Solve for t in the formula above to obtain a formula expressing tas a function of V.V= 14.5 – 1.3t t=

Answers

Answer 1

Given the equation:

[tex]V=14.5-1.3t[/tex]

We want to make t the subject of formula;

firstly, let us subtract 14.5 from both sides.

[tex]\begin{gathered} V=14.5-1.3t \\ V-14.5=14.5-14.5-1.3t \\ V-14.5=-1.3t \\ -1.3t=V-14.5 \end{gathered}[/tex]

Then let's divide both sides by -1.3;

[tex]\begin{gathered} \frac{-1.3t}{-1.3}=\frac{V-14.5}{-1.3} \\ t=\frac{-V+14.5}{1.3} \end{gathered}[/tex]

What is Pythagoras's Theorem?

In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

We can proceed to use this to find the distance from point a to point b assuming he ran through a straight line.

Mathematically, the theorem can be expressed as

An industrial machine made 1,629 cans of diet sodas and 6 times as many
regular sodas over the course of 46 minutes. The regular sodas were then
placed into 3 shipping boxes with each shipping box containing the same
number of sodas. How many regular sodas were in each shipping box.

Answers

Each of the shipping boxes contains 2172 cans of regular soda.

Ratios and fractions are the main bases on which proportion is explained. Two ratios are equal when they are expressed as a fraction in the form of a/b, ratio a:b, and then a proportion.

The industrial machine made a total of 1629 cans of diet soda which is 6 times as much regular soda in 46 minutes.

Then, the total number of regular sodas made will be:

R = 4 × Total number of diet soda

R = 4 × 1629 cans

R = 6516 cans

The regular sodas were packed in 3 shipping boxes with each having the same number of soda cans.

Therefore, the number of cans of regular sodas in each box will be:

N = 6516/3

N = 2172 cans

There are 2172 cans of regular sodas in each shipping box.

Helen has a 4 kilometer-head start on París how long will it take París to catch Helen if helen travels at 6 kilometers per hour and París traveled at 8 km per hour

Answers

Assume "h" = number of hours traveled

Helen's speed = 6km per hour and is 4km advanced than Paris

Paris' speed = 8km per hour

Therefore, we can form the following equations:

a. Helen's distance traveled = 4km + 6km (h) = 4 + 6h

b. Paris' distance traveled = 8km (h) = 8h

For us to determine how long will Paris be able to catch Helen, we'll have to assume they have traveled the same distance. In this case:

Helen's distance traveled = Paris' distance traveled

[tex]\begin{gathered} 4+6h=8h \\ \text{Subtrach 6h on both sides of the equation.} \\ 4+6h-6h=8h-6h \\ 4=2h \\ \text{Divide two on both sides.} \\ \frac{4}{2}=\frac{2h}{2} \\ 2=h \end{gathered}[/tex]

Therefore, it will take 2 hours for Paris to catch up with Helen which is at 16km.

The coordinates of P is;

[tex]P=(7,9)[/tex]

We want to find the coordinate of P such that P partitions AB in the ratio 5:1.

Given the coordinates of A and B as;

[tex]\begin{gathered} A(2,4) \\ B(8,10) \end{gathered}[/tex]

Let (x,y) represent the coordinates of point P;

[tex]\begin{gathered} \frac{x-2}{8-x}=\frac{5}{1} \\ x-2=5(8-x) \\ x-2=40-5x \\ x+5x=40+2 \\ 6x=42 \\ x=\frac{42}{6} \\ x=7 \end{gathered}[/tex][tex]\begin{gathered} \frac{y-4}{10-y}=\frac{5}{1} \\ y-4=5(10-y) \\ y-4=50-5y \\ y+5y=50+4 \\ 6y=54 \\ y=\frac{54}{6} \\ y=9 \end{gathered}[/tex]

Find the equation for the tangent to the curve of f at the point:f(x) = (3x+1)² , x = -1

Answers

The eqaution of the tangent at the point x = -1 is:

[tex]y=-12x-8[/tex]

To solve this, first, we need to find the value of y when x = -1:

[tex]f(-1)=(3\cdot(-1)+1)^2=(-3+1)^2=(-2)^2=4[/tex]

