Answer: (-.71, .71)
Step-by-step explanation:
To find the approximate coordinates of point D, we need to consider the angle ABD that measures [tex]3pi/4[/tex]radians.
Since point B is the center of the circle with radius 1 and point A lies on the x-axis at (1, 0), we can calculate the coordinates of point D using trigonometry. First, let's find the coordinates of point B, which is the origin (0, 0). Since the angle ABD measures[tex]3pi/4[/tex] radians, we know that angle ABO is pi/4 radians (complementary angle to ABD).
Using trigonometry, we can find the x-coordinate of point D based on the angle ABO: x-coordinate of D = cos(pi/4) = cos(45 degrees) = 1/sqrt(2) ≈ 0.71 Similarly, using trigonometry, we can find the y-coordinate of point D based on the angle ABO: y-coordinate of D[tex]= sin(pi/4) = sin(45 degrees) = 1/sqrt(2) ≈ 0.71[/tex] Therefore, the approximate coordinates of point D are (0.71, 0.71).

9514 1404 393
Answer:
see below
Step-by-step explanation:
Dilation changes the distance to the center of dilation by a factor equal to the scale factor.
Part A:
Point R is 2 grid squares left and 6 grid squares down from the center of dilation at (3, 7). So, point R' will be (3/2)(2) = 3 grid squares left and (3/2)(6) = 9 grid squares down from that center.
Likewise, point T is 2 square diagonals down and right of (3, 7), so T' will be 1 more square diagonal farther.
__
Part B:
As in Part A, the scale factor multiplies the distance from the center of dilation. L will be the midpoint between R and (-1, 9); M will be the midpoint between T and (-1, 9).

write the equation for 30 is 75% of what number show your work
Answer:
22.5
Step-by-step explanation:
How do you solve this question?
In order to find this answer, you must multiply the number given (30) by the percentage (75%). 75% is equal to .75. So, if you multiply 30 and 75%, you will get 22.5.

BD bisects LABC. Solve for x and find m2ABC. m_ABD = 4x-2, mZCBD=2x + 6
Answer:
i) x = 4°
ii) <ABC = 28°
Step-by-step explanation:
Given that BD bisects <ABC then it is true to say that;
Angle m < ABD=m < CBD
Hence;
4x-2 = 2x +6
4x-2x = 6 +2
2x = 8
x=8/2 = 4
x= 4°
Hence
Angle m< ABD = 4x-2 = 4*4 -2 = 16-2 =14°
Angle m < ABC = 2* 14° = 28°

You are negotiating a loan with a bank officer. The loan is at a moderate interest rate, and the term of the loan is six months. The bank officer tells you your monthly payment. Explain how you can quickly check whether or not the figure the bank officer gave you is reasonable. Choose the best answer.
A. Move the decimal point one place to the left. This is a reasonable estimate.
B. Multiply the interest rate by 100 and divide by 6. This should be the approximate amount of the payment.
C. Divide the loan amount by 6. This is the maximum you will be paying.
D. Divide the loan amount by 6. This is the minimum you will be paying.
Answer:
Step-by-step explanation:
I have this answer too and it's not B or D. So it might be A or C
To figure out if the figure the bank officer gave you is reasonable, divide the loan amount by 6. This is the minimum you will be paying.
According to the question, the tenure of the loan is six months. The borrower is expected to pay back a fraction of the principal and interest each month. This is the maximum amount that the borrower can pay.
The minimum amount that the borrower can pay each month is obtained by dividing the loan amount by six .

The hundreths place is the second digit to the right of the decimal point.
Since the number in the thousandths place is less than 5, the number in the hundreths place will remain as 9.
If the digit in the thousandths place had been 5 or greater, the answer would have been 11.20, as you would round the 9 up, consequently rounding the tenths place as well.

Answer:
Step-by-step explanation:
Given
[tex]U= \{2, 4, 6, 8, 10, 12, 14\}[/tex]
Required
Which of the sets is a subset
A set (Set A) is a said to be a subset of another set (Set B) if the content of that set (i.e. A) can be found in the other set (set B)
Using the above definition, we have:
[tex]U= \{2, 4, 6, 8, 10, 12, 14\}[/tex]
[tex]A = \{2,4\}[/tex]
A is a subset of U because 2 and 4 are in U
[tex]U= \{2, 4, 6, 8, 10, 12, 14\}[/tex]
[tex]A = \{1,3,5,7\}[/tex]
A is not a subset of U because 1,3,5 and 7 are not in U
[tex]U= \{2, 4, 6, 8, 10, 12, 14\}[/tex]
[tex]A = \{2,3,4\}[/tex]
A is not a subset of U because 1,3,5 and 7 are in U
Hence, option A answers the question.

