State the point on the line y - 18 = 71.3(x +98)
Please explain how you got your answer, thank you.
9514 1404 393
Answer:
(-98, 18)
Step-by-step explanation:
We recognize the equation as being in the "point-slope" form.
y -k = m(x -h) . . . . . . . a line with slope m through point (h, k)
__
Comparing this form to the given equation, we identify the parameters as ...
k = 18, m = 71.3, h = -98
The point on this line is (h, k) = (-98, 18).

34. The amount of money in an account with continuously compounded interest is given by the formula 1
4 Por, where is the principal, / is the annual interest rate, and / is the time in years, Calculate to the
nearest hundredth of a year how long it takes for an amount of money to double if interest is compounded
continuously at 6,2%Round to the nearest tenth,
11.2 y
A
1 0.0 %
O
4
Answer:
Step-by-step explanation:
I have no idea what formula that is you're using but the one I teach in both algebra 2 and in precalculus for continuous compounding is
[tex]A(t)=Pe^{rt}[/tex]
where A(t) is the amount after the compounding, P is the initial investment, ee is Euler's number, r is the interest rate in decimal form, and t is the time in years. If our money doubles, we just have to come up with a number which will be P and then double it to get A(t). It doesn't matter what number we pick to double, the answer will come out the same regardless. I started with 2 and then doubled it to 4 and filled in the rest of the info given with time as my unknown:
[tex]4=2e^{(.062)(t)}[/tex]
Begin by dividing both sides by 2 to get
[tex]2=e^{.062t}[/tex]
The only way we can get that t out of its current position is to take the natural log of both sides. Natural logs have a base of e, so
[tex]ln_e(e)=1[/tex] This is because they are inverses of one another. Taking the natural log of both sides:
[tex]ln2=.062t[/tex] Now divide by .062 to get
t = 11.2 years

Jason has 34 strawberry scones and 85 raspberry scones.He wanted to make as many identical bags of scones as possible.Each bag should have an equal number of strawberry scones and an equal number of raspberry scones.What is the greatest number of bags Jason can fill?
Answer: 17
Step-by-step explanation:
We are told Jason has 34 strawberry scones and 85 raspberry scones and that he wanted to make as many identical bags of scones as possible and that each bag should have an equal number of strawberry scones and an equal number of raspberry scones.
To calculate greatest number of bags Jason can fill, we find the factor of 34 and 85 and choose the highest that's common to both.
Factor of 34 = 1, 2 , 17, and 34
Factor of 85 = 1, 5, 17, and 85.
Highest common factor = 17
The answer is 17

4x + 5 = 6x – 7
solve for x
Answer:
x = 6
Step-by-step explanation:
4x + 5 = 6x - 7 subtract 4x from both sides
5 = 2x - 7 now add 7 to both sides
12 = 2x finally divide both sides by 2
x = 6

Step-by-step explanation:
You have to add 1/4 and 3/4 and I mean you do 3+1=4 then add 4+1=5
Or you can add 1/4+3/4 which is 4/8 then do 4/8+1 whole that equals 1.5

Step-by-step explanation:
47.9 is what percent of 152?
A)3.2%
B)31.5%
C)0.32%
D)317.3%
Answer: B
Step-by-step explanation:
Step 1: We make the assumption that 152 is 100% since it is our output value.
Step 2: We next represent the value we seek with x
Step 3: From step 1, it follows that 100%=152
Step 4: In the same vein, x%=47.9
Step 5: This gives us a pair of simple equations:
100%=152(1).
x%=47.9(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x% = 152/47.9
x= 31.5

Consecutive interior angles are...
A. Complementary
B. Supplementary
C. Congruent
D. Colinear
Answer:
Consecutive interior angles will be supplementary
Step-by-step explanation:
As we know that a transversal line is a straight line which tends to intersect two or more parallel lines.
Consecutive interior angles are interior angles that are on the same side of the transversal line. Their sum is 180°.
Hence, Consecutive interior angles will be supplementary
For example, let ∠A and ∠B be the two consecutive interior angles.
As the sum of Consecutive interior angles is 180°, hence they are supplementary.
so the equation becomes
∠A + ∠B = 180°
Let suppose <A and <B are both consecutive interior angles.
Let ∠A is 110°, and we have to determine ∠B.
As the sum of Consecutive interior angles is 180°,
110° + ∠B = 180°
∠B = 180° - 110°
= 70°
so 70° + 110° = 180°
Therefore, Consecutive interior angles will be supplementary
