Answer:

-1.4

Step-by-step explanation:

h(2) = h(2-1) + 1.8

= h(1) + 1.8

= -5 + 1.8

= -3.2

h(3) = h(3-1) + 1.8

= h(2) + 1.8

= -3.2 + 1.8

= -1.4

As per the given expression h(n)=h(n−1)+1.8, then the value of h(3) is -1.4.

In this explanation, we will calculate the value of h(3) using the given recursive formula h(n) = h(n-1) + 1.8 with the initial condition h(1) = -5. We will follow the iterative approach to find the value of h(3) by step-by-step calculations.

We are given the recursive formula h(n) = h(n-1) + 1.8, where h(1) = -5. Let's find the value of h(3) using this formula.

Step 1: Calculate h(2)

To find h(2), we use the recursive formula:

h(2) = h(1) + 1.8

h(2) = -5 + 1.8

h(2) = -3.2

Step 2: Calculate h(3)

Now, to find h(3), we again use the recursive formula:

h(3) = h(2) + 1.8

h(3) = -3.2 + 1.8

h(3) = -1.4

Answer:

the number of caffeine still in his system by 9:00 am is 192 mg.

Step-by-step explanation:

given information

the mass of initial caffein, m₁ = 300 mg

time, t = 9 - 6 = 2 hours

metabolised = 18%/hour = 0.18/h = 0.18 x 300 mg = 54 mg/h

the student metabolised the caffeine 54 mg/h. thus from 6 am to 9 am the caffeine metabolised is

metabolised in 2 hr = 2 x 54

                                 = 108 mg

the remaining caffeine = initial caffeine - metabolised caffeine

                                      = 300 - 108

                                      = 192 mg

Answer:

The correct answer is 138 mg.

Step-by-step explanation:

To understand this problem we must first analyze it.

We know that the student's body metabolizes 18% of the caffeine ingested every hour.

Therefore we can solve that percentage to already have the number of metabolized caffeine per hour:

(300. 18): 100 =

5400: 100 = 54 mg

We now know that the student's body will metabolize 54 mg of caffeine per hour.

The question is much caffeine is still in his system by 9:00 am?

From 6:00 am to 9:00 am we have 3 hours of difference: 3 . 54 = 162

In three hours 162 mg of caffeine were already processed by his body, therefore, it still needs to be metabolized: 300 - 162 = 138 mg.

The best estimate for what their down payment will be $5850

A conventional loan is any mortgage loan that is not insured or guaranteed by the government.

Given that, The Franzes are purchasing a home for $195,000, and they are using a conventional loan.

We know, the minimum down payment required for a conventional mortgage is 3%

So, 3% of $195,000 = 195,000x3/100

= 5850

Hence, The best estimate for what their down payment will be $5850

Answer:

x = -6 ; y = 11

x = 3 ; y = 5

x = 15 ; y = -3

x = -12 ; y = 15

Step-by-step explanation:

y = -(⅔)x + 7

x = -6

y = -(⅔)(-6) + 7

y = 11

5 = -(⅔)x + 7

-2 = -(⅔)x

x = 3

y = -(⅔)(15) + 7

y = -3

15 = -(⅔)x + 7

8 = -(⅔)x

x = -12

The expression which is false in determining the volume of the cylinder is given by V₁ = π . 3 . 12²

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is

Volume of Cylinder = πr²h

Surface area of cylinder = 2πr ( r + h )

where r is the radius of the cylinder

h is the height of the cylinder

Given data ,

Let the volume of the 12 cylinders be V

Let the height of the cylinder be h = 1 cm

Let the radius of the cylinder be r = 3 cm

Now , Volume of Cylinder = πr²h

On simplifying , we get

Volume of the cylinder V = 12 x ( π x 3² x 1 )

Volume of the cylinder V = π x 3² x 12 cm³

Volume of the cylinder V = 108π cm³

So , the expression V₁ = π . 3 . 12² is false and cannot be used to determine the volume of the cylinder

Hence , the volume of cylinder is 108π cm³

[tex]f(x)=417(1.0375)^{x}[/tex]

Step-by-step explanation:

This question is not complete; please find the question attached.

Sales of cell phones at the store is growing at the rate of 3.75% per month which reveals that the monthly sales of cell phone is growing exponentially.

Sales per month will be represented by the growth function,

[tex]f(x)=A(1+\frac{r}{100})^{x}[/tex]

Where f(x) = Monthly sales

A = Sales in the first month

r = rate of increase in the sales

x = Duration or time

Fro the given question,

A = 417,  r = 3.75

So the function showing the monthly sales will be,

[tex]f(x)=417(1+\frac{3.75}{100})^{x}[/tex]

[tex]f(x)=417(1.0375)^{x}[/tex]

Answer:

The answer is x = 13.

Step-by-step explanation:

first, move the constant to the right and change its sign, (+15)

3.75 x = 63.75 -15

next, subtract the numbers, (65.75 -15)

3.75x = 48.75

then, divide both sides of the equation by 3.75,

final answer, x = 13

Answer:

x = 13

Step-by-step explanation:

to solve this just simply collect the like terms and divide both sides by the coefficient of x

solution

3.75x +15 = 63.75

3.75x = 63.75 -15

3.75x = 48.75

divide both sides by the coefficient of x which is 3.75

3.75x/3.75  = 48.75/3.75

x = 13

Answer:

x=40

Step-by-step explanation:

What the problem is telling you is that the unlabeled angle is the same as the 70 degree angle. Since all the angles of a triangle add up to 180 degrees. First take 70+70, which equals 140. Now take the 180-140=40 ,so 40 would be the missing angle.

Final answer:

In an isosceles triangle, the angles opposite the congruent sides are congruent. To find the value of x in the triangle, we can set up an equation using the fact that the sum of the angles in a triangle is always 180 degrees. Simplifying the equation, we can find a value for x.

Explanation:

In an isosceles triangle, the angles opposite the congruent sides are congruent. Let's assume that the value of the unknown angle is x.

Since the triangle is isosceles, the other two angles are congruent. Let's call them a and a.

The sum of the angles in a triangle is always 180 degrees. Therefore, we can write the equation: x + a + a = 180.

Simplifying the equation, we get: 2a + x = 180.

Since the other two angles are congruent, we can say that: 2a = 180 - x.

Dividing both sides of the equation by 2, we find: a = (180 - x)/2.

Therefore, the value of x in the triangle is (180 - a)/2.

To find out how many cherries Rachel picked, the mixed numbers are converted to improper fractions, multiplied, and the result is converted back to a mixed number. Rachel picked 3 11/15 pounds of cherries.

The question asks how many cherries Rachel picked, given that Melissa picked 1 3/5 pounds of cherries and Rachel picked 2 1/3 times more than Melissa. To find this out, we need to convert the mixed numbers into improper fractions, multiply and then convert back to a mixed number if necessary.

First, convert Melissa's cherries to an improper fraction: 1 3/5 = 8/5. Next, convert the number of times more Rachel picked: 2 1/3 times more = 7/3. Now, calculate Rachel's cherries: (8/5) * (7/3) = 56/15. Finally, convert 56/15 to a mixed number: 56/15 is 3 11/15. So, Rachel picked 3 11/15 pounds of cherries.
