Find the value of y. Geometry, plz only answer if you know how to do it ! thanks

Answer:

39 cm

Step-by-step explanation:

The perimeter of a rectangle is given as 2 (w + l) or 2w + 2l, where w and l are the sides.

Let us use w as 3 cm.

The perimeter of the rectangle is 2(3) + 2l = 6 + 2l

6 + 2l = 84 cm

We move the 6 to the left hand side and it goes from positive to negative.

2l = 84 - 6cm

2l = 78 cm

Divide both sides by 2.

l = 39 cm

There you have the answer for side l.

Hope this helps.

Answer: D is the answer

Step-by-step explanation:

And why are you asking this question? Are you a girl?

Step-by-step explanation:

an equation is a function, if it delivers for every possible input value x exactly one result value y.

b(x) = y = x² + 3

y - 3 = x²

x = sqrt(y -3)

our formally correct

y = sqrt(x - 3)

that is actually NOT a function, as a square root delivers for most x values 2 y values : a positive and a negative value.

d(x) = -9

that means for every possible value of x the result is -9.

reversing this means that the input value of -9 has infinitely many possible results

that is NOT a function.

m(x) = y = -7x

x = -y/7

or formally correct

y = -x/7

that is a normal function. every possible value of x leads to exactly one value of y.

p(x) = y = 1x¹ = x

y = x is its own inverse function.

and this is, of course, a function. every possible value of x leads to exactly one value of y.

Answer:

C

Step-by-step explanation:

The y intercept is where the line first crosses the y axis, so it would be positive 2. The slope is negative because it's diagonally going the left way, and its 3 because from one point to another it's 3 down and 1. The formula for a slope is rise/run, in this case it would be 3/1 which is 3.

Answer:

A) = 5

B) = 3

C) = [tex]2\sqrt{3}[/tex]

D) = 2.2894

Step-by-step explanation:

A)  [tex]x^2=25[/tex]

[tex]\sqrt{x^2} = \sqrt{25} \\x= 5[/tex]

5*5 = 25

B)  [tex]x^3 = 27[/tex]

[tex]\sqrt[3]{x^3} = \sqrt[3]{27} \\x=3[/tex]

3*3*3 = 27

C)  [tex]x^2 = 12\\[/tex]

Answer:

30ab

Step-by-step explanation:

Given expression,

→ 5a × 3 × 2b

Simplifying the expression,

→ 5a × 3 × 2b

→ (5 × 3)a × 2b

→ 15a × 2b

→ (15 × 2)ab

→ 30ab

Hence, the answer is 30ab.

Answer:

perimeter = (8x + 3mm + 5mm) ×2

area = (8x + 3mm) × 5mm

Answer:

Perimeter: 48mm

Area: 95mm

Step-by-step explanation:

Perimeter=2(l+w)

2((8x+3)+5)

-8x=2(3+5)

-8x=2(8)

-8x=16

x=2

2((8(2)+3)+5)= 48

So the perimeter is 48mm

Area=wl

l=19mm

w=5mm

19*5=95mm

So the area is 95mm

Answer:

The value of d is -3.

Step-by-step explanation:

We are given that a line that includes the two points (-8, 9) and (-10, d) have a slope of 6. We want to determine the value of d.

Recall that the formula for slope is:

[tex]\displaystyle m = \frac{\Delta y}{\Delta x}[/tex]

We know that the slope is 6. Substitute:

[tex]\displaystyle (6) = \frac{(d) - (9) }{(-10) - (-8)}[/tex]

Solve for d:

[tex]\displaystyle \begin{aligned} 6 & = \frac{d - 9}{-10 + 8} \\ \\ 6 & = \frac{d - 9}{-2} \\ \\ -12 & = d - 9 \\ \\ d & = -3 \end{aligned}[/tex]

In conclusion, the value of d is -3.

Answer:

6

Step-by-step explanation:

32 = 12 + 4 ( z - 1 )

32 - 12 = 4 ( z - 1 )

20 = 4 ( z - 1 )

20 / 4 = z - 1

5 = z - 1

z - 1 = 5

z = 5 + 1

z = 6

The restriction of the domain of the function will be y = (x - 2)², x ≥ 2. Then the correct option is B.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.

Then the equation of the parabola will be given as,

y = a(x - h)² + k

Then the parabolic function is given below.

y = (x - 2)²

The restriction of the domain will result in the inverse being a function given as,

x - 2 ≥ 0

x ≥ 2

The restriction of the domain of the function will be y = (x - 2)², x ≥ 2. Then the correct option is B.

Answer:

736cm²

Step-by-step explanation:

The surface area of a regular pyramid is equal to:

area of the square base + 1/2ps

where p is the perimeter of the base and

s is the height of the slant line of the pyramid.

In your drawing s = 15cm and the base has four equal lengths of 16cm

So first find the area of the base.  Since this is a square, the area is just the

length x the width or 16cm x 16cm = 256cm²

(p) is the perimeter of the base.  Find this by adding all four side of the bottom square together which is 16cm + 16cm + 16cm + 16cm  or  4 x 16cm which is 64cm.

You already were given (s) which is the height of the slanted side from the base to the pointed top.  The drawing gives you this as 15cm.

So plugging all this into the formula, you get:

Surface Area = Area of Base + 1/2 p s

                      =  256 cm² + [1/2 ( 64cm )(15cm)]

                      =  256 cm²  +  {1/2 ( 960 cm²)]

                      =  256 cm²  +  480 cm²

                      =  736 cm²

And, The equivalent fraction that has a denominator of 32 is,

⇒ 20 / 32

We have to given that,

To simplify fraction 10/16 to lowest terms and equivalent fraction that has a denominator of 32.

We have,

⇒ 10 / 16

⇒ 10 ÷ 2 / 16 ÷ 2

⇒ 5 / 8

Therefore, The lowest terms of fraction are, 5/8

And, Let the numerator of the fraction with denominator 32 is, x

Hence, It can be written as,

⇒ x / 32

Equivalent to 10/16,

⇒ 10/16 = x/32

⇒ 32 x 10 = 16x

⇒ 320 = 16x

⇒ x = 20

Therefore, The equivalent fraction that has a denominator of 32 is,

⇒ 20 / 32

we have to find  the measure in degrees (pi)/4.

now, we know that,

Measure of an Angle in Degrees = 180°        

Measure of an Angle in Radians is:

180° × (π/180°) = π = 3.14 Rad
