that "they are both acute".
The hypothesis of the two angles being complements is what led to the conclusion that they are both acute since sum of 2 complementary angles is 90° and acute angle is any angle that measures less than 90°.
If f(x)=3^ x-4 what is f(- 1) ?
Answer:
1/243
Step-by-step explanation:
When you see this notation, it means plug in -1 for x in the function.
f(-1) = 3^((-1)-4)
f(-1) = 3^-5
f(-1) = 1/3^5
f(-1) = 1/243
Step-by-step explanation:
substitute (-1)
[tex] {3}^{x} - 4 \\ {3}^{ - 1} - 4 = \frac{1}{3} - 4 = - \frac{11}{3} = - 3.667[/tex]
Find the y-coordinate of the y-intercept of the polynomial function defined below. f(x)=2(3x+4)(x^2+2)
Answer:
Step-by-step explanation:
The best way to find out the answer to your question is to graph the cubic. As you can see, the y intercept is (0,16).
How was this obtained. notice that if x = 0 then
f(0) = 2(3*0+4)(0^2 + 2)
f(0) = 2(4)(2)
f(0) = 16 just as the graph tells us.

The equation k = 1.6d gives an approximate relationship between d miles and k kilometers. The distance between Boise, Idaho, and Reno, Nevada, is 430 miles. Express the distance in kilometers.
A.
431.6 km
B.
268.8 km
C.
688 km
Answer:
B
Step-by-step explanation:
Answer:
The answer is C. 688 km
Step-by-step explanation:
you do is multiply the miles x 1.6 and you will get k. so 430miles x 1.6 = 688k
and 665miles x 1.6 = 1064k
1 Mile is 1,6 Kilometers
430 Miles = 688 Kilometers (430 * 1,6)
665 Miles = 1064 Kilometers (665 * 1,6)
1. if you want your questions answered, don't whine -- just ask the question. for example, in this you haven't really asked anyone the question. They have to assume what you are trying to find out.
2. It is simple math if you understand the equation you gave:
You are solving for "k" which is kilometers;
You have been given the distance which is "d" in miles (430 miles and 665 miles)
The equation means: "k" equals 1.6 times the value of "d"
so the answers to your implied questions are:
k = 430 x 1.6 = 688 kilometers
k = 665 x 1.6 = 1064 kilometers
You might also asking your question in a more appropriate category. this is more of a math problem than a geography question (the names of the cities is irrelevant to the answer; the relevant part is the distance in miles).
The number of kilometers is ALWAYS greater than the corresponding miles. For example 1 mile = 1.6 km, so there is no way that when you convert miles to kilometers you will ever come up with a lower number of kilometers than the miles.
Miguel has triple David's money, while Lisbeth has ten dollars less than David. The sum of their money totals $95. How much money does David have?
Answer:
Miguel has $63
Lisbeth has $11
David has $21
Step-by-step explanation:
let Miguel share be M
let Lisbeth share be L
let David share be D
from the question, we know that
M=3D
L=D-10.
M+L+D=95
thus,
3D+(D-10)+D= 95
3D+D-10+D= 95
5D-10 = 95
5D= 95+10
5D= 105
D= 105/5
D= 21.
thus,
M = 3D = 3×21
= $63
L = D-10 = 21-10
= $11
(63+21+11)$ = $95

A park is in the shape of a rectangle 300 feet long 50 feet wide Amaya is standing at one corner of the park at point x he then walks in a straight line to the opposite corner at point y how far does he walk rounded to the nearest tenth
Answer:
[tex]304.1\ \text{feet}[/tex]
Step-by-step explanation:
The dimensions of the rectangle are 300 feet long 50 feet wide
The length between [tex]x[/tex] and [tex]y[/tex] will be the length of the diagonal of the rectangle.
Length of the diagonals can be found using the Pythagoras theorem
[tex]\sqrt{300^2+50^2}=304.138\approx 304.1\ \text{feet}[/tex]
The distance walked from [tex]x[/tex] to [tex]y[/tex] is [tex]304.1\ \text{feet}[/tex].
Robert purchased a 2010 model sedan for $16,000. The dealership offered
him a $99/month payment for 60 months, after which the unpaid balance is
due. If the interest rate is 6%, find the balloon payment due at the end of 60
months.
O
A. $17,513.12
O
B. $15,000
C. $18,153.21
O
D. $14,674.37
Answer:
The correct option is D. $14,674.37.
Step-by-step explanation:
This can be calculated using the ballon payment formula as follows:
P = (PV - (Ballon / (1 + r)^n)) * (r / (1 – (1 + r)^-n)) ...................... (1)
Where:
P = Monthly payment = $99
PV = present value of the loan or the purchase price of the 2010 model sedan = $16,000
Ballon = Ballon payment due at the end of 60 months = ?
r = monthly interest rate = 6% / 12 = 0.06 / 12 = 0.005
n = number of periods or months = 60
Substituting the values into equation (1) and solve for Ballon, we have:
$99 = ($16,000 - (Ballon / (1 + 0.005)^60)) * (0.005 / (1 -(1 + 0.005)^-60))
$99 = ($16,000 - (Ballon / 1.3488501525493)) * 0.0193328015294284
$99 / 0.0193328015294284 = ($16,000 - (Ballon / 1.3488501525493))
$5,120.83051436193 = $16,000 - (Ballon / 1.3488501525493)
Ballon / 1.3488501525493 = $16,000 - $5,120.83051436193
Ballon / 1.3488501525493 = $10,879.1694856381
Ballon = $10,879.1694856381 * 1.3488501525493
Ballon = $14,674.3694203126
Rounding to 2 decimal places, we have:
Ballon = $14,674.37
Therefore, the correct option is D. $14,674.37.

Jacob has 17 yards of fabric. He uses 1 third of it to make a cape. How many yards of fabric does Jacob use for the cape? Solve on paper. Write your answer as a mixed number. 17 yards ? Jacob uses yards of fabric for the cape.
Answer:
Joseph used [tex]5\frac{2}{3}\ yards\ of\ cape[/tex]
Step-by-step explanation:
Total fabric available = 17 yards
fraction used = one-third = 1/3
Let us convert this fraction to actual number
He used one-third of total
= [tex]\frac{1}{3}\ of\ 17\\=\frac{1}{3} \times \frac{17}{1} = \frac{17}{3}[/tex]
To convert to mixed number, look for the closest number to the numerator that the denominator in the fraction can divide, and write it as the whole number in the mixed fraction, the remainder becomes the numerator of the new fraction:
The closest number to 17 that 3 can divide without a remainder is 15 and 3 can divide 15, 5 times, while the remainder becomes 2
[tex]\therefore \frac{17}{3} = 5\frac{2}{3}\ yards\ of\ cape[/tex]
The population of a town is 15,000. It decreases at a rate of 8% per year. In about how many years
will the population be fewer than 10,000?
Answer:
5
Step-by-step explanation:
If a population is decreasing by 8% we can multiply the population by 92% (1-.08)
which means we have the following equation
population=15000(.92)ⁿ
where n is the number of years
we want to know when the population will be 10,000 so we write
10,000=15,000(.92)ⁿ
.66667=.92ⁿ
a rule we have is
[tex]n=y^x\\log_yn=x[/tex]
which means that
[tex].66667=.92^n\\=log_{.92}.66667[/tex]
compute this and get
4.867
round this up to 5
