Answer 1

taking a peek at the picture, we can see that the U-turn or vertex occurs at the point (2 , -9), and we can also see that the graph passes through the point say (5 , 0).

Find the values of x and y in the triangle below.
(Please hurry)

Answers

Answer:

x = 10.4

y = 9

Step-by-step explanation:

Suppose the triangles are similar

x/26 = 8/20 (side lengths must be proportional) cross multiply expressions

20x = 208 divide both sides by 20

x = 10.4

same goes for y

6/(6+y) = 8/20 cross multiply expressions

120 = 8y + 48 subtract 48 from both sides

72 = 8y divide both sides by 8

9 = y

1 km = 0.62 mi. The distance between Lowell and Shelby is 285
miles. How many kilometers is this?
Round your answer to the nearest whole kilometer.

Answers

Answer:

459

Step-by-step explanation:

Since to find out mile to kilometer you divide the mile by 1.609 would equal  458.66304 and rounding it to the nearest whole kilometer is 459 there is you answer.

The distance between Lowell and Shelby is approximately 460 kilometres.

Given that information:

1 km = 0.62 miles

Also given the distance between Lowell and Shelby is 285 miles.

To convert miles to kilometres, use the conversion factor:

1 mile = 1.60934 kilometres

Now calculate the distance in kilometres as follows:

Distance in kilometres = 285 miles × 1.60934 km/mile

Distance in kilometres ≈ 459.7 kilometres.

Now, round the answer to the nearest whole kilometre as follows:

Distance in kilometres ≈ 460 kilometres.

Hence, the distance between Lowell and Shelby is approximately 460 kilometres.

How the end behavior of a function f(x) is found?

It is found by it's limits as x goes to infinity. On the left, it is given by:

954.56 in.3. Find the volume of the solid. Use 3.14 for 1. What
mistake might the student have made?

Answers

The volume of the solid is 753.6 in³

Volume

Volume is the amount of space occupied by a three dimensional figure or shape.

The volume of the solid with hole = (π * (8/2)² * 16) + (1/3)(π * (8/2)² * 9)= 954.56 in³

Volume of hole =  (π * (2)² * 16) = 200.96 in³

Volume of solid = 954.56 in³ - 200.96 in³ = 753.6 in³

A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and test 39 ​tablets, then accept the whole batch if there is only one or none that​ doesn't meet the required specifications. If one shipment of 4000 aspirin tablets actually has a 5​% rate of​ defects, what is the probability that this whole shipment will be​ accepted? Will almost all such shipments be​ accepted, or will many be​ rejected?

Answers

Probabilities are used to determine the chances of a shipment being accepted or rejected

The probability that a shipment will be accepted is 0.4129Many shipments will be rejected

How to determine the probability

The rate of defect is 5%.

So, the probability that a tablet is not defect is 95%

The probability that there is no defect out of the 39 selected tablets is:

[tex]P(None) = 0.95^{39}[/tex]

[tex]P(None) = 0.1352[/tex]

The probability that there is one defect out of the 39 selected tablets is:

[tex]P(One) = 39 * 0.05 * 0.95^{38}[/tex]

[tex]P(One) = 0.2777[/tex]

Add both probabilities

[tex]P(Accepted) = 0.1352 + 0.2777[/tex]

[tex]P(Accepted) = 0.4129[/tex]

Hence, the probability that a shipment will be accepted is 0.4129

The above probability is less than 0.5.

This means that many shipments will be rejected

This makes it similar by the corresponding angles converse theorem.

Definition of converse

the reverse of another

The corresponding angles theorem is for the congruency of the angles by parallel lines. Here we want to see if the lines are parallel given the congruency of the angles.

We can flip the operation, checking to see if the angles are congruent, which proves that the lines are parallel.

a car park charges 1.50 to each car entering. the car park only accepts £1 coins and 50p coins. here are the coins collected on a particular day. number of £1 coins: 172 number of 50p coins:256 making the assumption that all drivers paid the exact amount due on that day, work out the percentage of drivers that paid with three 50p coins​

Answers

Subtract the amount of £1 coins from 50p coins:


256-172 = 84

84/3 coins = 28 people paid with 3 coins.


172 people paid using £1 coins

The longer leg of a right triangle is 4 inches longer than the shorter leg. The hypotenuse is 8 inches longer than the shorter leg. Find the side lengths of the
triangle.

Answers

Answer:

lengths are 12, 16, and 20

Step-by-step explanation:

let 's' = length of smaller leg

let '4+s' = length of second leg

let '8+s' = length of hypotenuse

Now use the Pythagorean Theorem:  a² + b² = c²

s² + (4+s)² = (8+s)²

s² + 16 + 8s + s² = 64 + 16s + s²

2s² + 8s + 16 = 64 + 16s + s²

subtract s² from each side:

s² + 8s + 16 = 64 + 16s

subtract '16s' from each side:

s² - 8s + 16 = 64

subtract 64 from each side:

s² -8s - 48 = 0

factor:

(s+4)(s-12) = 0

's equals -4 and 12 but -4 is discarded as a length so smallest side is 12
