When a tangent line and a radius intersect on the surface of a circle,
which of the following holds true?
Answer:
c
Step-by-step explanation:
When a tangent line intersects with a radius of a circle at the point of tangency, they will be perpendicular. Tangent lines that meet two different circles. Since a tangent line is perpendicular to the radius of the circle, extend the radius outside of the circle.
Which function represents the graph
The absolute value function represented by the graph is:
y = -3*|x|
So the correct option is B.
Which function represents the graph?
In the graph, we can see a "V" shape, which belongs to the absolute value functions, but this graph opens down, so our function will be something like:
y = -a*|x - b|
The value of b is the value of x where we have the vertex, in this case, is at x = 0, so b = 0
y = -a*|x|
To get the value of 1, we ise one of the points that we can see on the graph. For example, for x = 1, we have y = -3, replacing that we get:
-3 = -a*|1| = -a
3 = a
So we can conclude that our function is:
y = -3*|x|
So the correct option is B.

A roof is constructed as shown. What is the length of the slope of the roof? Round to the nearest 10th
Answer:
Length of slope = 15.8 yd
Step-by-step explanation:
using Pythagoras theorem,
?² = 13² + 9²
?² = 169 + 81
? = √250
? = 15.8 yd
Step-by-step explanation:
According to Pythagoras theorem ,
Hypotenuse ² = Perpendicular ² + base ²
Here , we have to find the hypotenuse
perpendicular = 13ydbase = 9ydputting the known values ,
Hypotenuse² = (13yd)²+ (9yd)²
Hypotenuse² = 169+81
Hypotenuse² = 250 yd
Hypotenuse = √250 yd
Hypotenuse = 15.8 yd
The two cones below have the same radius, height, and volume. are the two cones congruent? explain and include details to support your claim.
The cones are not congruent because one cone is oblique, which makes the length of the slant heights different.

Answer:
Sample Response: The cones are not congruent because one cone is oblique, which makes the length of the slant heights different. Having the same radius, height, and volume does not make the cones congruent when the corresponding slant heights are not equal. Congruent cones must have congruent corresponding slant heights, with all other corresponding parts being congruent.

Which transformation or sequence of transformations would produce an image that is not congruent to its pre‐image?
A translation of (x − 2, y + 9)
A translation followed by a rotation
A rotation of 270 degrees about the origin
A dilation followed by a translation
Answer:
A dilation followed by a translationStep-by-step explanation:
A dilation would change the size of the figureHence, on changing it, the transformation will form an image that is not congruent to its pre-imageThe transformation or sequence of transformations that would produce an image that is not congruent to its pre-image is:
A dilation followed by a translation.
If we follow a dilation with a translation, the image will be both resized and shifted. The combination of these transformations will result in an image that is not congruent to its pre-image.
On the other hand:
A translation of (x − 2, y + 9) will shift the object without changing its size or shape. The resulting image will be congruent to the pre-image.
A translation followed by a rotation can result in a congruent image if the rotation angle and translation distance are appropriately chosen. It depends on the specific values used in the transformation.
A rotation of 270 degrees about the origin will preserve the shape and size of the object. The resulting image will be congruent to the pre-image.

Answer:
y = x² + 2
y = -5/x
Step-by-step explanation:
Linear & Nonlinear Definition:
Linear is something that is associated with a straight line such as linear equation or function. That means the highest degree of equation has to be 1 or only x.Nonlinear is something that does not form a line graph such as parabola, cubic, exponential, etc.From choices:
Both y = 2x+7 and y = 6(x-1) are linear because they have highest degree as 1 which is only x and these equations are known as linear function.However, both y = x²+2 and y = -5/x are nonlinear because y = x²+2 forms parabola which is a curve graph and also has highest degree of 2. As for y = -5/x, this is called fractional function which also forms curve graph and the degree of this equation is -1 via law of exponent.Therefore, y = x²+2 and y = -5/x are nonlinear.

Skip to the bottom for image examples, read on for definitions.
Acute angles are angles less than 90 degrees.Right angles are exactly 90 degrees.Obtuse angles are 91 degrees or more.For example, I sliced a pie, and it was an acute angle. Or I could have bought a taco and that taco has an obtuse angle, while if I just picked up a mini-square-cake, it is made of many right angles. And yes, I did draw those images myself as examples.

Derek lives in canada and enjoys herb gardening. his american friend sent him a guidebook for growing fresh herbs. the book says that it is best to cut bay shoots when they are 3.25 in long. if 1 mm is equivalent to 0.03937 in, how many millimeters long should the bay shoots be when derek cuts them? a. 8.26 mm b. 12.80 mm c. 82.55 mm d. 95.67 mm
When the bay shoots are 82.55 mm, Derek should cut them according to the guidebook for growing fresh herbs option (c) is correct.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.
The book says that it is best to cut bay shoots when they are 3.25 in long.
As it is given that the:
1 mm = 0.03937 in
To find how many millimeters long should the bay shoots be when Derek cuts them, we must convert 3.25 in to mm
From the 1 mm = 0.03937 in, we can find how many mm is there in 1 in;
[tex]\rm 1 \ in= \frac{1}{0.03937} \ mm[/tex]
To convert 3.25 in into mm, we must multiply it by 1/0.03937
= 3.25×(1/0.03937)
= 82.55 mm
Thus, when the bay shoots are 82.55 mm, Derek should cut them according to the guidebook for growing fresh herbs option (c) is correct.

[note: the hypotenuse, c, is always the longest side]
102 + (x-2)2 = x2
100 + x2 -4x + 4 = x2 [expand using F-O-I-L]
100 -4x + 4 = 0 [subtract x2 from both sides]
104 - 4x = 0 [collect terms]
-4x = -104 [subtract 104 from both sides]
x = 26 [divide both sides by (-4)]

Which function has a range of {y|y ≤ 5}? f(x) = (x – 4)2 5 f(x) = –(x – 4)2 5 f(x) = (x – 5)2 4 f(x) = –(x – 5)2 4
The function range of {y|y ≤ 5} is f(x)=-(x-4)^4+5.
Since the range has less than a sign, this means that the parabola is
facing downwards and it means that a is negative.
The range is given by

What is the vertex form of a quadratic equation?[tex]f(x)=a(x-h)^2+K[/tex]
Since the range is

b) A different pattern is made using 20 straight lines
and 14 arcs.
The straight lines and arcs are made from metal.
20 straight lines cost £12
cost of one straight line : cost of one arc = 2 : 3
Work out the total cost of metal in the pattern.
Answer:
total cost= 24.6
Step-by-step explanation:
12 ÷ 20 = 0.6 per straight line
arc 0.6 × 3/2 = 0.9
12 + 0.9 × 14
12 + 12.6 = 24.6
The required cost of the metal used in the pattern is £24.6.
Given that,
A different pattern is made using 20 straight lines and 14 arcs.
The straight lines and arcs are made from metal. 20 straight lines cost £12 cost of one straight line is cost one arc = 2 : 3.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the cost of the total arcs be x,
As per the given condition,
The cost of the one straight line is 12/20 and cos if the one arc is x/14,
According to the question,
[12/20]/[x/14] = 2/3
12×14/20 = 2x / 3
x = £12.6
The total cost of a metal arc is £12.6
And the total cost of the metal line in the pattern is = £12.
Total cost of metal = 12 + 12.6 = £24.6
Thus, the required cost of the metal used in the pattern is £24.6.