An endangered species of fish has a population that is decreasing exponentially (A - Apekt). The population 5 years ago was 1800. Today, only 800 of the
fish are alive. Once the population drops below 100, the situation will be irreversible. When will this happen, according to the model? (Round to the nearest
whole year.)
O 12 years from today
15 years from today
O 14 years from today
O 13 years from today
Answer:
13 years.
Step-by-step explanation:
I don't understand the original equation you entered, so I'm going to use another one.
[tex]A = A_0e^k^t[/tex]
Where A = initial population
A₀ = current population
e = Euler's constant
k = rate of decrease
t = time in years
Let's start off with what we know.
Today there are 800 fish left:
A₀ = 800
There were 1800 fish 5 years ago:
t = -5
A = 1800
The equation now looks like [tex]1800=800e^-^5^k[/tex]
First we find the rate of decrease.
[tex]\frac{1800}{800} = e^-^5^k[/tex]
⇒ [tex]2.25 = e^-^5^k[/tex]
⇒ [tex]ln(2.25) = -5k[/tex]
⇒[tex]\frac{ln(2.25)}{-5}[/tex]=k
⇒ k = -0.1621
The question asks when it will drop below 100, so make it equal to 100.
⇒[tex]100=800e^-^0^.^1^6^2^1^*^t[/tex]
⇒[tex]100/800=e^-^0^.^1^6^2^1^*^t[/tex]
⇒[tex]ln(1/8)=-0.1621*t[/tex]
⇒[tex]\frac{ln(1/8)}{-0.1621}[/tex] = t = 12.821
To the nearest year this is 13.
Which equation represents a line with slope 2/3 and y-intercept −6?
2x −3y= 18
3x −2y= 6
3x −2y= 12
2x +3y=−6
Which graph represents a function, f(x) that has a slope of 3 units and f(0) = 14?
Answer:A
Step-by-step explanation:
Since the slope is 3, hence it passes through the point (-4.67, 0). Hence the equation of the line is y = 3x + 14.
A linear equation is in the form:
y = mx + b;
where m is the slope, b is the y intercept and y, x are variables.
Since f(0) = 14, hence the y intercept is 14, hence the graph passes through point (0, 14).
Also, since the slope is 3, hence it passes through the point (-4.67, 0). Hence the equation of the line is y = 3x + 14.
Therefore the graph is attached below.

The CPU of a personal computer has a lifetime that is exponentially distributed with a mean lifetime of six years.
A) What is the probability that the CPU fails within three years? (6 points) (Round your answer to 4 decimal places)
B) Assume that your corporation owned 10 CPUs, and assume that the CPUs fail independently. What is the probability that at least one fails within three years? (8 points) (Round your answer to 4 decimal places)
Answer: 0.393 ; 0.9933
Step-by-step explanation:
Given that :
Mean lifetime follows an exponential distribution (m) = 6
a. What is the probability that the CPU fails in the next three years?
Using the poisson distribution formula :
1 - e^-λt
λ = 1/m = 1 / 6 = 0.1667
Probability of failure in next 3 years :
P(X < 3) = 1 - e^-λx
P(X < 3) = 1 - e^-0.1667*3
P(X < 3) = (1 - e^-0.5)
P(X < 3) = 1 - 0.6065306
P(X < 3) = 0.3934693
= 0.3935
b. Assume that your corporation has owned 10 CPUs for three years, and assume that the CPUs fail independently. What is the probability that at least one fails within the next three years?
Number of pc owned = 10
CPU failure is indepndent
Probability of atleast one fails :
1 - P(X ≥ 3)^n
P(X ≥ 3) = 1 - P(X < 3)
P(X ≥ 3) = 1 - 0.3935 = 0.607
Hence,
1 - P(X ≥ 3) = 1 - 0.6065^10
1 - P(X ≥ 3) = 1 - 0.0067345
1 - P(X ≥ 3) = 0.993265
= 0.9933
