Step-by-step explanation:

If the hypotenuse of PQR triangle is 5 and perpendicular is [tex]\sqrt{2}[/tex],then value of sin²R is 2/25.

Given that the hypotenuse is 5 and perpendicular is [tex]\sqrt{2}[/tex].

We are required to find the value of sin²R.

Trigonometric ratios are basically the ratios of the sides of the right angled triangle.

Sin is the ratio of perpendicular and hypotenuse of the right angled triangle. We can easily find the value of sin²R with the help of ratio of perpendicular and hypotenuse.

sin R=PQ/PR

sin R=[tex]\sqrt{2}[/tex]/5

Squaring both sides,

sin² R=[tex](\sqrt{2} )^{2}[/tex]/[tex](5)^{2}[/tex]

sin²R=2/25

Hence if the hypotenuse is 5 and perpendicular is [tex]\sqrt{2}[/tex],then value of sin²R is 2/25.

Two methods...

How can we divide easily by 5?

We know

Then

The common method

Answer:

8 1/3

Step-by-step explanation:

4 1/2 + 3 5/6

First, we must convert the fraction to a common denominator.

1/2 = 3/6

4 3/6 + 3 5/6

3/6 + 5/6 = 8/6 = 1 2/6 = 1 1/3

1 1/3 + 4 + 3 = 8 1/3

The answer is 8 1/3.

Answer: 8 1/3

Step-by-step explanation:

4 1/2 + 3 5/6

So what we do is we make them have the same denominator

1/2 = 3/6

Now... 3/6 + 5/6 = 8/6

8/6 will have to be converted into a mixed number so...

that will be 1 2/6

now we add the two whole numbers 4 and 3 which is 7

7+1=8

8 + 2/6 = 8 2/6

now simplify that and you get 8 1/3

a) If function be [tex]$f(x)=\frac{x^2+(17-4 x)}{9 x}$[/tex] then the value of f(5) = 22/45.

b) If function be g(x) = 3 x² - 6x + 9 then the value of g(x + 3) = 3x² + 12x + 18.

c)  If the function be [tex]$h(y)=\frac{y^3-5}{7 y}$[/tex] then the value of [tex]$h(2x) =\frac{8 x^3-5}{14 x}$$[/tex].

a) Let the function be [tex]$f(x)=\frac{x^2+(17-4 x)}{9 x}$[/tex]

substitute the value of x = 5, then

[tex]$f(5) = \frac{5^2+(17-4 \cdot 5)}{9 \cdot 5}$$[/tex]

simplifying the above equation, we get

[tex]$=\frac{22}{45}$$[/tex]

Therefore, the correct answer is 22/45.

b) Let the function be g(x) = 3 x² - 6x + 9

substitute the value of g(x) = g(x + 3), then we get

To estimate the value of g(x + 3) = 3(x + 3)² - 6(x + 3) + 9

= 3x² + 18x + 27 - 6(x + 3) + 9

simplifying the above equation, we get

=3x² + 18x + 27 - 6x - 18 + 9

Group like terms, we get

= 3x² + 18x - 6x + 27 - 18 + 9

=3x² + 12x + 27 - 18 + 9

= 3x² + 12x + 18

Therefore, the value of g(x + 3) = 3x² + 12x + 18.

b) Let the function be [tex]$h(y)=\frac{y^3-5}{7 y}$[/tex]

substitute the value of y = 2x, then we get

[tex]$h(2x)=\frac{(2x)^3-5}{7 (2x)}$[/tex]

simplifying the above equation, we get

[tex]$=\frac{8 x^3-5}{7 \cdot 2 x}$$[/tex]

[tex]$=\frac{8 x^3-5}{14 x}$$[/tex]

Therefore, the value of [tex]$h(2x) =\frac{8 x^3-5}{14 x}$$[/tex].

Using Pythagoras's theorem we can calculate that the bucket must reach57.134 feet .

We know from the Pythagoras theorem of aright angled triangle , the sum of squares of the two legs of a right triangle is equal to the square of the hypotenuse of the same triangle.

From the question we can ascertain that the height at which the cat is stuck is 40.4 feet.

Now it is given that the rescue ladder came in at 45 ° . So the length of the legs are equal.

Therefore length of ladder which is the hypotenuse = √(2×40.4²)

Length = 57.134... feet

length ≈ 57.13 feet

Therefore the bucket must reach 57.13 feet which is the height at which the cat is stuck on the tree of length 40.4 feet.

