Answer:

[tex]\textsf{D.}\quad\dfrac{b}{\sqrt{a^2+b^2}}[/tex]

Step-by-step explanation:

Tan trig ratio

[tex]\tan(x)=\sf \dfrac{O}{A}[/tex]

where:

Using the given information:

[tex]\implies x=\tan^{-1}\left(\dfrac{a}{b}\right)[/tex]

[tex]\implies \tan(x)=\tan\left(\tan^{-1}\left(\dfrac{a}{b}\right)\right)[/tex]

[tex]\implies \tan(x)=\left(\dfrac{a}{b}\right)[/tex]

Comparing this with the trig ratio, we can say that:

[tex]x[/tex] is the angle opposite side [tex]a[/tex]

Cos trig ratio

[tex]\cos(x)=\sf \dfrac{A}{H}[/tex]

where:

Therefore:

[tex]\implies \cos\left(\tan^{-1}\left(\dfrac{a}{b}\right)\right)=\cos(x)= \dfrac{b}{\sqrt{a^2+b^2}}[/tex]

10 + 3 = 13

13 + 13 = 26 (10 + 10 + 3 + 3)

Answer:

Step-by-step explanation:

Sum of all angles of triangle = 180

17x + 10x -5 +  50 = 180

Combine like terms

27x + 45 = 180

To find the valu of x, we have to isolate x. To isloate x

Step 1: Subtract 45 from both sides

           27x = 180 - 45

           27x = 135

Step 2: Divide both sides by 27

               x = 135/27

x = 5

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

[tex]{y|y \leq k}[/tex]

[tex]f(x)=a(x-h)^2+K[/tex]

Since the range is

[tex]{y|y \leq 5},[/tex]

This means that k = 5 , and since a is negative

The correct function is

[tex]f(x)=-(x-4)^4+5[/tex]

Answer: B: (f(x) = –(x – 4)2 + 5)

Step-by-step explanation:

When the bay shoots are 82.55 mm, Derek should cut them according to the guidebook for growing fresh herbs option (c) is correct.

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.

[tex]5\sqrt{2}[/tex] or 7.07 (rounded to hundredths place)

Step-by-step explanation:

what is the "cord I ate plane"?

The absolute value function represented by the graph is:

y = -3*|x|

So the correct option is B.

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.

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.

Answer:

10 hours = 60 mph

you will need to go 60 mph to make the trip 10 hours

explaination:

Multiplying the amount of hours and the mph, 12 times 50 is 600 miles.

10 times 60 is 600 miles. They both have the same answer, but 60 mph is the fastest. 60 mph is how fast you would need to go to make it in 10 hours.

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.

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

putting the known values ,

Hypotenuse² = (13yd)²+ (9yd)²

Hypotenuse² = 169+81

Hypotenuse² = 250 yd

Hypotenuse = √250 yd

Hypotenuse = 15.8 yd

Hey i believe this is the answer

Step-by-step explanation:

Take a look at the screenshot

Also Desmos graphing calculator is a big help :) It might make you a little more confident

Answer:First, draw a picture.

Distance on ground = 10 feet

Length of ladder (hypotenuse) = x          [unknown for now]

Height on wall =  x-2

The Pythagorean theorem says, for a right triangle:    a2+b2=c2

    [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)]

Check:

  Is   102 + 242 = 262   ?

The cones are not congruent because one cone is oblique, which makes the length of the slant heights different.

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

The two cones below have the same radius, height, and volume.

One cone is oblique.

The cones have different slant heights.

The lengths of all corresponding edges are not equal.

Since, Congruent cones must have congruent corresponding measures, including slant height.

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.

Since the data-set contains outliers, the median is a better choice, and it is given of 10 ounces.

It depends if the data-set contains outliers or not.

In this problem, the weights of 4 and 5 ounces are outliers, hence the median should be used. There are 19 values, hence the median will be given by the 10th value, which is 10. Hence the median is of 10 ounces.
