ABC and ADC are triangles. The area of triangle ADC is 52m^2. Work out the length of AB
Answer:
Tthe length of AB is 13.6 cm
Step-by-step explanation:
Step 1: calculate length CD using the area of a triangle
[tex]A = \frac{1}{2} \times (AD \times CD) \times \ sine (D)\\\\52 = \frac{1}{2} \times (12 \times CD) \times \ sine (102)\\\\52 = 6CD \times 0.978\\\\52 = 5.868CD\\\\CD = \frac{52}{5.868} \\\\CD = 8.862 \ cm[/tex]
Step 2: calculate length AC using Cosine rule;
[tex]AC^2 = AD^2 + CD^2 - 2(AD \times CD)cos (D)\\\\AC^2 = 12^2 + 8.862^2 - 2(12 \times 8.862)cos(102)\\\\AC^2 = 222.535 - 2(-22.11)\\\\AC^2 = 222.535 + 44.22\\\\AC^2 = 266.755\\\\AC = \sqrt{266.755} \\\\AC = 16.33 \ cm[/tex]
Step 3: Apply sine rule to calculate length AB;
[tex]\frac{AB}{sin \ 46} = \frac{AC}{sin \ 120} \\\\AB = \frac{sin \ 46 \ \ \times \ \ AC}{sin \ 120} \\\\AB = \frac{sin \ 46 \ \ \times \ \ 16.33}{sin \ 120} \\\\AB = 13.56 \ cm \\\\AB = 13.6 \ cm[/tex]
Therefore, the length of AB is 13.6 cm

There were 780 fish in the lake. After a year, the population increases by 23% How many fish are in the lake? Round tot he nearest whole number.
Answer:
There are 959 fish in the lake.
Step-by-step explanation:
According to the information provided, to be able to find the number of fish in the lake, you have to calculate 23% of the amount of fish in the lake and add that result to the amount of fish in the lake:
780*23%=179
780+179=959
According to this, the answer is that there are 959 fish in the lake.

Answer:
Fraction- 12/14 (6/7)
Decimal- 0.85 or 0.86 (depending if you want to round up)
Percent- 85%
Step-by-step explanation:
Add all of the CD's that arent comedy then put the total number of CD's below. And then take 12/14 and apply it as a decimal and percent and also simplify it if needed.
Which function represents the exponential function f(x) = 3x after a vertical stretch by a factor of 8 and a reflection across the x-axis?
Answer:
g(x)=-8(3^x)
Step-by-step explanation:
Given: f(x)=3^x
Multiply by 8: f(x)=8(3^x)
Negate function: g(x)=-8(3^x)
The function represents the exponential function f(x) = 3x after a vertical stretch by a factor of 8 and a reflection across the x-axis will be g(x)=-8(3ˣ).
What is an exponential function?It is defined as a function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x.where a is a constant and a>1
It is given that, the function represents the exponential function f(x) = 3x.
We have to find the function after a vertical stretch by a factor of 8 and a reflection across the x-axis.
We have to do geometric transformation, It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
Thus, the function represents the exponential function f(x) = 3x after a vertical stretch by a factor of 8 and a reflection across the x-axis will be g(x)=-8(3ˣ).

The probability that the sum of the two cubes will be a prime number is 0.33.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
Henry has 2 six-sided number cubes, one red, and one blue.
The faces of the red cube are numbered 1-6.
The faces of the blue cube are numbered 7-12.
Henry tosses both number cubes.
Sample space for the experiment = {(1, 7), (1, 8), .........., (1, 12), (2, 7), (2, 8), ......., (2, 12), .........., (6, 7), ...........,(6, 12)}
Total number of outcomes = 36
Least sum is 1 + 7 = 8 and greatest sum is 6 + 12 = 18
Prime numbers in between 8 and 18 are 11, 13 and 17.
Sum will be prime numbers for the outcomes,
{(1, 10), (1, 12), (2, 9), (2, 11), (3, 8), (3, 10), (4, 7), (4, 9), (5, 8), (5, 12), (6, 7), (6, 11).
Number of outcomes which sum are prime numbers = 12
Probability = 12/36 = 1/3 = 0.333
Hence the probability is 0.33.

Answer:
-3x^2+16x+64
Step-by-step explanation:
First, you need to find the area of both areas (the total area and the area of the unshaded part). Let's find the total area.
(x+8)(x+8)=x^2+16x+64
The total area is x^2+16x+64
(2x)(2x)=4x^2
The area of the unshaded part is 4x^2
Now we have to subtract to find the area of the shaded part.
x^2+16x+64-4x^2
-3x^2+16x+64
That is the answer
Hope this helped!! :D
