Write the rule for the arithmetic sequence in slope intercept form: 17,12, 7, 2....

Answers

9514 1404 393

Answer:

  an = -5n +22

Step-by-step explanation:

We observe that the sequence has 17 as its first term and a common difference of 12-17 = -5. Then the general term is ...

  an = a1 +d(n -1)

  an = 17 -5(n -1)

This can be simplified to the desired form.

  an = 17 -5n +5

  an = -5n +22

A major storm has winds speeds that are at least 110 miles per hour.Write and solve an inequality that describes how much greater these wind speeds are than the slowest hurricane

Answers

Answer:

x ≥ 36 miles per hour

Step-by-step explanation:

The speed of a major storm is at least 110 miles per hour while the speed of the slowest hurricane is at least 74 miles per hour.

Let x represent how much greater these wind speeds are than the slowest hurricane. Therefore:

x ≥ 110 miles per hour - 74 miles per hour

x ≥ 36 miles per hour

This means that the winds speed must be 36 miles per hour greater than the slowest hurricane.


2/x+2-1/x=-4/x(x+2)

Answers

I don’t know the answer but get Photomath it’ll help you
Step 1 simply
1+ 2x=-4 ( x + 2 )
Simply again
1+2x=-4x-8
Add 4x to both sides
1+2x+4x=-8
Simply again
1+6x =-8
Subtract 1
6x= -8-1
6x=-9
Divide both sides by 6
Divide x = -9\6
Now the answer is x = -3/2

Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?

Answers

Answer:

We can make the paint amount equal by making sure the parameters have the same unit

Step-by-step explanation:

Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?

To solve the above question, we have the conversion rate:

We can make the paint amount equal by making sure the parameters have the same unit

Hence:

1 gallon (gal) = 3.785411784 kilogram (kg).

Billy had 5 gallons of paint.

1 gallon (gal) = 3.785411784 kilogram (kg).

5 gallons of paint = x

Cross Multiply

x = 5 × 3.785411784 kg

18.92705892 kilograms of paint

Approximately 18.93 Kilograms of paint

Therefore, Billy had 18.93 kg of paint and Bob had 4 kg of paint

I only know the second one, you would use pemdas to break down the equation doing exponents first which would leave you with 2x x 2x x 2x x 2x which would leave you with 16x and the second one would be 4 x 4 which is also 16x so the new equation would be y = 16x - 16x - 3x + 1 which would leave you with an answer of -3x + 1.

The base of a triangle prism shown is an isosceles triangle having a height of H cm, and an area of 36cm squared
The perimeter of the front rectanglular face of the prism is 54cm

state the value of h on the diagram ​

Answers

Answer:

the value of h on the diagram is 9cm

Step-by-step explanation:

area = 1/2 * base * height

a = 1/2*b*h

36=1/2*8*h

36=4h

since the 1/2 will multiply the 8

36=4h

multiply both sides by 4

h=9cm.

2. 753.6

3. 194.2

4. 59.5

5. 4848.3

6. 1818.3

Step-by-step explanation:

We have to use the trigonometric functions sin, cos, and tan. Remember the mnemonic SOH-CAH-TOA when solving these problems. (sinθ=opposite/hypotenuse, cosθ=adjacent/hypotenuse, tanθ=opposite/adjacent)

1. tan(40)=900/x

x=900/tan(40)

x=1072.6

2. tan(37)=x/1000

1000tan(37)=x

753.6=x

3. sin(18)=60/x

x=60/sin(18)

x=194.2

4. sin(48)=x/80

80sin(48)=x

59.5=x

5. tan(22)=x/12000

12000tan(22)=x

4848.3=x

6. tan(33)=x/2800

2800tan(33)=x

1818.3=x

Answers

Answer:

showing that A D to the power of 2 plus D C to the power of 2 equal A C to the power of 2

Step-by-step explanation:

The information about this figure would be used as a step in a proof of the Pythagorean theorem is AC²  = AD²  + CD²

Pythagoras theorem.

The theorem states that the square of the hypotenuse is equal to the sum of the square of the adjacent and opposite

From the given figure, the triangle ADC is right angles. Hence we can apply the theorem on the triangle.

AC = hypotenuseAD = adjacentCD = opposite

According to the theorem:

AC²  = AD²  + CD²

Hence the information about this figure would be used as a step in a proof of the Pythagorean theorem is AC²  = AD²  + CD²
