Wen painted 3/10 of her living room yesterday and 4/10 to today. What fraction of the room has she painted so far? ​

Answer:

[tex]x=\frac{\pi }{6} ,\frac{7\pi }{6}[/tex]

Step-by-step explanation:

[tex]3*cot^2x-1=0\\\\3*cot^2x=1\\\\cot^2x=\frac{1}{3} \\\\cot(x)=\sqrt{\frac{1}{3} } \\\\cot(x)=\frac{1}{\sqrt{3} } \\\\\frac{1}{tan(x)}=\frac{1}{\sqrt{3} } \\\\tan(x)=\sqrt{3} \\[/tex]

x=tan^-1([tex]\sqrt{3}[/tex])

It has to be in Quadrant 1  [tex]\frac{+}{+} =+[/tex] or 3 [tex]\frac{-}{-}=+[/tex] for positive.

[tex]x=\frac{\pi }{6} ,\frac{7\pi }{6}[/tex]

Unless that incorrect due to tan(x) range is [tex]-\frac{\pi }{2} \leq x\leq \frac{\pi }{2}[/tex]. Then the only answer is [tex]x=\frac{\pi }{6}[/tex]

Answer:

26

Step-by-step explanation:

Assume the table is a rectangle.

A rectangle has 2 sides with the length of the length and 2 sides with the length of the width.

perimeter = sum of the lengths of the sides

perimeter = 9 + 9 + 4 + 4

perimeter = 26

Answer:

26

Step-by-step explanation:

Assuming the table is rectangular...

Rectangles = 4 sides

2 sides = 9

Other 2 sides = 4

Perimeter = adding up the sides

9+9+4+4=26

The equation of the line of best fit in the table given regarding the weights will be y = 0.77x - 1.1

From the information given, the equation of the line of best fit in the table given regarding the weights is given and the correlation coefficient is 0.99.

The relationship is strongly positive as it's close to 1. The slope of the best fit gives the change in dosage for for an increase in the weight of the patient.

When a patient who weighs 140 pounds is prescribed 135 milligrams of medicine, it affects the line of best fit as it increases the intercept but decreases the slope.

Answer:

A

Step-by-step explanation:

It is A because the negative in front of the 4 shows the curve was REFLECTED over the x-axis. The +1/2 in the parenthesis with the x shows the curve was translated (shifted or slid) to the LEFT 1/2 unit and the +3 at the end of the equation shows the whole thing was translated/shifted/slid UP 3 units. These transformations all together make the equation in A match the curve given.

Check the picture below.

Answer:

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

Step-by-step explanation:

From the graph/image that you have provided said translated shift of

f(x) -> g(x)

f(x) = x^2 , g(x) = a(x -h)^2 +k

h is shift right/left

k is shift up/down.

It appears that the shift is left 2 and up 1.

h = -2 and k = 1

g(x) = (x - (-2))^2 +1

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

The probability that Kate chooses a two-digit number or a prime number randomly from the month of August is 7/31.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

Kate is randomly choosing a date in the month of August. This date must be a two-digit number or a prime number.

The two digit prime numbers are 7(11,13,17,19,23,29,31). Thus, the probability is,

[tex]P=\dfrac{7}{31}[/tex]

Hence, the probability that Kate chooses a two-digit number or a prime number randomly from the month of August is 7/31.

[tex]AC = 12.12[/tex]

Step-by-step explanation:

Step 1:  Determine side AC

[tex]Pythagorean\ theorem[/tex] → [tex]a^2 + b^2 = c^2[/tex]

[tex](AC)^2 + (CB)^2 = (AB)^2[/tex]

[tex](AC)^2 + (7)^2 = (14)^2[/tex]

[tex](AC)^2 + 49 = 196[/tex]

Step 2:  Subtract 49 from both sides

[tex](AC)^2 + 49 - 49 = 196- 49[/tex]

[tex](AC)^2 = 147[/tex]

Step 3:  Square root both sides

[tex]\sqrt{(AC)^2} = \sqrt{147}[/tex]

[tex]AC = 12.12[/tex]

Answer:  [tex]AC = 12.12[/tex]

[tex]x=\dfrac{\log(75.2)}{4\log(8)}[/tex]

Step-by-step explanation:

[tex]\begin{aligned}5 \cdot 8^{4x} & =376\\8^{4x} & = \dfrac{376}{5}\\8^{4x} & =75.2\end{aligned}[/tex]

Taking logs of both sides:

[tex]\implies \log(8)^{4x}=\log(75.2)[/tex]

Using the power log rule [tex]\log_a(x)^n=n\log_a(x)[/tex] :

[tex]\implies 4x\log(8)=\log(75.2)[/tex]

Solving for x:

[tex]\begin{aligned}\implies 4x\log(8) & =\log(75.2)\\\\ 4x & =\dfrac{\log(75.2)}{\log(8)}\\\\x & =\dfrac{\log(75.2)}{4\log(8)}\\\end{aligned}[/tex]

Answer:

To find coterminal angles, add or subtract 360 degrees of the terminal angle as many times possible.

To find radians, use this formula:

Degrees × π/180°

Coterminal angles point in the same exact direction.

In degree mode, you can add on 360 degrees to get a coterminal angle.

Example: 90 degrees is coterminal to 450 degrees because 90+360 = 450. Both angles 90 and 450 point directly north.

You can also subtract 360 from the angle to get a coterminal counterpart.

Example: Given the angle 700, it is coterminal to 340 since 700-360 = 340

This process of adding or subtracting 360 can be done as many times as you like.

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

For radian mode, you'll add or subtract 2pi radians to get a coterminal angle. This is because 2pi radians = 360 degrees by definition.

Examples:
