A police car leaves a crime scene heading east directly towards the hospital at 72 kilometres per hour. An ambulance leaves a quarter of an hour later and also heads directly east towards the hospital at 81 kilometres per hour. How long will it take for the ambulance to pass the police car?

Answers

Answer 1

Answer:

I'm not sure what the answer is but I will tell you when I get it

Answer 2

The time taken by the ambulance to pass the police car is 2 hours and this can be determined by using the formula of speed.

Given :

A police car leaves a crime scene heading east directly towards the hospital at 72 kilometers per hour. An ambulance leaves a quarter of an hour later and also heads directly east towards the hospital at 81 kilometers per hour.

The following steps can be used in order to determine the time taken by the ambulance to pass the police car:

Step 1 - The distance travel by the car is calculated as:

[tex]d =72\times 0.25 = 18[/tex]

Step 2 - Now, the difference in speed is calculated as:

[tex]\rm \Delta s =81-72 = 9[/tex]

Step 3 - Now, the time taken by the ambulance to pass the police car is calculated as:

[tex]\rm t = \dfrac{d}{\Delta s}[/tex]

[tex]\rm t = \dfrac{18}{9}[/tex]

t = 2 hours

How many different 7-digit positive integers exist? (Note that we don't allow "7-digit" integers that start with 0, such as 0123456; this is actually a 6-digit integer.)

Answers

Answer:

There are 9,000,000 seven-digit positive integers.

Explanation:

For the first digit, we have 9 choices: 1, 2, 3, 4, 5, 6, 7, 8, 9.

For each remaining digit, we have 10 choices: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Each choice is independent of the others. So, the number of total 7-digit positive integers is the product of all the numbers of choices for each digit.

hope it helps

need brainliest......

Since 0 cannot be put as the first digit, there are 9 choices for the first digit, and the next 6 digits have 10 choices. So, there are 9 × 10^6 = 9000,000 numbers.

The illustration below is an example of a semi-regular tessellation.
A. True
B. False

Answers

I think it would be B.False

The illustration below is a semi-regular tessellation is a false statement.

What is Tessellation?

Tessellation is defined as the process of covering of a surface or a plane using the geometric shapes.

One geometric shape will not overlap with the other and there will not be any gaps in between.

There are regular tessellations as well as semi-regular tessellations.

Regular tessellations are the tessellations which are made using only a single type of the polygon to cover the entire surface.

Whereas in semi-regular tessellations, two or more regular polygons are used such that each vertex is the same to cover the surface.

Here, the illustration contains only one type of polygon which are tiled to each other with out any gaps.

It is actually regular tessellation.

Hence the statement that the illustration is semi-regular tessellation is incorrect.

Step-by-step explanation:

use the quadratic square root formula (-b±√(b²-4ac))/(2a) .

a= 3

b=1

c= -5

replace the variables with the numbers listed above and just work out.

x=  1.13 or x= -1.45

Answer:

x = -1/6 + 1/6√61 or x = -1/6 + -1/6 √61

Step-by-step explanation:

3x^2+x-5=0

Using quadratic formula a=3, b=1, c=-5

x = -b ± √b^2 - 4ac / 2a

x = -(1) ± √(1)^2 - 4(3)(-5) / 2(3)

x = -1 ± √61 / 6

x = -1/6 + 1/6√61 or x = -1/6 + -1/6 √61

Step-by-step explanation:

how do I do this I'm confused ​

Answers

Answer:

The interior angles of any triangle equal 180. Triangle CDF is an equilateral triangle meaning all of its angles are the same. 180/3=60

Each angle of triangle CDF is 60

1.m<CDF=60

____________________________________________________________

Isosceles triangles have the 2 base angles the same value while the other angle is another value. IN that instance, the m<a = m<f and the m<a + m<f +  m<b=180°

If we find one of the angles of ABF then we can find all of them.

the m<AFB + 35° + m<CFD + m<DFE=180°

we know that the m<CFD is 60

35+60+m<AFB + m<DFE=180

95+m<AFB + m<DFE=180

LEts look at the angle AFD

AFD is 150° and since m<AFD and the m<DFE are supplementary, the angle of DFE is 30

lets test it:

if m<DFE is 30 then

95+m<AFB + 30=180

125+m<AFB=180

m<AFB=55

therefore the m<BAF would also be 55 and the m<ABF would be 70

m<ABF=70

This is because the interior angles of any triangle add up to 180°

Which trigonometric functions are undefined when x = 0?

Answers

The trigonometric functions that are undefined when x = 0:

cot(x) and cosec(x)

We need to write the trigonometric functions are undefined when x = 0.

We know that the trigonometric functions are : sine, cosine, tangent, cotangent, secant and cosecant.

For angle x the trigonometric functions would be,

sin(x), cos(x), tan(x), cot(x), sec(x), cosec(x)

We know that, when x = 0,

sin(0) = 0 and cos(0) = 1

tan(x) = sin(x) / cos(x)

So, tan(0) = 0

cot(x) = cos(x)/sin(x)

cot(0) = 1 / 0

cot(0) = undefined

Also, sec(x) = 1/cos(x)

so, sec(0) = 1

And cosec(x) = 1/sin(x)

so, cosec(0) = 1/sin(0)

cosec(0) = 1 / 0

i.e., cosec(0) = undefined

Therefore, the trigonometric functions that are undefined when x = 0:

cot(x) and cosec(x)

Step-by-step explanation:

In a 30-60 right triangle the side opposite the 30 degree angle is half the length of the hypotenuse.

x is the side opposite the 30 degree

so x=32/2=16

let's use pythagorean theorem to find y

x^2+y^2=32^2

y^2=32^2-x^2

y^2=1024-16^2

y^2=1024-256
