At noon the temperature was -10° F. Over the next 4 hours the temperature went up 12°. Then every hour until 10 pm the temperature dropped 2°. What was the temperature at 10 pm?

Answers

Answer:

-10 degrees

Step-by-step explanation:

at noon the temp was -10. -10 + 12 = 2 and that is at 4 o'clock 2- 6 hours ( time until 10 pm) x 2. 2 - 12 = -10.

Answer: 0º F.

Step-by-step explanation:

Noon = 12 pm

At Noon it was -10º F, over the next 4 hours it went up to 12º F.

Noon + 4 hours = 4 pm

The temperature dropped 2º F every hour until 10 pm which means for 6 hours the temperature dropped.

6x2º F = 12º F which means the temperature dropped by 12º F.

12º F - 12º F = 0º F

The triangles are congruent because they are the same shape, size, and angle measure. The lines on the angles show that two angles have the same measure. The line on the line segments shows that it hads the same length.

Martina opens a savings account with an initial deposit and makes no other deposits or withdrawals. She earns interest on her initial deposit. The total amount of money in her savings account at the end of each year is represented by the sequence shown.
100, 105, 110.25, ...
Which recursive formula can be used to determine the total amount of money earned in any year based on the amount earned in the previous year?

A. f(n + 1) = f(n) + 5
B. f(n + 1) = 5f(n)
C. f(n + 1) = 1.05f(n)
D. f(n + 1) = 0.05f(n)

Answers

1.05 should be it

Step-by-step explanation:

In a recursive formula, each term of the sequence is found by using the previous term. In this case, the sequence is geometric because we are multiplying each term by the same constant, called a common ratio.

To find this common ratio, we find the percent of change between terms. We do this by using the formula

% change = (amount of change)/(original amount)

The amount of change between the first two terms is 105-100 = 5. This makes the percent change

5/100 = 0.05

The amount of change between the second two terms is 110.25-105 = 5.25. This makes the percent change

5.25/105 = 0.05

However, the common ratio in the sequence is not 0.05. This is because multiplying by this decimal would make the terms decrease instead of increasing. In this case, we are taking 100% of the number and adding an extra 5% (0.05 = 5%); this makes our common ratio 105% = 1.05.

This gives us the recursive formula

The members of a small town's local arts council are selling raffle tickets. The art council decides that the top three raffle ticket sellers will share a portion of the profits. The second-place seller will receive twice as much as the third-place seller. The first-place seller will receive $20 more than second-place seller. How much will each of the top three sellers receive if the profit portion they will share is $200?

Answers

Answer:

Profit shall be distributed as :

First seller = $92

Second seller = $72

Third seller = $36

Step-by-step explanation:

Let the first seller be A

Second seller be B

Third seller be C

Let the profit of third price seller C = "x"

Profit of B = 2x

Profit of A = 2x + $20

Total profit received by all of them = $200

$200 = (2x + $20) + (2x) + (x)

$200 = 5x + $20

$180 = 5x

x = $36

Therefore profit for 3rd seller = $36

Profit for second seller = $36 [tex]\times[/tex] 2 = $72

Profit for first seller = $72 + $20 = $92

x = 29

Step-by-step explanation:

The sum of the 3 angles is 180 degrees since it is a straight line

x-1 + 3x+2 + 2x+5 = 180

Combine like terms

6x +6 = 180

Subtract 6 from each side

6x+6-6= 180-6

6x =174

Divide y 6

6x/6 =174/6

x = 29

What is the average rate of change of the line?

Answers

Answer:

- 12

Step-by-step explanation:

The slope of the line is a measure of the average rate of change

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = - 12(x + 4) ← is in point- slope form

with slope m = - 12 ← average rate of change

please help

Answers

Answer:

m∠b + m∠e = 180°

Step-by-step explanation:

Lines x and y are the parallel lines and a transversal line is intersecting these lines.

∠b ≅ ∠h [Vertical angles]

∠h ≅ ∠f [Corresponding angles]

Therefore, ∠b ≅ ∠f [Congruent angles]

m∠f + m∠e = 180° [Supplementary angles]

m∠b + m∠e = 180° [Since, ∠b ≅ ∠f]

Therefore, equation representing the relation between ∠b and ∠e is,

m∠b + m∠e = 180°

The required equation that represents the relationship between b and e is m<b + m<e = 180

From the given diagram, we can see that the line x and y are cut by a transversal. This shows that the following statements are true;

m<b and m<g are supplementary i.e m<b + m<g = 180

Also m<b and m<f are equal (alternate interior angle)

m<b = m<d (vertically opposite angle)

Also, since m<d and m<e are supplementary angles (angle on a straight line), then m<b and m<e are also supplementary

Hence the required equation that represents the relationship between b and e is m<b + m<e = 180

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Translation is the movement of a point up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units right and b units down, the new location would be at A(x + a, y - b).

Since the vertex Y(-4, 2) was translated to Y'(0, -3), hence the triangle was translated 4 units to the right (-4 + 4 = 0) and 5 units down (2 - 5 = -3). This can be represented by the mapping:

(x, y) ⇒ (x + 4, y - 5)

Therefore to find x and z coordinates, use the mapping:

(x, y) ⇒ (x + 4, y - 5)

Answers

Answer:

a(t) = 487(1/2)^(t/36)a(5) = 442.302 kg

Step-by-step explanation:

The exponential function for half-life problems is easily written using 1/2 as the base of the exponent.

present value = (initial value) × (1/2)^(t/(half-life))

Then the amount (a) remaining after t days is ...

a(t) = 487 × (1/2)^(t/36)

After 5 days, the amount remaining is ...

a(5) = 487×(1/2)^(5/36) ≈ 442.302 kg

_____

Some folks like their exponential function to be written using e as the base for the exponent. Here, that would be ...

a(t) = 487·e^(-0.019254t)

where the constant in the exponent is -ln(2)/36.
