basically, you have to find the side lengths using the distance between points formula
[tex]\sqrt{|y_2-y_1|^2+|x_2-x_1|^2[/tex]
then you need the law of sines to find one of the angles
solving for the angle that formula is;
[tex]Y (gamma ) = cos^-1(\frac{a^2+b^ 2-c^2}{2ab})[/tex]
Y, or gamma, is the angle opposite C.
then i plugged it into the formula area = 1/2 a * b * sin (C)

all the math is in the picture

Answer: 16
Step-by-step explanation:
Entire garden = 7 x 4 = 28m^2
Roses = 3 x 2 = 6m^2
2 Roses = 6 x 2 = 12m^2
Entire garden - 2 Roses = Tulips
So:
28 - 12 = 16 square metres
Answer:
16m2(it's meant to be squared so small 2 on top)
Step-by-step explanation:
1x2=2 (that is for the small turquoise box)
2x7=14(main big box)
2+14=16m2(same here with the 2)

Step-by-step explanation:
The dot plot shows predictions for the winning time in a 200-meter sprint. The winner finished the race in 22.3 seconds. Find the greatest percent error for a prediction to the nearest tenth of a percent. Justify your answer.
The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).
Step-by-step explanation:Given that,
The dot plot shows predictions for the winning time in the 200-meter sprint.
The winner finished the race in 22.5 seconds.
We have to determine,
What is the greatest percent error among the predictions.
According to the question,
The true finishing time is 22.5 seconds.
The prediction furthest from this is 22.9 seconds.
This is a difference of 22.9 - 22.5 = 0.4 seconds.
Divide this over the true time value to get prediction,
0.4/22.5 = 0.0177 = 1.77 (Approximately)
Move the decimal point to the right 2 spots to get to 1.773% (Approximately 1.8%).
Hence, The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).
Hope my answer helps you.

Find the 3 smallest positive x-intercepts of the graph of
y = cos(12x) + cos(16x) and list them in increasing order.
Please give your answers as a list of x-coordinates from least to greatest.
Recall that [tex]\cos(x)+\cos(y)=2\cos \left(\frac{x+y}{2} \right)\cos \left(\frac{x-y}{2} \right)[/tex].
[tex]\cos(12x)+\cos(16x)=0 \\ \\ 2\cos(2x)\cos(14x)=0 \\ \\ \cos(2x)\cos(14x)=0[/tex]
If [tex]\cos(2x)=0[/tex], then [tex]x=\frac{\pi}{4}, \frac{3\pi}{4}, \frac{5\pi}{4}, \cdots[/tex].
If [tex]\cos(14x)=0[/tex], then [tex]x=\frac{\pi}{28}, \frac{3\pi}{28}, \frac{5\pi}{28}, \cdots[/tex].
So, the three smallest positive [tex]x[/tex] intercepts are [tex]\frac{\pi}{28}, \frac{3\pi}{28}, \frac{5\pi}{28}[/tex].

Explain how to use equivalent fractions to compare the fractions three fourths and seven twelfths. essay btw
Answer:
Step-by-step explanation:
4/12
First off, this can be reduced since both the
numerator and denominator are divisible by 4
4/12 = (4(1))/(4(3)) = 1/3
Any fraction equivalent to 1/3 will be equivalent to 4/12
... And, of course, 1/3 is equivalent to 4/12 ...
Any number or fraction does not change in value if
multiplied by 1. This means you can take your 1/3
or 4/12 and multiply it by any fraction equivalent to
1 and have an equivalent fraction..
Also note that any number divided by itself equals 1
so a/a = 1 for any given value a except a≠0
(1/3)(2/2) = 2/6
(1/3)(3/3) = 3/9
(1/3)(-2/-2) = -2/-6 = 2/6
(1/3)(4/4) = 4/12 as we know since this is the original fraction
(1/3)(5/5) = 5/15
....
....
1/3, 2/6 , 3/9, 5/15, 6/18, 7/21, ....
There are infinite equivalent fractions to 4/12.

