Answer:
Step-by-step explanation:
First, we need to understand what a conjecture means, we can take a conjecture to mean the use of observed patterns or foundational knowledge about a certain phenomenon or thing to make a decision or make a logical conclusion about such thing.
Hence, when making Justification about a conjecture, we need to take into cognizance some potent things :
1.) There must be an observed pattern, relationship between the observation upon which a conjecture is to be made. As this pattern are key to our reasoning and decision.
2.) Also, our final conclusion or conjecture will be based on the pattern observed and not on some random thought.

Find the area of the polygon
Answer:
[tex] 687.5 \: {ft}^{2} [/tex]
Step-by-step explanation:
Area of polygon = Area of square + Area of triangle
[tex] = {25}^{2} + \frac{1}{2} \times 25 \times (30 - 25) \\ \\ = 625 +\frac{1}{2} \times 25 \times5 \\ \\ = 625 + \frac{1}{2} \times 125 \\ \\ = 625 + 62.5 \\ \\ = 687.5 \: {ft}^{2} [/tex]

Paul built a triangular garden in his backyard, which is enclosed by a rectangular fence. How much of the backyard is not covered by the garden
Answer: 476m²
Step-by-step explanation:
Find the area of the triangle and then subtract it from the area of the rectangle.
Area of triangle = 1/2 * base * height
= 1/2 * 8 * 6
= 24m²
Area of rectangle:
= Length * Width
= 25 * 20
= 500m²
Area not covered by garden:
= 500 - 24
= 476m²
Find the interest on naira 40000.00 for 2 years at 20% per annum compound interest. Please I need the answer ASAP
Given:
Principal value = 40000
Rate of compounded interest = 20%
Time = 2 years
To find:
The interest.
Solution:
Formula for amount is
[tex]A=P\left(1+\dfrac{r}{100}\right)^t[/tex]
Where, P is principal, r is rate of interest and t is time in years.
Putting the given values, we get
[tex]A=40000\left(1+\dfrac{20}{100}\right)^2[/tex]
[tex]A=40000\left(1+\dfrac{1}{5}\right)^2[/tex]
[tex]A=40000\left(\dfrac{6}{5}\right)^2[/tex]
[tex]A=40000\left(\dfrac{36}{25}\right)[/tex]
[tex]A=57600[/tex]
Now, the formula for interest is
[tex]I=A-P[/tex]
[tex]I=57600-40000[/tex]
[tex]I=17600[/tex]
Therefore, the amount of compound interest is 17,600.

Find the exact value pf cos 2x if sin x = - 4/5 (Quadrant III)
Answer:
[tex]\displaystyle \cos(2x)=-\frac{7}{25}[/tex]
Step-by-step explanation:
We want to find:
[tex]\displaystyle \cos(2x)\text{ given that }\sin(x)=-\frac{4}{5}[/tex]
And x is in QIII.
Recall that sine is the ratio of the opposite side to the hypotenuse.
Therefore, the adjacent side is (we can ignore the negative for now).
[tex]a=\sqrt{5^2-4^2}=\sqrt{25-16}=\sqrt{9}=3[/tex]
So, the adjacent side is 3, the opposite side is 4, and the hypotenuse is 5.
Using the double angle identity, we can rewrite:
[tex]\cos(2x)=\cos^2(x)-\sin^2(x)[/tex]
Since x is in QIII, cosine is positive, sine is negative, and tangent is negative.
Using the above values, we can conclude that:
[tex]\displaystyle \cos(x)=\frac{3}{5}\text{ and } \sin(x)=-\frac{4}{5}[/tex]
Substitute:
[tex]\displaystyle \cos(2x)=\Big(\frac{3}{5}\Big)^2-\Big(-\frac{4}{5}\Big)^2[/tex]
Evaluate:
[tex]\displaystyle \cos(2x)=\frac{9}{25}-\frac{16}{25}=-\frac{7}{25}[/tex]

60°
x + 83
40°
A) 7
C) -5
B) -11
D) -3
Answer:
-3
Step-by-step explanation:
Using the Triangle Sum Theorem, we can prove that m<A + m<B + m<C = 180⁰. Looking at the triangle above, it has given us two measurements. We have to find the third measurement. In order to find the third measurement we will use the Triangle Sum Theorem.
m<A + m<B + m<C = 180⁰
x + 83 + 60⁰ + 40⁰ = 180⁰
x + 183⁰ = 180⁰
x + 183⁰ - 183⁰ = 180⁰ - 183⁰
x = -3
Now plug in -3 in the x place.
x + 83
-3 + 83 = 80⁰
Let us make sure that our Triangle Sum Theorem is right.
m<A + m<B + m<C = 180⁰
80⁰ + 60⁰ + 40⁰ = 180⁰
180⁰ = 180⁰
So this makes our answer true. Hope this helps, thank you :) !!

2x - 3 > -4x + 6 whats the answer to this
Answer:
x > 3/2
Step-by-step explanation:
2x - 3 > -4x + 6
Add 4x to each side
2x+4x - 3 > -4x+4x + 6
6x-3 > 6
Add 3 to each side
6x-3+3>6+3
6x>9
Divide each side by 6
6x/6 >9/6
x > 3/2
The letters P-R-O-B-A-B-I-L-I-T-Y are written on a set of cards. You mix the cards thoroughly. Without looking, you draw one letter then you draw another without replacing the first. Find the probability that you will select a P followed by a Y.
P(P, then Y) =
Answer:
P(P, then Y)=(1/11)(1/10)=1/110
Step-by-step explanation:
The number of letters in probability is 11.
There is 1 P.
The probability of drawing a P on draw 1 is the number of ways of drawing a P, which is 1, divided by the number of ways of drawing any letter, which is 11. Thus:
Probability of drawing a P on the first draw is 1/11.
There are now 10 letters left. There is 1 Y. so
Probability of drawing a Y on the second draw given that you drew a P on the first draw is 1/10.
The probability of drawing a P on the first draw and a Y on the second draw is
(probability of a P on draw 1)(probability of drawing a Y on draw 2, given a P on draw 1)
P(P, then Y)=(1/11)(1/10)=1/110
