The graph shows the numbers of quarts of yellow
paint that must be mixed with different numbers of
quarts of red paint to make a certain shade of orange
paint.
Answers
Answer:
Step-by-step explanation:
The given graph is a straight line graph. The y axis represents the number of quarts of yellow paint that is mixed. The x axis represents the number of quarts of red paint that is mixed. We would write the required equation in the slope intercept form. The slope intercept form equation of a straight line is expressed as
y = mx + c
Where
m represents slope
c represents y intercept.
Slope = (y2 - y1)/(x2 - x1)
Slope = (2 - 1)/(5 - 2.5) = 1/2.5
Slope = 0.4
The straight line cuts the y axis at y = 0
It means that c = 0
Therefore, the equation is
y = 0.4x

Given GH is tangent to ⊙T at N. If m∠ANG = 54°, what is mAB ? A circle with centre T is given. GH is tangent to the circle which touches the circumference of the circle at point N. From N, a diameter NTB is drawn. A chord AN is also given, this chord forms an acute angle with tangent. mAB = 72 °
Answers
Answer:
mAB=72°
Step-by-step explanation:
Theorem:The angle between a Tangent and a Radius is 90 degrees.
Applying the above theorem therefore:
∠ANG+∠ANB=90°
54°+∠ANB=90°
∠ANB=90°-54°
∠ANB=36°
Now, Inscribed Angle=[tex]\frac{1}{2}[/tex] of the measure of the arc
Therefore:
36°=[tex]\frac{1}{2}X[/tex] mAB
mAB=36*2=72°
The measure of arcAB is 72 degrees
Circle geometryAccording to the theorem, the angle between a Tangent and a Radius is 90 degrees.
Applying the above theorem, therefore:
∠ANG+∠ANB=90°
54°+∠ANB=90°
∠ANB=90°-54°
∠ANB=36°
Since inscribed angle = of the measure of the arc
Therefore:
36°= mAB
mAB=36*2=72°
Hence the measure of arcAB is 72 degrees

Sam is fencing in his property. The length is 12 feet less than twice the width. If the total amount of fence needed is 216 feet, what is the length of the property? blank feet
Answers
Answer:
L = 68 ft
Step-by-step explanation:
To find the perimeter of something you need to add up all the sides
In this case I am assuming Sam's property is a square/rectangle
Which means the formula for the perimeter is P = 2L + 2WIf L = 2W - 12 and P = 216, we can use these values and plug them into our perimeter equation to solve for w and then solve for l
216 = 2(2W -12) + 2W → ditributing the 2 to the (2w - 12) gives us 216 = 4W - 24 + 2W → combing like terms gives us216 = 6W - 24 → adding 24 to both sides gives us 240 = 6W → dividing both sides by 6 gives us40 ft = WWith the width being solved, we can now plug that value into our length equation
L = 2(40) - 12 → distributing the 2 to the 40 gives usL = 80 - 12 → combing like terms give usL = 68 ftRewrite 2 cos 75 degrees sin 75 degrees a double angle identity
Answers
It follows from the double angle identity for sine,
sin(2x) = 2 sin(x) cos(x),
that
2 cos(75º) sin(75º) = sin(2•75º) = sin(150º)
Alternatively, recall that
sin(x + y) = sin(x) cos(y) + cos(x) sin(y)
sin(x - y) = sin(x) cos(y) - cos(x) sin(y)
Adding these together gives
sin(x + y) + sin(x - y) = 2 sin(x) cos(y)
Set x = y = 75º; then
2 sin(75º) cos(75º) = sin(75º + 75º) + sin(75º - 75º)
2 sin(75º) cos(75º) = sin(150º)
2 cos 75° . Sin 75° = Sin 150°
Notice:
Sin 150 º = Sin 30°
See that Sin 75° = Cos 15°
Cos 75° = Sin 15°
So :
2Cos 75° . Sin 75° = 2 Sin 15°Cos°15 = Sin 30°

The graph of a line passes through two given points, as shown on the graph below. What is the equation of the line
written in general form?
x - y + 5 = 0
x + y - 5 = 0
x - y - 5 = 0
Answers
Answer:
x+y-5=0
Step-by-step explanation:
From the graph, we can see that the line goes through points (0, 5) and (5, 0).
To find the slope of a line, we can use the formula (y1-y2)/(x1-x2). When we substitute the coordinates that we just found, we get (5-0)/(0-5). This equation equals 5/(-5), which equals -1. So, the slope is -1.
Then, to find the equation of the line, we can use the formula y-y1=m(x-x1).
In this equation:
y=a placeholder for the y that will be written in the actual equation
y1=needs to be replaced by a y value (you can choose which pair of coordinates it comes from)
m=slope
x=a placeholder for the x that will be written in the actual equation
x1=needs to be replaced by a x value (Needs to be in the same pair of coordinates as y1)
When we substitute the numbers we found, we will get:
y-5=-1(x-0)
y-5=-x
When we add x to both sides, we will get:
x+y-5=0

13. A rectangle has a width that is twice as long as its length and an area of 722 square inches. Find the length of the diagonal, rounded to the nearest tenth.
Answers
Answer:
The diagonal of the rectangle is approximately 42.5 inches.
Step-by-step explanation:
The area of a rectangle is given by the following formula:
area = width*length
In this case the width = 2*length, therefore we have:
area = 2*length²
722 = 2*length²
2*length² = 722
length² = 361
length = sqrt(361) = 19 inches
width = 2*length = 2*19 = 38 inches
The diagonal forms a right triangle with the sides of the rectangle, where it is the hypotenuse. Therefore we can use Pytagora's theorem:
diagonal = sqrt(length² + width²)
diagonal = sqrt(19² + 38²) = 42.485 inches
The diagonal of the rectangle is approximately 42.5 inches.
Answer:
42.5 inches
Step-by-step explanation:
l = length
w = 2l
A = 722
A = l*w
722 = l * 2l
722 = 2l^2
Divide each side by 2
361 = l^2
Take the square root of each side
sqrt(361) = l
w = 2 * sqrt(361)
We want to find the diagonal so we can use the pythagorean theorem
a^2+ b^2 = c^2 where c is the length of the diagonal
l^2 + w^2 = c^2
(sqrt(361)) ^2 + (2 sqrt(361))^2 = c^2
361+1444 = c^2
1805 = c^2
Take the square root of each side
sqrt(1805) = sqrt(c^2)
42.48529 = c
To the nearest tenth
42.5 =c