Let theta be an angle. Then there exist constants a and b such that:
cos(theta+60 degrees)=a sin(theta) + b cos(theta)
for all theta. Enter a, b in that order.
[tex]\cos(\theta+60^{\circ})=\cos \theta \cos 60^{\circ}-\sin \theta \sin 60^{\circ} \\ \\ =\frac{1}{2}\cos \theta-\frac{\sqrt{3}}{2}\sin \theta \\ \\ \therefore a=-\frac{\sqrt{3}}{2}, b=\frac{1}{2}[/tex]
QUESTION:Suppose a cylinder has a diameter of 18 feet and a height of h feet. Which equation can be used to find V, the volume of the cylinder in cubic feet?
ANSWERS:
A V = π(18h)2V = π ( 18 h ) 2
B V = π(9)2hV = π ( 9 ) 2 h
C V = π(18)2hV = π ( 18 ) 2 h
D V = π(9h)2
Answer: B [tex]v=\pi 9^{2} h[/tex]
Step-by-step explanation:
to find volume use V=π r^2 h
if the diameter is 18 feet then the radius (r) will be half of that, 9 ft. So, to find the volume we'd just replace the r with 9 in the equation.
Answer:
B
Step-by-step explanation:
π(9)2hV = π ( 9 ) 2 h
The depth y(in feet) of a river after x years is y=0.1x+10,can you graph the linear equation?
Answer:
Step-by-step explanation:
y=0.1x+10,
slope can be made into a fraction 1/10
slope :1/10
y intercept :=10
draw the graph with the y intercept (0,10)
slope is defines as y movements/ x movements
move one up from (0,10)
and 10 to the right since it is positive making the next point you can plot (10,11)
you can check if this is correct by plugging x and y in
11=0.1(10)+10,
.1x10=1
11=1+10,
1+10 =11
11=11
do the same to the other side
move down 1 from (0,10) and move 10 to the left
next plot will be (-10,9)
you can check by pluging in x and y
9=0.1(-10)+10,
-10x.1=-1
9=-1+10,
-1+10=9
9=9
Now that you have the points you can draw the line and connect them

Describe and correct the error a student made in factoring 2x^2 + 1 1 x + 15.
(image)
The student forgot to divide the factors, 5 and 6, by the "a" value. In this case, that is 2. Then, simplify the fractions. Once we have these values, the numerator is the constant value and the denominator is the coefficient.
5/2 = 5/2 ➜ (2x + 5)
6/2 = 3 ➜ (x + 3)
This student should have factored the expression as;
(2x + 5)(x + 3)
Answer:
(2x + 5)(x+3) = 0
Step-by-step explanation:
ac = 5 * 6 = 30
b = 5 + 6 = 11
Factorizing 2x² + 11x + 15,
2x² + 6x + 5x + 15 = 0
2x(x + 3) + 5(x+3) = 0
(2x + 5)(x+3) = 0
∴ x = [tex]\frac{-5}{2}[/tex], -3
(There was a mistake probably because the quadratic equation was considered with 1 as the coefficient as x², so the factorized equation was for x² + 11x + 30. You must take the coefficient of x² as 2 instead, according to the given equation.)

The figure formed by (−3, 2), (−4, 1), and (−1, −5) is translated 3 units right and 5 units up. What are the coordinates of the new figure?
(0, 7), (−7, −4), (2, −10)
(−6, −3), (−7, −4), (−4, −10)
(0, 7), (−1, 6), (2, 0)
(−6, −3), (−1, 6), (−4, 0)
Translating the figure involves chaging the position of the figure
The coordinates of the new figure are (0, 7), (1 , 6), and (2, 0)
The coordinates of the new figure
The coordinates are given as:
(−3, 2), (−4, 1), and (−1, −5)
The rule of translation 3 units right and 5 units up is:
(x + 3, y + 5)
So, we have:
(−3 + 3, 2 + 5), (−4 + 3 , 1 + 5), and (−1 + 3, −5 + 5)
Evaluate the sum
(0, 7), (-1 , 6), and (2, 0)
Hence, the coordinates of the new figure are (0, 7), (1 , 6), and (2, 0)

Find the surface area of the cylinder. Round your answer to the nearest tenth.
radius= 3 ft height= 7 ft
Answer:
The surface area of a cylinder with radius "r" and height "h" is given by: 2πrh + 2πr^2.
So, for the given cylinder, the surface area can be calculated as:
surface area = 2 * π * 3^2 * 7 + 2 * π * 3 * 7
= 2 * π * 9 * 7 + 2 * π * 3 * 7
= 126π + 42π
= 168π
Rounding the answer to the nearest tenth, the surface area of the cylinder is approximately 527.1 square feet.

13 multiplied by x = 52 what is x?
Answer:
Step-by-step explanation:
To find the value of x, we need to divide 52 by 13.
13 multiplied by x = 52
x = 52 / 13
x = 4
So x is 4.

L of photograph = (4x+20)
B of photograph = (x+4)
Excluding the boundary/mat:
L = 4x + 20 - x = (3x + 20)
B = x - x + 4 = (4)

A store had 395 pillows in stock when the store received three shipments of 100 pillows each. How many pillows did the store have in stock after the shipments?
Answer:695 pillow
Step-by-step explanation:
You have 395 pillows, and then 3 shipments of 100 pillows come in. 3 shipments x 100 pillows = 300 pillows
395 pillow + the 300 new ones = 695 pillows.
Answer: 695
Step-by-step Explanation: They started with 395 then got three shipments that add up to 300 so 395 + 300 = 600
