What is the area of this figure?

Answer:

y^60

Step-by-step explanation:

(a^b)^b= a ^ b times b

12 times 5 is 60 so it's y^60

sorry my explaination is so complicated but im confident in the answer

Answer:

5.6

Step-by-step explanation:

First we need to figure out how to get from 10 to 14. If we multiply 10 by 1.4, we get 14. Multiply 4 by 1.4 as well to get 5.6 for x.

I think the answer is 18.2 cm

Step-by-step explanation:

Since angles opposite congruent sides in a triangle are congruent, w=67.

Now, since the sum of the measures of the interior angles of a triangle is 180 degrees, x=180-67-67=46

Ok. First, let's find the slope using the slope formula.

[tex]m = \frac{y2-y1}{x2-x1} =\frac{9-5}{2-2} = 4/0[/tex]

4/0 is undefined.

When the slope is undefined, that means that it's a straight line going down from the x.

So the equation is just x = 2

Answer:

C: y + 3 = 1/4(x + 4)

Step-by-step explanation:

Perpendicular to a given line means opposite inverse of the slope...

Equation of line is: y = -4x - 3

slope in above equation is -4, perpendicular would be 1/4

Perpendicular equation of a line through P(-4, -3):

y = mx + b

-3 = 1/4(-4) + b

-3 = -1 + b

b = -2

Use perpendicular slope and the b from above to form the perpendicular equation of line:

y = 1/4x - 2

Check:

(-3) = 1/4(-4) - 2

-3 = -1 - 2

-3 = -3

Answer:

  B.  18 cm²

Step-by-step explanation:

The area of a trapezoid can be found using the formula ...

  A = 1/2(b1 +b2)h

For the given dimensions, the area is ...

  A = 1/2(7 cm +5 cm)(3 cm) = 1/2(12)(3) cm² = 18 cm²

Answer:

Part 1

Multiply both sides by 2π

2πf = √(g/L)

Square both sides

4π²f²= g/L

Invert both sides

1/(4π²f²) = L/g

Multiply both side by g

g/(4π²f²) = L

We usually write an equation with the subject (L) n the left

L = g/(4π²f²)

________________________

Part 2

Using the above equation with the given values:

L = g/(4π²f²)

. .= 9.8 / (4π² x 1.6²)

. .= 0.097m (= 9.7cm)

________________________

By the way, where it says

“f=1.6 then there are 2 beats a second, or 192 beats per minute (bpm).”

this should say

“f=1.6 then there are 3.2 beats a second, or 192 beats per minute (bpm)”

Step-by-step explanation:

The values are L = g/(4π²f²) and L.= 0.097m (= 9.7cm)

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

Here, we have,

Part 1

Multiply both sides by 2π

2πf = √(g/L)

Square both sides

4π²f²= g/L

Invert both sides

1/(4π²f²) = L/g

Multiply both side by g

g/(4π²f²) = L

We usually write an equation with the subject (L) n the left

L = g/(4π²f²)

________________________

Part 2

Using the above equation with the given values:

L = g/(4π²f²)

L.= 9.8 / (4π² x 1.6²)

L.= 0.097m (= 9.7cm)

Hence, The values are L = g/(4π²f²) and L.= 0.097m (= 9.7cm).

Answer:

y= 3x - 5

Step-by-step explanation:

coordinates given: (4,7) & (1, -2)

to find m (slope) = rise/run = (y2-y1) /(x2-x1)

= ( -2-7) / (1 - 4)

= -9/-3

= 3

therefore, y=3x + b

to find b:

taken coordinate: (4,7)

y=3x + b

7=3 (4) + b

7= 12 + b

7-12 = b

-5 = b

(*the value of b will be same even if we take the other coordinate)

therefore, y = 3x -5

Answer:

Step-by-step explanation:

A black bar with 7 copper colored coils around it is the strongest.

Electromagnets are defined as magnet which works through electricity.

We know permanent magnets show magnetic properties every time. We cannot alter it. But electromagnets only acts as a magnet when current passes through it. Otherwise, it is just a coiled wire.

Strength of electromagnet depends on basically two things:

First, the amount of current flowing through the wire and

Second, the number of turns of wire around the coil.

Here there are four electromagnets which are black bar with 5, 2, 7 and 4 copper colored coils around it.

Number of coils is maximum for the black bar with 7 copper colored coils around it, which results in the strongest electromagnet.

Hence, a black bar having 7 copper colored coils around it is the strongest.

Step-by-step explanation:

Answer:

s=144

t=36

Step-by-step explanation:

you minus 180 from 36 and you get 144 for s

then you minus 180 from 144 to get t

Answer:

t = 36°

s = 108°

Step-by-step explanation:

FE and DE are congruent. This means that triangle ΔDEF is isosceles.

Base angles (∠EFD and ∠EDF) in isosceles triangles are congurent.

∠EFD is 36°. This means that ∠t is also 36°

The measure of all the angles in a triangle is 180°

[tex]36+36+x=180\\72+x=180\\x=108[/tex]

∠s = 108°
