Answer:

Arc AB = 110

Step-by-step explanation:

<C = 55 degrees. That's the way the triangle is marked. AB = BC.

The central angle is twice the angle made by the end points of line AB

The central angle = 2*55 = 110

The measure of arc AB equals the central angle which makes arc AB = 110

Answer:

b = 7.14cm

Step-by-step explanation:

For this question, we need to use the pythagorean theorem, since it is a right triangle, and we know two sides. The formula for the Pythagorean theorem is c^2 = a^2 + b^2.

1. a = 5.8cm so a^2 will be 5.8 x 5.8 which is 33.64

2. c = 9.2cm so c^2 will be 9.2 x 9.2 which is 84.64

3. If we add these to our Pythagorean equation, it will be 84.64 = 33.64 + b^2. --> 51 = b^2 --> b = 7.141428....

4. Since we need to round it to two decimal places, b will be 7.14.

Answer:

The range is all real numbers for the inverse

Step-by-step explanation:

f(x) = 2x+1

The domain is all real numbers

The range is all real numbers

For the inverse, the domain becomes the range

The range becomes the domain

The domain is all real numbers

The range is all real numbers

Step-by-step explanation:

Given the function f(x) = 2x + 1

find : the range of the inverse of f(x) = 2x + 1

solutions:

f(x) = 2x + 1

y = 2x + 1

2x = y - 1

x = (y -1)/2

f~¹(x) = (x-1) /2

since the denominator is the constant number, so the range of function is all Real numbers

Answer:

the anserw would be B

Step-by-step explanation:

The relationship that explains the exponential relationship between the year and amount of energy used is: Option B: The amount of energy used decreases by different amount each year.

Rate of an exponential function is  in terms of exponential function itself. It's not constant, and always changing. For example, the rate of [tex]y = e^x[/tex] with respect to x is [tex]y' = e^x[/tex] itself, which increases as x increases.

The given table is:

Year(Serial no.)   Amount of energy used (kWh)

          1                      1,000,000

         2                         900,000

         3                         810,000

         4                         792,000
The differences between each consequent years of the amount of energy used is:

1000000 - 900000 = 100000

900000 - 810000 = 90000

810000 - 792000 = 18000

So, we see that the decrement is done by decreasing amount.

So rate of change wasn't constant but continuosly changing.

Thus, Option C is clearly wrong.

We see that 100,000 is 10% of 1,000,000

and 90,000 is 10% of next years amount 900,000

but 18,000 is not 10% of next years amount which is 810,000

Thus, Option A is wrong too.

Option B is correct in its statement, and so as option D because we don't see any immediate pattern in the decrement, except that the energy is just decreasing, so its unexpected.

The rate of exponentially related variables is not unexpected though.

So, its only Option B which is closest (among other options) to the intention of telling that the relation between the year and the amount of energy used is exponential, although it doesn't prove that the relationship is exponential. (because, suppose the function i take is [tex]y = x^2[/tex], then its rate with respect to x is [tex]y' = 2x[/tex] and this rate is also non-constant, but the function wasn't exponential).

Thus, the relationship that explains the exponential relationship between the year and amount of energy used is: Option B: The amount of energy used decreases by different amount each year.

Answer:

a)     y + 3y + (y - 2) + 4(y - 2) = 116

b)     y = 14

c)     48

Step-by-step explanation:

Sasha says. I am y years old.       y

mother's age is 3 times my age     3y

brother is 2 years younger than me      y - 2

father's age is 4 times my brother's age     4(y - 2)

-------------------------------

total of our four ages is 116 years.

a) Write an equation to show this.

y + 3y + (y - 2) + 4(y - 2) = 116

b) Solve the equation.

distribute

y + 3y + y - 2 + 4y - 8 = 116

combine like terms

9y - 10 = 116

add 10 to both sides

9y = 126

Divide both sides by 9

y = 14

c) How old is Sasha's father?​

4(y - 2)

4(14 - 2)

4(12)

48

Answer:

X = 29

Y = 8

Step-by-step explanation:

X - y = 21

X = 2y + 5

Substitute:

2y+5-y= 21

2y = 16

Y = 8

X-8 = 21

X = 29

Answer:

-3

Step-by-step explanation:

If lines are parallel to each other, they will never touch so the slope will be the same.

So if the first line is already given in slope intercept form, that means the -3 is the slope.

So a line parallel to this would have the slope -3 and start at a different place on the y axis.

add me as a friend if u can<3

Answer:

86

Step-by-step explanation:

Express 29% as a decimal, which is 0.29

Then divide 24.94 by 0.29, which gives you 86.

Given:

The inequality is:

[tex]y+2>\dfrac{1}{3}(6x+9)[/tex]

To find:

The inequality after isolating the y-term.

Solution:

We have,

[tex]y+2>\dfrac{1}{3}(6x+9)[/tex]

On simplification, we get

[tex]y+2>\dfrac{1}{3}(6x)+\dfrac{1}{3}(9)[/tex]

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

Subtracting 2 from both sides of the above inequality, we get

[tex]y+2-2>2x+3-2[/tex]

[tex]y>2x+1[/tex]

Therefore, the required inequality is [tex]y>2x+1[/tex].

Answer:

[tex](x-4)^2+(y+1)^2=29[/tex]

Step-by-step explanation:

We want to find a circle whose diameter has the endpoints (6, 4) and (2, -6).

Since this is the diameter, its midpoint will be the center of the circle. Find the midpoint:

[tex]\displaystyle M=\left(\frac{6+2}{2}, \frac{4+(-6)}2}\right)=(4, -1)[/tex]

So, the center of our circle is (4, -1).

Next, to find the radius, we can find the length of the diameter and divide it by half.

Using the distance formula, find the length of the diameter:

[tex]\begin{aligned} d&=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\ &=\sqrt{(2-6)^2+(-6-4)^2}\\\\&=\sqrt{(4)^2+(-10)^2}\\\\&=\sqrt{116}\\\\&=2\sqrt{29}\end{aligned}[/tex]

So, the radius will be:

[tex]\displaystyle r=\frac{1}{2}d=\frac{1}{2}\left(2\sqrt{29}\right)=\sqrt{29}[/tex]

The equation for a circle is given by:

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

Substitute:

[tex](x-4)^2+(y+1)^2=29[/tex]
