Answer:

The true statement is 2(MB) = AB

Step-by-step explanation:

The given figure shows how to bisect a segment

∵ CD is the perpendicular bisector of AB

→ That means CD is perpendicular to AB and intersect it at its mid-point

∴ CD ⊥ AB

∵ CD intersects AB at point M

∴ Point M is the mid-point of AB

∵ M is the mid-point of AB

∴ AM = MB

→ That means each part is half AB

∴ AM = MB = [tex]\frac{1}{2}[/tex] AB

∵ MB = [tex]\frac{1}{2}[/tex] AB

→ Multiply both sides by 2

∴ 2(MB) = AB

∴ The true statement is 2(MB) = AB

Answer:

The answer is below

Step-by-step explanation:

So first to find a prime number, you need to know some multiplication skills.

So prime number is a number that is only divisible by itself or 1.

______

For example

3 is a prime number because it can't be divisible by any number

but

9 is not a prime number, because it can be divisible by 3

3 x 3 = 9

______________________

So you get it now

Now if you get a some number between 1 - 10

you have to use your multiplication skills to see if there are any prime numbers.

_____________________________

so

1  - not a prime number, can't be divisible by any number.

2 - not a prime number, can't be divisible by any number.

3 - not a prime number, can't be divisible by any number

4 - is a prime number, can be divisible a number (2 x 2 = 4)

5 - not a prime number, can't be divisible by any number

6 - is a prime number, can be divisible a number (3 x 2 = 6)

7 - not a prime number, can't be divisible by any number

8 - is a prime number, can be divisible a number (4 x 2 = 8)

9 - is a prime number, can be divisible a number (3 x 3 = 9)

10 - is a prime number, can be divisible a number (5 x 2 = 10)

Answer:

change L.H.S in terms of sin and cos

Step-by-step explanation:

so we know cot x= cos x/sin x. so similarly we have cot y = cos y / sin y. since we have our cot in terms of cosine and sine, get a L.C.M and solve it further.

Answer:

$4.75

Step-by-step explanation:

(had) 8.25 + (deposited) 2.25 = (total) 10.50

10.50 - (withdrew) 5.75 = (total left) 4.75

Answer:

$4.75

Step-by-step explanation:

(Deposit: Add, put in/Withdraw: subtract, take out)

Add $8.25 + $2.25 and you get $10.50. Now subtract that number with $5.75, so $10.50 - $5.75 is a total of $4.75. Mike has $4.75 left in his account.

Answer:

Proof below

Step-by-step explanation:

Trigonometric Identities

We'll prove that:

[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\sin A*\cos A[/tex]

Recall:

[tex]\displaystyle \sec A =\frac{1}{\cos A}[/tex]

[tex]\displaystyle \csc A =\frac{1}{\sin A}[/tex]

Applying those definitions:

[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\frac{\sin A+\cos A}{\frac{1}{\cos A}+\frac{1}{\sin A}}[/tex]

Adding the fractions:

[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\frac{\sin A+\cos A}{\frac{\sin A+\cos A}{\cos A*\sin A}}[/tex]

Dividing the fractions:

[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=(\sin A+\cos A)*\frac{\cos A*\sin A}{\sin A+\cos A}[/tex]

Simplifying:

[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\cos A*\sin A[/tex]

Hence proved

Answer:

For -4, the arrow from zero goes 4 points to the left. Add two more.

Step-by-step explanation:

Answer:

-4 + 2  = -2      and -4 + (-2) = -6

Step-by-step explanation:

-4 + 2  = -2  

On the number line,start at zero

Do 4 jumps to the left (you are at -4)

Then do 2 jumps to the right You are at -2

-4 + (-2) = -6

On the number line,start at zero

Do 4 jumps to the left (you are at -4)

Then do 2 more jumps to the left You are at -6

Answer:

50 hours

Step-by-step explanation:

Given that :

Painter can paint 2 small rooms and a balcony on 50 hours

Small room takes twice as long to paint as a balcony

Let :

Time taken to paint balcony = t

Time taken to paint small room = 2t

t + 2(2t) = 50

t + 4t = 50

5t = 50

t = 10

how long will it take him to paint 1 small room plus 3 balconies?

1 small room = 2t

3 balconies = 3t

2t + 3t = 5t

5(10) = 50 hours

Answer:

6z - 6

Step-by-step explanation:

When you expand you are removing brackets. This means you multiply the outer number by the ones inside thus:

2(3z-3)

2 times 3z is 6z .

2 times 3 is 6.

So the answer is 6z - 6.

Answer:

The volume of the wood used is [tex]1,116\ cm^3[/tex]

Step-by-step explanation:

The Volume of a Rectangular Cuboid

In a rectangular cuboid, all angles are right, and the opposite faces are equal.

The volume of a cuboid of dimensions a,b,c is:

V=a.b.c

The rectangular box is made of wood with externals dimensions of 25 cm by 20 cm by 15 cm.

The external volume of the box is:

[tex]V_e=(25)*(20)*(15)=7,500\ cm^3[/tex]

The walls of the box are 0.5 thick each, this means that the internal dimensions are 1 cm less than the external dimensions, including the lid.

Thus the internal volume is:

[tex]V_i=(24)*(19)*(14)=6,384\ cm^3[/tex]

The volume of the wood used is the difference between the external and the internal volumes:

[tex]V_w=7,500\ cm^3-6,384\ cm^3=1,116\ cm^3[/tex]

The volume of the wood used is [tex]\mathbf{1,116\ cm^3}[/tex]

Step 1: We need to find the slope (or m) FIRST using slope formula*.

[tex]m = \frac{5 - (-1)}{1 - (-1)}\\\\m = \frac{6}{2} = 3[/tex]

m = 3

Step 2: Now we find the y-intercept (or b) using the slope-intercept formula**, ONE of the 2 points given, and the slope we just found.

[tex]5 = 3(1) + b\\\\5 = 3 + b\\\\2 = b[/tex]

b = 2

Step 3: Now we put it all together we get our equation in slope-intercept form**.

[tex]y = 3x + 2[/tex]

**Slope-intercept form: [tex]y = mx + b[/tex]

*Slope formula: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Answer:

Step-by-step explanation:

If we have a linear function and we multiply the input of the function, we aren't really changing the values of the function, we're changing the rate at which those values are reached.

E.g. if you look at the attached picture, we have [tex]f(x) = 2x[/tex] and [tex]f_2(x) = 4x[/tex], which is just [tex]f(2x)[/tex]. The value when the red line is x = 1 is half that of the value of the blue line when x = 1.

The values of the f(2x) line are reaching the values of f(x) twice as fast, meaning it has a slope of twice as much. However, it still grows through the same intercept.

If you're interested in the calculus behind this, look up the chain rule of derivatives.

However, when you start changing the output of the function, you're changing the entire equation. It's not the same line anymore.
