What's the range of f(x)=x+6 if x ∈(-4,-1)

Answers

Answer:

the range of is (2 , 5)

Step-by-step explanation:

f(x)=x+6

f is an increasing function then the range of is

f(-4,-1) = (f(-4) , f(-1))

f(-4) = -4 + 6 = 2

f(-1) = -1 + 6 = 5

Therefore

the range of is f(-4,-1) = (2 , 5)

What is the value of RS?

Answers

Answer:

RS = 16

Step-by-step explanation:

If a line is parallel to a side of a triangle and intersects the other 2 sides , it divides those sides proportionally.

PR is such a line , then

[tex]\frac{QR}{RS}[/tex] = [tex]\frac{QP}{PT}[/tex] ( substitute values )

[tex]\frac{32}{RS}[/tex] = [tex]\frac{42}{21}[/tex] = 2 ( multiply both sides by RS )

A vending machine that takes only dimes and
quarters contains 30 coins, with a total value of
$4.20. How many of each coin are there?

Answers

Answer: 22 dimes, 8 quarters
Explanation: You can guess and check. You know you need more dimes because they are worth less. It would take more dimes to make up 30 coins. And you also know that quarters cannot make .20 exactly. So your number of dimes must make .20. So I guessed numbers that would have .20 left over, and added quarters to get to $4.20.

Select the equation of the line that passes through the point (2, –1) and has slope 3 in point-slope form.

(y + 1) = 3(x – 2)

(y – 1) = 3(x + 2)

(x + 2) = 3(y – 1)

(x – 2) = 3(y + 1)

Answers

Answer:

(y + 1) = 3( x +2)

Step-by-step explanation:

from equation,

y - y1 = m( x - x1)

given x1=2, y1= -1

m = 3 (slope)

substitute

y - (-1) = 3( x - 2)

ans: y+1= 3(x+2)

A notebook costs £1.60, a pen costs 37p, a pencil costs 21p and a sharpener costs 86p.
Remi buys 3 pencils, 2 pens, 3 sharpeners and some notebooks.
He pays with £8 and receives 85p change.
How many notebooks did he buy?
notebooks

Answers

£1.60 each notebooks
3 pencils times 21p= 63p
2pens times 37p=74p
3sharpeners times 86p=258p
63p+74p+258p=£3.95
£8-3.95=£4.05
£4.05-£1.60= £2.45
£2.45-£1.60=85p
So… he bought 2 notebooks

Answer:

Step-by-step explanation:

£1 = 100p

3*21p+2*37p+3*86p+x*160p (x is the number of notebooks)

63p+74p+258p+x*160p = 395p+x*160p

He paid £8 so he paid 800p

800p-395p = 405p

405p-85p = 320p

320p:160p = 2

He bought 2 notebooks

Find the area of the sector of the circle.

A)40π
B)200π
C)60π
D)300π

Answers

Answer:

the answer is D) 300 π

Step-by-step explanation:

Formula for Area of sector is:

θ/360° * π * (r)^2

here,

θ= 30° and radius= 60 in

so, after we substitute, we get:

30/360* π* 60*60 after simplifying we get:

= 1/12* π* 5*60

=300π

What is an equation?

An equation is an expression used to show the relationship between two or more numbers and variables.

Area of P = 40 * x = 40x cm²

Area of Q = y * (1.25 * 40) = 50y cm²

Given that area of Q = 90% if P = 0.9(40x) = 36x cm²

50y cm² = 36x cm²

6. A rectangle with a length of 15 feet has a
diagonal that measures 17 feet. Find the
perimeter of the rectangle.

Answers

Answer:

46 feet

Step-by-step explanation:

it is a 8-15-17 Pythagorean Triple (or you can use the Pythagorean theorem)

P=8+8+15+15=46

The perimeter of the rectangle with a length of 15 feet and has a diagonal that measures 17 feet is: A. 46 feet.

What is the Perimeter of a Rectangle?

To find the perimeter of the rectangle, we need to know the width of the rectangle. Let's call the width of the rectangle W.

In a rectangle, the diagonal, length, and width are related by the Pythagorean theorem:

Diagonal² = Length² + Width²

In this case, the diagonal (D) is 17 feet, and the length (L) is 15 feet. So we have:

17² = 15² + W²

289 = 225 + W²

Now, let's solve for W:

W² = 289 - 225

W² = 64

W = √64

W = 8 feet

Now that we know the width is 8 feet, we can calculate the perimeter (P) of the rectangle:

Perimeter = 2 * (Length + Width)

= 2 * (15 + 8)

= 2 * 23

Perimeter = 46 feet

The tank of a car holds 10 gallons of gas.
How many liters does the tank hold? Round to the nearest tenth.

Answers

Answer:

37.9 liters

Step-by-step explanation:

Multiply the number of gallons by 3.785 to convert to liters

Multiplying by ten moves the decimal point over to the right

3.785 * 10 = 37.85

The tenths place is where the 8 is, and since 5 is [tex]\geq[/tex] (greater than or equal to) 5 that makes the 8 round up to a 9

resulting in...

Answers

Answer:

The median is 69.5

Step-by-step explanation:

The median is also known as the middle value. To find the median, you first arrange your data in numerical order.

Numerical order:

50, 50, 53, 55, 55, 57, 62, 63, 64, 64, 65, 68, 68, 69, 69, 70, 71, 71, 71, 72, 72, 73, 75, 75, 75, 77, 77, 78, 79, 80

There are 30 numbers, which means that the median is between the 15th and 16th value (69 and 70).

69 + 70 = 139

139/2 = 69.5

Therefore, the median of this data set is 69.5

Step-by-step explanation:

Split the shape evenly so 11 x 14 and 9 x 9then multly and add

when slpitting up the number some times you have to add or subtract so to get 9 x 9 we just take 20 then take away 11 due to the line going through 20 and 20 - 11 = 9

9 x 9 = 81

11 x 14 = 154

81 + 154 = 235

Simular to the first one but the cutting line is different. this time the line cuts through 14

9 x 20 = 180

11 x 5 = 55

180 + 55 = 235
