Determine the intercepts of the line.
y = 10x - 32
y-intercept: (
z-intercept: (
Answer:
see below
Step-by-step explanation:
y = 10x - 32
To find the x intercept set y =0 and solve for x
0 = 10x -32
Add 32 to each side
32 = 10x
Divide by 10
32/10=10x/10
3.2 = x
To find the y intercept set x =0 and solve for t
y = 10*0 -32
y= -32
Answer:
y.(0,-32)
x.(3.2,0)

Answer:
x=((log(81))/(log(3))+2)/3
Step-by-step explanation:
so what you want to do is get 3x-2 out of the exponent
you can do that by using log
so apply log to both sides and you get
log(81)=(3x-2)log(3)
the 3x-2 is moved in front of the log due to a log rule
then (log(81))/(log(3))=3x-2
(log(81))/(log(3))+2=3x
((log(81))/(log(3))+2)/3=x
then use a calculator to find the exact value

Consider the following ratios and state that whether these ratios forms a proportion?
Case1 - 20 friends to 15 strangers
Case 2 - 4 friends to 3 strangers
A. Yes
B. No
Part B
Find the ratio of the number of friends in Case 1 to the number of friends in Case 2.
Answer:_____________
Note: Type the answer as shown. Ex: (3:8)
Answer:
yes
Step-by-step explanation:
Be cause i whant points 20=15 7213=938401
Part A. Yes, these ratios forms a proportion
Part B- the ratio of the number of friends in Case 1 to the number of friends in Case 2 is 5:1
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
The ratios in cases 1 and 2 form a proportion. IT can be seen by dividing case a by 5 which gives 4:3;
i.e 20:15
If we divide both numerator and denominator by 5, then we have 4/3.
This shows case 1 and 2 have the same proportions of friends to strangers.
Part B; The number of friends in case 1 is 20 while in case 2 is 4.
we have, 20:4
= 20 4
Dividing each by 4, we have 5:1.
Which means that the ratio of friends that in case 1 to case 2 is 5:1.

Ma poate ajuta cineva la acesta problema: pe o drepta g considerati punctele D, R,P si T coliniare in aceasta ordine astfel incat DR=PT=3 cm, iar RP=4cm
Answer:
Givens
[tex]DR=PT=3cm[/tex] and [tex]RP=4cm[/tex]
Points D, R, P and T are collinear.
The image attached shows a representation of this problem.
By sum of segments, we have
[tex]DT=DR+RP+PT[/tex]
Replacing all given values, we have
[tex]DT=3+4+3=10 \ cm[/tex]
Therefore, the segment DT is 10 centimeters long.
Now, we know that point E is the center of segment RP, which means is a middle point, divides the segment equally. So, to prove that segment DT is symmetrical regarding point E, we need to prove that both sides are equal.
[tex]RE=EP=2cm[/tex], by definition of middle point.
By sum of segments, we have
[tex]DR+RE=3+2=5cm\\EP+PT=5cm[/tex]
Which means [tex]DR+RE=\frac{DT}{2}\\ EP+PT=\frac{DT}{2}[/tex].
Therefore, segment DT is symmetrical regarding point E.

By Probability, 0.25 is simulation could you use to answer questions about whether a surfer will see a dolphin.
What does a probability simple definition entail?
A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%. Probability is a measure of how likely or likely-possible something is to happen.
For instance, the chance of flipping a coin and obtaining heads is 1 in 2, as there is only one method to acquire a head and there are a total of 2 potential outcomes (a head or tail). P(heads) = 12 is the formula.
the beach lifeguards, there is a 25% chance.

Financial Literacy: Question 2Gordon opened a savings account with an initial deposit of $1,200.His balance will earn 2.5% simple interest overy year, Balley openeda savings account with an initial deposit of $900. Her balance willearn 3.25% interest compounded annually. The deposits were madeon the same day, and no additional money will be deposited orwithdrawn from the accounts. Which statement about the balances ofGordon's account and Balley's account at the end of 6 years is true?
Answer:
In 6 years form now, the balance in Gordon's account will be = {$1,200 x [1 + (2.5% x 6 years)]} = $1,380
his account will have earned = 2.5% x 6 years x $1,200 = $180 in interests over the six years
In 6 years form now, the balance in Bailey's account will be = $900 x (1 + 3.25%)⁶ = $1,090.39
his account will have earned = $190.39 in interests over the six years
Bailey's account earned more interest than Gordon's, even though his initial balance was much lower. This was due to higher interest rates and more important, because Bailey earned compound interest.

C. The volume of prism A is the same as the volume of prism B.
D. The volume of prism A is greater than the volume of prism B.
Answer:
There is not enough information to compare the volume of the prisms.
Step-by-step explanation:
To find the volume of rectangular prisms, the length , width and height must be given. The volume of rectangular prisms is gotten by multiplying the three dimension: length, width and height which is expressed in cubic units. To compare the two volumes, the three dimensions must be given.
Hence, there is not enough information to compare.
find all solutions to the equation 5sin(3pix)+8=4 in the interval 0 < x < 2
Answer:
First one
Step-by-step explanation:
5sin(3pix)+8=4
5sin(3pix) = -4
sin(3pi x) = -0.8
Basic angle: sin^-1(0.8) = 0.927295218
3pi x = pi+0.927295218, 2pi-0.927295218
3pi x = 4.068887872, 5.355890089, 4.068887872 + 2pi, 5.355890089 + 2pi, 4.068887872 + 4pi, 5.355890089 + 4pi,

In ΔABC, ∠B = 90°, AB = 9 cm and BC = 12 cm. Calculate the length of AC. and area of triangle ABC
Answer:
see explanation
Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
AC² = AB² + BC² , substitute values
AC² = 9² + 12² = 81 + 144 = 225 ( take the square root of both sides )
AC = [tex]\sqrt{225}[/tex] = 15 cm
-------------------------------------------
The area of Δ ABC is calculated as
A = [tex]\frac{1}{2}[/tex] × BC × AB = [tex]\frac{1}{2}[/tex] × 12 × 9 = 6 × 9 = 54 cm²
If you wanted to safely climb a 50-foot wall, what’s the shortest ladder you’d be willing to use? Explai
Answer:
If I wanted to safely climb a 50 foot wall, I would use a 51 foot ladder.
Step-by-step explanation:
If I wanted to climb a fifty foot (50 ft) wall, I would use a fifty one foot (51 ft) ladder because the safe way to position a ladder against the wall requires that I leave one foot (1 ft) distance from the base of the ladder to the wall. That way, the ladder won't be too close nor too far from the wall.

Jim is entering kennywood with 5 of his friends. At the gate they must go through a turnstile one at a time. How many ways can Jim and his friends go through the turnstile
Answer:
6 ways
Step-by-step explanation:
The total number of people we have entering Kennywood is 6, since it’s Jim with 5 of his friends.
Now, we can only have movement through the game one at a time
The number of ways they can move through the gate one at a time is 6C1 ways
and that is mathematically;
if we are to select a number of r items from a total of n, the number of combinations or ways is;
nCr = n!/(n-r)!r!
Applying these to the problem at hand, we have
6!/(6-1)!1! = 6!/(5!)(1!) = (6 * 5!)/5! = 6 ways
