From x=4 to x=10

When time is also known, distance—the measurement of how far something has travelled in a straight line—can be used to determine speed.

Distance, D = 260 miles

Velocity, V = 80 miles/hour

Time taken, t = distance/velocity

= D/V

slope(m) of the perpendicular line is 1/3.

Slope of a line in mathematics is defined as its steepness. It is calculated as rise(difference of y- coordinates) over run(differences of x- coordinates) .

Two lines which intercept each other at an angle of 90 degree are known as perpendicular lines.

According to the given data and using the formula of perpendicular slope(m1*m2=-1);

Slope(m1) of original line =-3

Let the slope of perpendicular line be m2

m1*m2=-1

Answer:

9-|12x-1|=9

Step-by-step explanation:

Solve for x over the real numbers:

9 - abs(12 x - 1) = 9

Subtract 9 from both sides:

-abs(12 x - 1) = 0

Multiply both sides by -1:

abs(12 x - 1) = 0

Eliminate the absolute value:

12 x - 1 = 0

Add 1 to both sides:

12 x = 1

Divide both sides by 12:

Answer: x = 1/12

Answer:

Answer is B

Step-by-step explanation:

Answer:

C, (0, 9)

Step-by-step explanation:

The y-intercept is when the x-value is 0. We pug in 0 for x, getting f(0) = 3^2=9. The x-coordinate must be 0, and the y-value is 3^2, or 9. The correct answer is (0, 9)

Jonah runs 2 (19/20) laps more than the remaining two days

The fractions that have the same denominator are like fractions, to add like fractions directly, But if the denominators are not the same then we need to change their denominators to the same then we can add the fractions.  

To make denominators as same we need to take the LCM of denominators of two fractions.  

Here we have

Jonah ran 1(3)/(4) laps on Monday

=> 1 3/4 = 7/4 laps

On Tuesday he ran 2(3)/(10) laps

=> 2 3/10 = 23/10 laps

On Wednesday he ran 6(1)/(5) laps

=> 6 1/5 = 31/5 laps

The total number of laps ran combining Monday and Tuesday

= 7/4 laps + 23/10 laps  

= (35 + 46)/20         [ take Lcm of 4, 10 i.e 20 ]  

= 81/20

From the above calculations,

Jonah ran 81/20 laps on combining Monday and Tuesdays

The difference between Wednesday's counted laps and Monday, and Tuesday's counted laps

= 31/5 - 81/20

= (140 - 81)/20             [ Take Lcm of 5, 20 i.e 20 ]    

= 59/20            

= 2 (19/20)

The function that relates the distance traveled to the time is given as follows:

d = vt.

In which v is the average velocity during the time traveled.

The average velocity is calculated as the division of the total distance by the total time, hence the following equation is built to model the proportional relationship between these variables:

v = d/t.

In this problem, we want to relate the distance traveled to the time, hence we have to solve the expression for d, as follows:

d = v x t

d = vt.

(applying cross multiplication to isolate the variable d).

Then it is a proportional relationship in which the average velocity acts as the constant of proportionality.

Answer:

The 72nd term is -708

Step-by-step explanation:

We can conclude that it will take Bob 10 years and 10 months to triple his investment when the compounding is happening semi-annually.

Compounding is the method through which interest is added to both the principal balance already in place and the interest that has already been paid.

Thus, compounding can be thought of as interest on interest, with the result that returns on interest are magnified over time, or the so-called "magic of compounding."

So, the time that will be taken to make the investment triple is:

Amount invested: $2500

Interest rate: 3.4%

Compounding: Semiannually

Now, consider a period of 2 years:

3.4 * 6/12 = 1.7%

The interest rate that is effective will be 1.7%.

Currently, the future value of the compounded rate at 1.7% for a period of 65 factors equals 2.9913.

Consequently, the value will be $2,500 2.9913 = 7,478.25.

65 months divided by six years equals 10.833 years in total.

0.833 * 12 makes up  10 months a year.

Therefore, we can conclude that it will take Bob 10 years and 10 months to triple his investment when the compounding is happening semi-annually.

Answer:

Yes, [tex]\triangle UXC \cong \triangle QRS[/tex]

Step-by-step explanation:

The triangles are congruent by SAS.

The linear function would be y = -4x - 7 which passes through the points (- 2 , 3 ) and ( - 3 , 5 ).

Given that linear function passes through the points (- 2 , 3 ) and ( - 3 , 5 ).

Let the required line would be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

x₁ = -2, y₁ = 3

x₂ = -3, y₂ = 5

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

Substitute values in the equation, we get

⇒ y - 3 = (5 - 1)/(-3 - (-2))[x -(-2)]

⇒ y - 3 = (4)/(-1)[x +2]

⇒ y - 1 = -4(x +2)

⇒ y = -4x - 8 + 1

⇒ y = -4x - 7

Therefore, the linear function would be y = -4x - 7 which passes through the points (- 2 , 3 ) and ( - 3 , 5 ).

A hypothesis test was used to test the hypothesis that men drive faster on average than women.

The p-value in that case was 0.16 and the level of significance used was 0.1

As the p value is greater than level of significance we can say that the null hypothesis is correct

A line parallel to one side of a triangle divides the other two sides proportionally.

What is triangle?

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

Let ΔADE and ΔABC are two triangles.

Given: DE∥BC

To prove:  DB/AD = EC/AE

ΔADE and ΔAC share ∠A

∠A ≅∠A  reflexive property

DE∥BC is given

∠ADE ≅ ∠B   because they are corresponding angles when transversal

            AB cuts parallel lines DE and BC  

ΔADE ∽ ΔABC  a pair of angles in each are congruent.

AB / AD = AC / AE

because corresponding sides of similar triangle's are proportional.

Now subtract 1 from each side

AB / AD - 1 = AC / AE - 1

Combining fractions,

(AB - AD) / AD = (AC - AE) / AE

⇒ DB / AD = EC / AE

What do you mean by fraction?

Fraction represents a part of a whole, or more generally, any number of equal parts. In everyday English, fractions represent how many parts of a particular size are there.

For positive common divisors, the numerator and denominator are natural numbers. The numerator represents the number of equal parts and the denominator shows the number of parts that make up the unit or whole. A zero part can never make up a whole, so the denominator is never zero.

It is given that a recipe calls for 5 teaspoons of seasoning for every 6 batches of chilli.

For  6 batches of chilli, number of teaspoons of seasoning needed = 5

For 1 batch of chilli, number of teaspoons of seasoning needed = 5/6
