Answer:

Chords: A chord of a circle is a segment that you draw from one point on the circle to another point on the circle.

Tangent: A tangent to a circle is a line, ray, or segment that touches the outside of the circle in exactly one point.

Step-by-step explanation:

A chord always stays inside the circle. The largest chord possible is the diameter — you can’t get any longer than that segment.

It never crosses into the circle. A tangent can’t be a chord, because a chord touches a circle in two points, crossing through the inside of the circle. Any radius drawn to a tangent is perpendicular to that tangent.

Answer:

-7 squared becomes 49, 4 times -7 is -28

49 plus -28 equals 21 and minus one is 20

If x² + y² = 1, then y = ±√(1 - x²).

Let f(x) = |x| + |±√(1 - x²)| = |x| + √(1 - x²).

If x < 0, we have |x| = -x ; otherwise, if x ≥ 0, then |x| = x.

• Case 1: suppose x < 0. Then

f(x) = -x + √(1 - x²)

f'(x) = -1 - x/√(1 - x²) = 0   →   x = -1/√2   →   y = ±1/√2

• Case 2: suppose x ≥ 0. Then

f(x) = x + √(1 - x²)

f'(x) = 1 - x/√(1 - x²) = 0   →   x = 1/√2   →   y = ±1/√2

In either case, |x| = |y| = 1/√2, so the maximum value of their sum is 2/√2 = √2.

An equation is formed of two equal expressions. The largest possible value of |x|+|y|=1.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the value of x²+y²=1. Therefore, The largest possible value of |x|+|y|=1.

Answer:

5

Step-by-step explanation:

slope = (y₂ - y₁) / (x₂ - x₁)

         = (7 - 2) / (4 - 3)

         = 5 / 1

         = 5

The slope of the line passing through the points (3 2) and (4 7) is 5

The formula for calculating the slope of a line passing through the point (3 2) and (4 7) is expressed as:

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{7-2}{4-3}\\m=\frac{5}{1} \\m=5[/tex]

Hence the slope of the line passing through the points (3 2) and (4 7) is 5

Answer:

[tex]l + w + d \leq 61[/tex]

Step-by-step explanation:

Given

Sum of l, w and d be at most 61

Required

Write as inequality

First, we need to determine the sum of l, w and d

[tex]Sum = l + w + d[/tex]

Next, we determine the type of inequality.

At most 61 means less than or equal to 61

So, the expression becomes:

[tex]Sum \leq 61[/tex]

Substitute value for Sum

[tex]l + w + d \leq 61[/tex]

Answer:

Step-by-step explanation:

h is the height of the pebble after a certain amount of time has gone by. Since we are told to find that time when the pebble is on the ground, we say that h = 0 since the height of something on the ground has no height at all. Then factor the quadratic.

[tex]-16t^2+12t+1900=0[/tex]

Throw that into the quadratic formula or however you were taught to factor irrational quadratics (maybe completing the square?) to get that

t = 11.27869 sec and t = -10.52869 sec

Since we all know that time will never carry a negative value, we will disregard it and go with 11.27869 seconds. Not sure to where you are told to round.

Answer:

y = (-5/2)x + 1

Step-by-step explanation:

We can see that the line intersects (0,1) and (2, -4). We use these points to find the slope: m = (-4-1)/(2-0) = -5/2. Also, the y-intercept is (0,1), so b = 1. Substituting these values into y=mx +b, we get y = (-5/2)x + 1.

I hope this helps! :)

Answer:

Is the number of tosses for each coin enough for the sampling distribution of the difference in sample proportions PA-PB to be approximately normal?

b. No, 20 tosses for coin A is enough, but 20 tosses for coin B is not enough.

Step-by-step explanation:

a) Data and Calculations:

The probability of coin A landing tails-side up (PA) = 0.5

Therefore, the probability of coin A landing heads-side up = 0.5 (1 - 0.5)

This is why 20 tosses for coin A is enough, since the sample proportions PA is approximately normal, symmetric, and equally distributed.  There will be equal amounts of 10 tosses (0.5 *20) for either heads-side up or tails-side up.

For coin B, the probability of landing tails-side up (PB) = 0.8

Therefore, the probability of coin B landing heads-side up = 0.2 (1 - 0-.8)

This is why 20 tosses for coin B is not enough, since the sample proportions PB is not approximately normal, symmetric, and equally distributed.  There will be 16 tosses landing tails-side up (0.8*20) and only 4 tosses landing heads-side up (0.2*20).

Answer:

-63

Step-by-step explanation:

Answer/Step-by-step explanation:

1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°

2. m<ECF = m<BCD (corresponding angles)

m<ECF = 38° (substitution)

3. m<DCF + m<ECF = 180° (linear pair)

m<DCF + 38° = 180° (substitution)

m<DCF = 180° - 38° (Subtraction property of equality)

m<DCF = 142°

The value of the card after 12 years is $669.11.

If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:

[tex]CI = P\left(1 +\dfrac{R}{100}\right)^T[/tex]

The final amount becomes:

[tex]A = CI + P\\A = P\left(1 +\dfrac{R}{100}\right)^T[/tex]

Given;

Purchase price (PV)= $800

Rate of decrease (r)= 1.5% per year

Number of periods (n)= 12 years

To calculate the value of the card after 12 years, we need to use the following formula of future value;

FV= PV / (1 + r)^n

FV= 800 / (1.015^12)

FV= $669.11
