Answer:
B. Tangent
Step-by-step explanation:
Tangent always makes 90 degree angle with the radius. Now in triangle let's see if it's right angled triangle or not.
To confirm if it's a right angled triangle it should follow Pythagoras Theorem.
Which states square of hypotenuse = sum of squares of other two legs
[tex]12 {}^{2} + 16 {}^{2} = 20 { }^{2} \\ 144 + 256 = 400 \\ 400 = 400[/tex]
it proves that it's a right angled triangle. Hence AB is a tangent to circle.
Yes, line AB is tangent to the circle.
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Since, Tangent always makes 90 degree angle with the radius.
Hence, in triangle we can see if it's right angled triangle or not.
Now, To confirm if it's a right angled triangle it should follow Pythagoras Theorem as;
12² + 16² = 20²
144 + 256 = 400
400 = 400
Which states square of hypotenuse = sum of squares of other two legs
it proves that it's a right angled triangle. Hence AB is a tangent to circle.
Hence, We can say that;
⇒ line AB is tangent to the circle.

the answer is b
cccxcxcxcxcxzczczxc
The percentage of the rate of decrease in the medication will be 75%. Option A is correct.
What is an exponential function?The exponential function is characterized as a function that increases quickly and whose value is always positive. With the exponent y = aˣ, where a is the constant and a>1.
It is given that the function is,f(x) = 500(0.75)ˣ. The number x represents the number of hours since the patient took their medication.
f(x) = 500(0.75)ˣ
Compare the function with the standard function as
y=baˣ
Where b is the constant value, a is the percent of the rate of decrement and x is the time period,
The value of a for the given function will be 0.75. The value is in percentage form and can be written as,
=0.75 ₓ 100
=75%
Thus, the medication's rate of decline will be 75%. Option A is correct.

Answer:
θC = π/4
Step-by-step explanation:
To find the desired angle, subtract multiplies of 2π until the angle is in the desired range.

Answer:
1. 1,538.60 cm³
2. 314.00 m³
Step-by-step explanation:
1. Given:
Diameter = 14 cm
Radius (r) = ½(14) = 7 cm
height (h) = 10 cm
π = 3.14
Volume of cylinder = πr²h
Plug in the values
V = 3.14*7²*10
V = 1,538.60 cm³
2. Given:
Radius (r) = 5 m
Height (h) = √(13² - 5²) = √144 = 12 m
π = 3.14
Volume of cone = ⅓πr²h
Plug in the values
V = ⅓*3.14*5²*12
V = 314.00 m³

Round to the Nearest tenth
Answer:
a. x=4.2, y=3
Step-by-step explanation:
We know the degrees of the two angles: Right angle (90 degrees) and 45 degrees.
The sum of the interior angles of a triangle is equal to 180 degrees, so the unknown angle is 45 degrees.
The two angles below are both 45 degrees, indicating that the side length is also 3.
So y is equal to 3, the answer can only be a.

1. The U.S. Department of Agriculture reported a random sample of 36 Americans consumed an average of 69 gallons of carbonated beverages per year. Assume that the population standard deviation is 20 gallons. Find the 95% confidence interval for the number of gallons of carbonated beverages consumed per year by Americans.(round the final answer to 3 decimal places.)
Answer:
Hence, the confidence interval is [tex](63.517,74.483)[/tex] gallons.
Given :
Sample size[tex]=36[/tex]
Sample mean [tex]=69[/tex] gallons
Standard deviation [tex]=20[/tex] gallons
So, the standard error [tex]=\frac{20}{\sqrt{36}}=20/6=3.33[/tex]
Confidence level [tex]=95\%[/tex]
To find :
The [tex]95\%[/tex] confidence interval for the number of gallons of carbonated beverages consumed per year by Americans.
Explanation :
[tex]\because[/tex] Confidence interval [tex]=(\text{Sample mean}-\text{margin error},\text{Sample mean}+\text{margin error})[/tex]
Margin error [tex]=Z_{\frac{\alpha}{2}}\times\frac{\sigma}{\sqrt{n}}[/tex]
Here, [tex]\alpha=1-95\%=1-0.95[/tex]
[tex]\Rightarrow \alpha=0.05\Rightarrow \frac{\alpha}{2}=0.025[/tex]
[tex]Z_{\frac{\alpha}{2}}=Z_{0.025}=1.645[/tex] from the [tex]z-[/tex]table.
So, Margin error [tex]=Z_{\frac{\alpha}{2}}\times\frac{\sigma}{\sqrt{n}}[/tex]
[tex]=1.645\times\frac{20}{6}=1.645\times3.33[/tex]
[tex]=5.483[/tex]
Therefore, the confidence interval is:

Is (3, –2) a solution for the following system? Yes or No x + y = 1 2x + 3y = 1
Answer:
NO
Step-by-step explanation:
Plugging in 3 for X and -2 for Y
X + Y = 12X _ 3Y = 1
3 + -2 = 12*3 + 3 * -2 = 1
1 = 36 + 3 * -2 = 1
1 = 36 + -6 = 1
1 = 30 = 1
So NO, (3, -2) is not a solution.

Step-by-step explanation:
Reflecting around x=1 never touches the y coordinate, and the x coordinate transforms - what was the distance to x=1 becomes the distance on the other side. In other words, if a point were at x=π, it's distance to x=1 was π−1 so the new location is π−1 to the left of x=1, i.e. 1−(π−1)=2−π.
