Points A and B are 200 mi apart.

Answers

Answer 1
okay and what about it?
Answer 2

Answer:

17*200/17+83

Step-by-step explanation:

Points A and B are 200 mi apart. A cyclist started from point A and a motorcyclist started from point B, moving towards each other. The speed of the cyclist was 17 mph, the speed of motorcyclist was 83 mph. At what distance from point A will they meet?

The distance under the question is 17*200/17+83= 17*2 = 34 miles.

17+83 = 100 mph in the denominator is the relative speed of the participants,  the rate of decreasing the distance between them.

200/17+83=200/100= 2 hours is the time before they meet.

therefore  17*200/17+83 is the time before they meet

Answer:

The measure of the largest angle is 72º.

Step-by-step explanation:

We will first solve for x. We know that the sum of the interior angles of a triangle is 180º, so 15x + 21x + 24x is equal to 180º. This means that 60x = 180º, so x = 3º. The largest angle is 24x, which is 72º.

p(1)-P(-1)
divides it int

Answers

Answer:

[tex]p(1) - p(-1) =8[/tex]

Step-by-step explanation:

Given

[tex]p(m) = 4m^3 + 3[/tex]

Required

[tex]p(1) - p(-1)[/tex]

First, we calculate p(1)

Substitute 1 for m in [tex]p(m) = 4m^3 + 3[/tex]

[tex]p(1) = 4(1)^3 + 3[/tex]

[tex]p(1) = 4*1 + 3[/tex]

[tex]p(1) = 4 + 3[/tex]

[tex]p(1) = 7[/tex]

Next, we calculate p(-1)

Substitute -1 for m in [tex]p(m) = 4m^3 + 3[/tex]

[tex]p(-1) = 4(-1)^3 + 3[/tex]

[tex]p(-1) = 4*-1 + 3[/tex]

[tex]p(-1) = -4 + 3[/tex]

[tex]p(-1) = -1[/tex]

[tex]p(1) - p(-1)[/tex] is then calculated as:

[tex]p(1) - p(-1) = 7 - (-1)[/tex]

[tex]p(1) - p(-1) = 7+1[/tex]

[tex]p(1) - p(-1) =8[/tex]

please help solve this.​

is the square root of 10 greater less than or equal to 5

Answers

Answer: it is less then 5

Step-by-step explanation:

Because 10 lies between two consecutive perfect squares (in increasing order) 10 is located between the square roots of these two numbers. This means that 10 is located between 10 is less than 5.

Answer:

less than

Step-by-step explanation:

finding the square root of 10 is a bit complicated because the number 10 is not a perfect square which has a number 0 at it's unit Place. Finding the square root of a number is the reverse process of squaring the number. we can find the square root of 10 using two methods one method is to find the root value using unit places and another method is with the help of long division method.

What is the average time in seconds between 2.15 2.05 2.02

Answers

Answer:

[tex]Average = 2.073[/tex]

Step-by-step explanation:

Given:

Time: 2.15, 2.05, 2.02

Required

Determine the average

Average is calculated as thus:

[tex]Average = \frac{\sum x}{n}[/tex]

In this case:

[tex]\sum x = 2.15+2.05+2.02[/tex]

and

[tex]n = 3[/tex]

[tex]Average = \frac{\sum x}{n}[/tex] becomes

[tex]Average = \frac{2.15+2.05+2.02}{3}[/tex]

[tex]Average = \frac{6.22}{3}[/tex]

Can someone pls help me find the second derivative of this. I need to find the concave up and down intervals but I’m having trouble getting the second derivative

Answers

Starting from

[tex]f(x)=\dfrac14(x+1)^{\frac83}-4(x+1)^{\frac23}[/tex]

take the first derivative using the power and chain rules:

[tex]f'(x)=\dfrac83\cdot\dfrac14(x+1)^{\frac83-1}-\dfrac23\cdot4(x+1)^{\frac23-1}[/tex]

[tex]f'(x)=\dfrac23(x+1)^{\frac53}-\dfrac83(x+1)^{-\frac13}[/tex]

Now take the second derivative:

[tex]f''(x)=\dfrac53\cdot\dfrac23(x+1)^{\frac53-1}-\left(-\dfrac13\right)\cdot\dfrac83(x+1)^{-\frac13-1}[/tex]

[tex]f''(x)=\boxed{\dfrac{10}9(x+1)^{\frac23}+\dfrac89(x+1)^{-\frac43}}[/tex]

Optionally, you can condense the second derivative a bit by factoring out [tex]\frac89(x+1)^{-\frac43}[/tex], which gives

[tex]f''(x)=\dfrac89 (x+1)^{-\frac43} \left(80(x+1)^{\frac63}+1\right)[/tex]

[tex]f''(x)=\dfrac89 (x+1)^{-\frac43} \left(80(x+1)^2+1\right)[/tex]

[tex]f''(x)=\dfrac89 (x+1)^{-\frac43} \left(80x^2+160x+81\right)[/tex]

Answers

Answer:

[tex]\frac{8}{14} = \frac{14}{x+2}[/tex]  (since they're similar, set them up as a proportion to find x)

14*14 = 8(x+2) (cross multiply, solve the left side, and distribute the right side)

196 = 8x +16 (subtract 16 from both sides)

180 = 8x (divide both sides by 8)

The decay of 277 mg of an isotope is described by the function

A(t)= 277e-0.019t,

where t is time in years.

To find the amount left after 64 years,

We substitute t = 64 in the expression.

A(t=64)= 277e-0.019(64)

or A(t=64) = 277 * e-1.216

                = 277 * 0.29

Answer:

Table (4)

Step-by-step explanation:

If data in the given tables show the proportional relation then they will follow the rule,

y = kx

k = [tex]\frac{y}{x}[/tex]

where 'k' = proportionality constant

From table (1),

k = [tex]\frac{2}{1}[/tex] = 2

k = [tex]\frac{3}{2}=1.5[/tex]

But 2 ≠ 1.5

So the data in the table (1) is not proportional.

Table (2)

k = [tex]\frac{0}{2}=0[/tex]

k = [tex]\frac{2}{4}=0.5[/tex]

Therefore, data in the table is not proportional.

Table (3)

k = [tex]\frac{1}{0}[/tex] = Not defined

k = [tex]\frac{3}{2}=1.5[/tex]

Data is not proportional.

Table (4)

k = [tex]\frac{y}{x}=\frac{-6}{-2}[/tex]

  = 3

k = [tex]\frac{3}{1}=3[/tex]

3 = 3

Therefore, data given in table (4) represents the proportional relationship.

Step 1: Flip the equation.

1.5x−10=35

Step 2: Add 10 to both sides.

1.5x−10+10=35+10

1.5x=45

Step 3: Divide both sides by 1.5.
