The verticle angles are AB and ED

Step-by-step explanation:

Answer:

Step-by-step explanation:

take 74 degree as reference angle

using cos rule

cos 74 =adjacent/hypotenuse

0.275=x/12

12*0.275=x

3.3=x

take 36 degree as reference angle

using sin rule

sin 36=opposite/hypotenuse

0.587=x/11

0.587*11=x

6.457=x

6.5=x

take 39 degree as reference angle

using tan rule

tan 39=opposite/adjacent

0.809=13/x

x=13/0.809

x=16.06

x=16.1

take 16 degree as reference angle

using tan rule

tan 16=opposite /adjacent

0.286=x/14

0.286*14=x

4.00=x

4.0=x

x=

Answer:

m<8 = 46°

Step-by-step explanation:

m<2 = m7 (alternate exterior angles are congruent)

Substitute

3x + 53 = 7x - 55

Collect like terms

3x - 7x = -53 - 55

-4x = -108

Divide both sides by -4

-4x/-4 = -108/-4

x = 27

m<8 + m<7 = 180° (linear pair angles)

Substitute

m<8 + 7x - 55 = 180°

Plug in the value of x

m<8 + 7(27) - 55 = 180

m<8 + 189 - 55 = 180

m<8 + 134 = 180

Subtract 134 from each side

m<8 = 180 - 134

m<8 = 46°

Answer:

Step-by-step explanation:

3,-3

Answer:

subtract 4 from both sides

Step-by-step explanation:

Given

x² + 2x - 11 = 4

First step : subtract 4 from both sides

x² + 2x - 15 = 0 ← in standard form

Second step : factorise the quadratic

(x + 5)(x - 3) = 0 ← in factored form

Third step : equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x - 3 = 0 ⇒ x = 3

Fourth step : state the solutions

solutions are x = - 5, x = 3

Answer:

If we are solving x + 5< 6 the inequality is x< 1

Given:

Initial value = 400

Interest rate = 5% compounded quarterly.

To find:

The function that gives you the amount of money in dollars, J(t) in t years after the initial deposit.

Solution:

The formula for amount is:

[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]

Where, P is principal, r is the rate of interest in decimals, n is the number of times interest compounded in an year and t is the number of years.

The interest rate is 5% compounded quarterly. So, r=0.05 and n=4.

Substituting [tex]P=400,\ r=0.05,\ n=4[/tex] in the above formula, we get

[tex]A=400\left(1+\dfrac{0.05}{4}\right)^{4t}[/tex]

[tex]A=400\left(1+0.0125\right)^{4t}[/tex]

[tex]A=400\left(1.0125\right)^{4t}[/tex]

The required function notation is:

[tex]J(t)=400\left(1.0125\right)^{4t}[/tex]

Therefore, the amount of money in dollars, J(t) in t years after the initial deposit is [tex]J(t)=400\left(1.0125\right)^{4t}[/tex].

Answer:

Step-by-step explanation:

I'm going to  assume you meant y = ab^x. If this is not correct, leave a comment.

x = 0

y = 7

7 = a * b^0

anything to the zero power is 1

y = a*b^0

y = a*1

7 = a

So far what you have is

y = 7 * b^x

Now let

x = 9

y = 3584  

3584 = 7 * b^9         Divide by 7

3584/7 = b^9

512 = b^9

If you knew how to use logs, that would be the surest way to do this question. However I'm going to make an assumption again and assume that you have not taken those yet.

So the easiest way is to find out what raised to the 9th power will equal 512

Could b = 5?

5^9 = 1 million 9 hundred thousand something. 5 is far too big. Make sure you understand why. 1 million is far greater than 512

So let's try b = 3

3^9 = 19 thousand which is still far too big. 19 thousand something is far larger than 512.

We have just one more number that we can try.

2^9 = 512 and we have it

Answer y = 7*2^x

Answer:

The number of the sequence are 2, 3, 6, 15

The difference between 2 and 3 is 1 i.e. 30.

The difference between 3 and 6 is 3 i.e. 31.

The difference between 6 and 15 is 9 i.e. 32.

Let the next number in the given sequence be some natural number x.

Now, following the pattern, the difference between 15 and x has to be equal to 33=27.

i.e.

x−15=27⟹x=27+15=42

Hence

The next number in the sequence is 42.

Answer:

Length: 12 cm

Width: 8 cm

Height; 7 cm

Step-by-step explanation:

We are told that the areas of 2 of the faces are 84cm² and 56cm².

Now, the side faces are 4 in total with 2 each having same areas.

Thus, it means they would have the same height.

Let's find the highest common factor between 84cm² and 56cm².

The highest number that can be divide each equally is 7.

Thus;

12 × 7 = 84 cm²

8 × 7 = 56 cm²

This means, the bottom part will measure 12 cm by 8 cm.

Thus, the complete measurement is;

Length: 12 cm

Width: 8 cm

Height; 7 cm

Let's check if it will give us a Volume equal to that given.

Thus;

Volume = 12 × 8 × 7 = 672 cm²

This is same as that given and so our dimensions are correct.

Answer:

337+x+89y+210xy

Step-by-step explanation:

x-2+(5y*7*6x)+89y-6+345

x-2+(210xy)+89y-6+345

x-2+210xy+89y-6+345

-2-6+345+x+89y+210xy

337+x+89y+210xy

Answer:

X = 19

Step-by-step explanation:

Two parallel lines cut by a transversal means the corresponding angles are congruent. Set each equation equal to each other and solve for x.

2x+78= 7x-17

Add 17 to both sides: 2x + 95= 7x

Then subtract 2x from both sides: 95= 5x

divide each side by 5, for final answer: x= 19

Answer:

angle 3 is 87 degree

Step-by-step explanation:

-7x+191=-5x+163(they are alternte interior angle)

-7x+5x=163-191

-2x=-28

x=-28/-2

x=14

substitute the value of x in -5x+163

-5*14+163

-70+163

93

Now,

angle 3 + (-5x+163) = 180 degree (they are cointerior angles)

angle 3 + 93 = 180

angle 3 = 180-93

angle 3 = 87 degree

Answer:

y = -1/3x + 7/3

Step-by-step explanation:

A line that is perpendicular to another line has the opposite reciprocal slope. That means we flip the slope of the original line and place a negative in front. Since the original slope is 3, the slope perpendicular is -1/3.

Now that we know the slope, and because they gave us a point on that line, we can create a line. Plug in the points and the slope into y = mx + b, to solve for b, the y-intercept.

3 = -1/3 (-2) + b

9/3 = 2/3 + b

7/3 = b

Now we can create a line in slope intercept form: y = -1/3x + 7/3

Here is Standard Form if needed: x + 3y = 7

Answer:

-2 < x < ఔ

Step-by-step explanation:

F’x = 3x^2 + 18x + 24

F’x = 3(x^2 +6x +8)

F’x = 3(x+4)(x+2)

One of the points of inflection will be at x = -2, and after -2 we know the equation will increase because it is positive