Then we want to find the equation of the tangent at the point (-1, 4)

The next step is to find the derivative of the equation, because the derivative thell us the slope of the tangent line at a certain point:

[tex]\begin{gathered} f(x)=(3x+1)^2 \\ f^{\prime}(x)=2(3x+1)\cdot3=6(3x+1)=18x+6 \\ \\ f^{\prime}(x)=18x+6 \end{gathered}[/tex]

Now that we have the derivative, let's calculate the slope of the tangent like in the point (-1, 4). To do this, we evaluate the derivative in x = -1:

[tex]f^{\prime}(-1)=18\cdot(-1)+6=-18+6=-12[/tex]

The slope of the tangent line is -12.

Now we have all the necessary things to construct the equation of a line: we have the slope (-12) and a point (-1, 4).

The slope-point form of a line is:

[tex]\begin{gathered} y=m(x-x_0)+y_0 \\ \end{gathered}[/tex]

Where m is the slope and x0, y0 are the x and y coordinates of a point

Then:

[tex]\begin{gathered} \begin{cases}m=-12 \\ x_0=-1 \\ y_0=4\end{cases} \\ y=-12(x-(-1))+4=-12\mleft(x+1\mright)+4=-12x-12+4=-12x-8 \end{gathered}[/tex]

And that's the equation of the line y = -12x - 8

We have a total of 10 cards.

From these 10 cards, three cards are number 4, so the probability of choosing a number 4 is P = 3/10.

Calculating the probability for each option, we have:

A. Odd number

There are 6 odd numbers among the cards, so the probability is P = 6/10

B. Prime number

There are 3 prime numbers among the cards, so the probability is P = 3/10

C. Another even number

There are 4 even numbers among the cards, so the probability is P = 4/10

D. An odd number less than 7.

There are 3 odd numbers less than 7, so the probability is P = 3/10

The bigger probability is for an odd number, therefore the correct option is A.

Step-by-step explanation

The volume of a rectangular prism is calculated as follows:

where w is the width, h is the height and l is the length of the prism.

The hutch is made up of two rectangular prisms, one with a width of 1 1/3 ft, a height of 2 1/2 ft, and a length of 4 ft. The other one has a width of 2 2/3 ft, a height of 2 1/2 ft, and a length of 4 ft.

To calculate the volume of the hutch, first, we need to calculate the volume of each prism, and then add them.

The volume of the smaller prism is:

Parents plan to ship some items to their child who is attending college out of town. Thestudent definitely needs towels, which weigh 9 pounds. The cost is $45 to ship up to 15pounds.a. Write and solve an inequality that represents how many pounds the parents can add tothe shipment without having to pay additional shipping costs

Answers

Answer

The inequality equation is

(9 + x) ≤ 15

The solution is

x ≤ 6 pounds

The number of pounds that the parents can add to the shipment without having to pay additional shipping costs is less than or equal to 6 pounds.

Step-by-step Explanation

The question wants us to write and solve an inequality that represents how many pounds the parents can add to the shipment without having to pay additional shipping costs.

The towels needed by the student already weigh 9 pounds.

The maximum weight of shipment that is allowable for a payment of $45 is 15 pounds.

Let the additional weight that the parents can add to the shipment without having to pay additional shipping costs be x.

Since the maximum weight allowable is 15 pounds, the 9 pounds already on ground plus the additional x pounds must not exceed 15 pounds. That is, that total weight must always be less than or equal to 15 pounds.

Mathematically,

(9 + x) ≤ 15

This is the inequality equation. We can now solve this

(9 + x) ≤ 15

Subtract 9 from both sides

(9 + x) - 9 ≤ 15 - 9

9 + x - 9 ≤ 6

x ≤ 6

Hence, the number of pounds that the parents can add to the shipment without having to pay additional shipping costs is less than or equal to 6 pounds.

Answers

√15, and -√15

1) Considering the equation below, let's solve it:

[tex]\begin{gathered} x^2=15 \\ \sqrt[]{x^2}=\sqrt[]{15} \\ x=\sqrt[]{15},\text{ -}\sqrt[]{15} \end{gathered}[/tex]

2) So the answer is √15, and -√15

Since (√15)² = 15 and (-√15)²=15