Given the angles in the trapezoid:

• 36 degrees

• 113 degrees

Let's find the values of a and b.

In a trapezoid, the angles on the same side of one transversal are supplementary angles and supplementary angles sum up to 180 degrees.

Hence, we have:

a° + 36° = 180°

b° + 113 = 180°

Now, let's solve for a and b.

a° + 36° = 180°

Subtract 36° from both sides:

a° + 36° - 36° = 180 - 36°

a° = 144°

b° + 113° = 180°

Subtract 113 from both sides:

b° + 113° - 113° = 180° - 113°

b = 67°

The probability of best simulations to choose one pair of shoes from two and one pair of socks from six can be to flip a coin and roll a die, respectively.

The total number of shoe pairs = 2

The number of pairs that need to be chosen from the total = 1

That is, the probability of choosing one pair out of 2 = 1 ÷ 2 = 0.5

The best simulation for 0.5 probability is flipping a coin, as it has the same probability ratio and has 2 sides to choose from.

The total number of sock pairs = 6

The number of pairs that need to be chosen from the total = is 6

That is, the probability of choosing one pair out of 6 = 1 ÷ 6

The best simulation for 1 ÷ 6 probability is rolling a die, as it has the same probability ratio and has 6 sides to choose from.

Hello, the detailed answer is given below. Good luck!

Any exponential function will contain a horizontal asymptote of y = 0.

Therefore, the correct answer is as follows:

A horizontal asymptote is a line that runs along the x-axis of a function graph but is not actually a part of the graph itself. "far" right or left, depending on your preference. Eventually, whether it is large enough or little, the graph may cross it.

The initial value of this function exists as the y-intercept, marked as (0, 5). The label on the graph tells you this exists the snake population in year 0.

We note that the snake population goes up by a factor of 2 for each increase of 1 in the number of years. This means the function exists as an exponential function with a base of 2.

The consecutive even numbers are 12 and 14.

Even numbers can be divided into two equal groups or pairs and are exactly divisible by two. For instance, 2, 4, 6, 8, and so on. These numbers can be divided into equal groups. Consecutive numbers are numbers that follow each other in descending order from smallest to greatest. Consecutive even numbers are even integers that are separated by a factor of two.

Let the consecutive even numbers be x and x+2.

The sum of the numbers is 340. This will be illustrated as:

x² + (x + 2)² = 340

x² + (x + 2)(x + 2) = 340

x² + x² + 4x + 4 = 340

Collect like terms

2x² + 4x + 4 - 340 = 0.

2x² + 4x - 336 = 0

Divide through by 2

x² + 2x - 168 = 0

x² - 14x + 12x -168 = 0

x(x - 14) + 12(x - 14) = 0.

(x + 12)(x - 14) = 0

This shows that the numbers are 12 and 14

Check: 12² + 14² = 144 + 196 = 340.

The function in option number C is a linear function.

Here, we are given 4 functions. Let us check them one by one to see if they are linear or not-

A. In this function, if x = 0, y =11

if x = 1, y = 7

Thus, if x increases by 1, y increases by 4.

but now if we see when x = 2, y = 5 which is not an increase of 4.

Thus, the given function is not linear.

B. In this function, if x = 0, y = 0

if x = 1, y = 0

Thus, if x increases by 1, y increases by 0.

but now if we see when x = 2, y = -1 which is not an increase of 0.

Thus, the given function is not linear.

C. In this function, if x = 0, y = 6

if x = 1, y = 12

Thus, if x increases by 1, y increases by 6.

when x = 2, y = 18 which is an increase of 6.

similarly, when x = 3, y = 24 which is an increase of 6.

Thus, the given function is linear.

Step-by-step explanation:

1275 spaces are in the parking garage.

What is linear addition?
The phrase "the addition" refers to combining two or more numbers. Adding two numbers is indicated by the plus sign (+), therefore adding three is written as three plus three. Two whole numbers added together result in another whole number. Two natural numbers added together will provide the original natural number once again. Two integers added together will result in an integer; two positive integers added together will result in a positive integer; two negative integers added together will result in a negative number; and one positive and one negative integer added together will result in an integer with the same sign as the largest number.

Given, total number of cars parked in garage = 551
Empty spaces available in first floor = 128
Empty spaces available in second floor = 294
Empty spaces available in third floor = 302
Therefore, total spaces in the parking garage = 551 + 128 + 294 + 302
= 1275
Thus, 1275 spaces are in the parking garage.
