Answer 1
(3x+2)+(4x+1)+(2x+1)=180
9x+4=180
9x = 45
X= 5
Answer 2

Answer:

Step-by-step explanation:

if you add all the angles in a triangle together, its 180 degrees.

so, (3x+2)+(4x+1)+(2x+1) = 180

we can combine like terms so 9x+4=180

                                                    9x=176

                                                       x=19.6 degrees

now plug the x into each angle and that's them

n = -21.1/2

Step-by-step explanation:

[tex]56 = 2n + 99[/tex]

Collect like terms and simplify

[tex]56 - 99 = 2n \\ - 43 = 2n[/tex]

Divide both sides of the equation by 2

[tex] \frac{ - 43}{2} = \frac{2n}{2} [/tex]

Simplify

[tex]n = - \frac{43}{2} = - 21 \frac{1}{2} [/tex]

Answers

Answer and Step-by-step explanation:

44, 6, and 24 do not have perfect squares.

To be a perfect square, they have to be able to have a number that, when it multiplies itself by itself (needs to be a whole number), it turns into the bigger number.

44, 6, and 24 can't do this when being square rooted.

16 turns into 4.

81 turns into 9.

49 turns into 7.

Write an equation for the circle

Answers

Given:

The graph of a circle.

To find:

The equation of the given circle.

Solution:

The standard form of a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]          ...(i)

Where, (h,k) is vertex and r is the radius.

From the given graph it is clear that the radius of the circle is 4 units and the center of the circle is (-2,2).

Putting [tex]h=-2, k=2[/tex] and [tex]r=4[/tex] in (i), we get

[tex](x-(-2))^2+(y-(2))^2=(4)^2[/tex]

[tex](x+2)^2+(y-2)^2=16[/tex]

Therefore, the equation of the circle is [tex](x+2)^2+(y-2)^2=16[/tex].

Mackenzie invested $770 in an account paying an interest rate of 6.1% compounded
continuously. Assuming no deposits or withdrawals are made, how long would it
take, to the nearest year, for the value of the account to reach $1,830?

Answers

Answer:

14

Step-by-step explanation:

The value of the account will reach to $1,830 in 15 years.

What is compound interest?

Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.

Given that, Mackenzie invested $770 in an account paying an interest rate of 6.1% compounded continuously after a certain period of time the mount becomes $1830

We know that,

[tex]A = P(1+r)^n[/tex]

Where, A = amount, P = principal, r = rate and n = time.

1830 = 770(1+0.061)ⁿ

1830 / 770 = (1.061)ⁿ

2.37 =  (1.061)ⁿ

Taking log both side,

log(2.37) = n log(1.061)

n = log(2.37) / log(1.061)

n = 14.57 ≈ 15

Hence, the value of the account will reach to $1,830 in 15 years.

In a right triangle, one acute angle is 22º and the hypotenuse is 70 cm. Find the
lengths of the legs and the other angle measure.

Answers

Answer:

Adjacent leg (In relation to the angle that is measure 22 degrees)= 70*Cosine 22 or 64.9; Opposite leg (In relation to the angle that is measure 22 degrees)=70* Sin 22 or 26.22

Step-by-step explanation:

The other angle measure is 90-22 or 68.

To find the length of the adjacent leg (a) use cosine. Remember cosine is Adjacent leg over hypotenuse.

Cosine 22= a/70- Multiply by 70

70* Cosine 22=a or about 64.9

To find the length of the opposite leg (o) use sine. Remember sine is Opposite leg over hypotenuse

Sine 22= o/70

70*Sine 22=o

o= about 26.22

.12m = 78 + .09m
how do you solve this?!

Answers

Answer:

m = 2600

Step-by-step explanation:

0.12m = 78 + 0.09m

0.12m - 0.09m = 78 + 0.09m - 0.09m

0.03m = 78

m = 2600

Make sure to double check!

2600 x 0.12 = 78 + 0.09 x 2600

312 = 78 + 234

312 = 312

Answer:

(Assuming the . means its a decimal...)

Step-by-step explanation:

Rewrite equation

0.12m = 78 + 0.09m

Multiply each side by 100

12m=7800 + 9m

Subtract 9m on both sides

12m-9m=7800+9m-9m

3m=7800

Divide both sides by 3

m = 2600

We move all terms to the left:

15/3-(45/x)=0

Domain of the equation: x)!=0

x!=0/1

x∈R

We add all the numbers together, and all the variables

-(+45/x)+15/3=0

We add all the numbers together, and all the variables

-(+45/x)+5=0

We get rid of parentheses

-45/x+5=0

We multiply all the terms by the denominator

5*x-45=0

We add all the numbers together, and all the variables

5x-45=0

We move all terms containing x to the left, all other terms to the right

Consider function f. F(x) = ^3square8x + 4

Answers

Answer:

[tex]f^{-1}(x)=\frac{1}{8}(x-4)^{3}[/tex]

Step-by-step explanation:

Given function is,

f(x) = [tex]\sqrt[3]{8x}+4[/tex]

To find the inverse of this function,

Rewrite the function as a equation,

y = [tex]\sqrt[3]{8x}+4[/tex]

Interchange x by y and y by x,

x = [tex]\sqrt[3]{8y}+4[/tex]

Now solve this equation for y,

x - 4 = [tex]\sqrt[3]{8y}[/tex]

(x - 4)³ = [tex](\sqrt[3]{8y})^3[/tex]

(x - 4)³ = 8y

y = [tex]\frac{1}{8}(x-4)^{3}[/tex]

Now convert the equation into function,

[tex]f^{-1}(x)=\frac{1}{8}(x-4)^{3}[/tex]

Triangle Congruency please help!!

Answers

Answer:

A

Step-by-step explanation:

the nice thing about triangle is that the smallest angle is always opposite the smallest side, etc. also, we can get the remaining angle because we have 2 angles already and there are always 180 degrees in a triangle.

50+ 63= 113

180-113 =67

so, 50 is the smallest angle and thus the side opposite of it is the smallest. next is side bc because 63 is the next biggest angle measure. lastly, side ac is the largest because it's opposite of the largest angle measure

f(x) = x ^ 2 What is g(x)? ​

Answers

Answer:

A ; g(x) = (1/2 x)^2

Step-by-step explanation:

Here, we want to get g(x)

we have a point on the curve g(x)

The point is represented by (2,1)

What this mean here is that, when x = 2, y = 1

Looking at the first option;

Substitute 1 for y and 2 for x

1 = (1/2 * 2)^2

1 = 1

This means this is our answer

The equation for g(x) is;

g(x) = (1/2 x)^2

Find the equation of a line that passes through (2,9) and is parallel to the graph of y = 3x + 6. Write the equation in slope-intercept form, if possible.

Answers

Answer:

y = 3x + 3

Step-by-step explanation:

If two lines are parallel to each other, they have the same slope.

The first line is y = 3x + 6. Its slope is 3. A line parallel to this one will also have a slope of 3.

Plug this value (3) into your standard point-slope equation of y = mx + b.

y = 3x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (2, 9). Plug in the x and y values into the x and y of the standard equation.

9 = 3(2) + b

To find b, multiply the slope and the input of x (2)

9 = 6 + b

Now, subtract 6 from both sides to isolate b.

3 = b

Plug this into your standard equation.

y = 3x + 3

This equation is parallel to your given equation (y = 3x + 6) and contains point (2, 9)
