For what values of k the relation R:{(k2 , 5), (3k, 6)} is not a function?

Answers

Answer 1

Answer:

[tex]k=0[/tex] and [tex]k=3[/tex].

Step-by-step explanation:

To this relation be a function, the horizontal coordinates can't be equal. So, let's find the value of [tex]k[/tex] that makes those coordinates equal.

[tex]k^{2}=3k\\ k^{2}-3k=0\\k(k-3)=0\\[/tex]

Using the null factor property, we have

[tex]k=0\\k-3=0 \implies k=3[/tex]

Therefore, the given relation is not a function when [tex]k=0[/tex] and [tex]k=3[/tex].

Answer:

-The measure of [tex]\angle A[/tex] :

[tex]\angle A = 144\textdegree[/tex]

-The measure of [tex]\angle B[/tex] (if needed):

[tex]\angle B = 144\textdegree[/tex]

Step-by-step explanation:

-Set the measure of [tex]\angle A[/tex] on one side and set the measure of [tex]\angle B[/tex] on the other side and it will be written as:

[tex]10x + 24 = 6x + 72[/tex]

-Then, solve for [tex]x[/tex] :

[tex]10x + 24 = 6x + 72[/tex]

[tex]10x + 24 - 6x = 6x - 6x + 72[/tex]

[tex]4x + 24 = 72[/tex]

[tex]4x + 24 - 24 = 72 - 24[/tex]

[tex]4x = 48[/tex]

[tex]\frac{4x}{4} = \frac{48}{4}[/tex]

[tex]x = 12[/tex]

-After you have found the value of [tex]x[/tex], plug in both the measure of [tex]\angle A[/tex] and [tex]\angle B[/tex] in order to get the actual angle measurement of [tex]\angle A[/tex] and [tex]\angle B[/tex] :

Finding the measure of [tex]\angle A[/tex] :

[tex]\angle A = 10(12) + 24[/tex]

[tex]\angle A = 120 + 24[/tex]

[tex]\angle A = 144\textdegree[/tex]

Finding the measure of [tex]\angle B[/tex] :

[tex]\angle B = 6(12) + 72[/tex]

[tex]\angle B = 72 + 72[/tex]

[tex]\angle B = 144\textdegree[/tex]

-Notice: That reason why both [tex]\angle A[/tex] and [tex]\angle B[/tex] have the same measurements, its because they are Alternate Exterior Angles, based on the diagram shown.

A bag of potatoes weights 30 lb. If 74% of a potato is water, how many pounds of water are there in the bag?

Answers

Answer: There are 22.2 pounds of water in the bag.

Step-by-step explanation:

Hi, to answer this question we simply have to multiply the total weight of the bag by the water percentage in decimal form (divided by 100).

Mathematically speaking:

30 x (74/100) = 30 x 0.74 =22.2 pounds

There are 22.2 pounds of water in the bag.

If a right triangle's hypotenuse is 17 units long, and one of its legs is 15 units long, how long is the other leg?

Answers

Answer:

8 units

Step-by-step explanation:

Hello!

So, there's a formula we can apply to right-angled triangles: Pythagorean's theorem. It states that  c = [tex]\sqrt{{a}^2 + b^{2} }[/tex], where c is the hypotenuse and a and b are the legs of the triangle.

So, from the problem,  if c = 17 and a = 15, then, we're solving for b. So we'll rewrite the theorem to solve for b.

[tex]{c}^2 = {a}^2+{b}^2\\{c}^2-{a}^2={b}^2\\{b} = \sqrt{{c}^2-{a}^2}[/tex]

Okay, so now we have isolated the theorem for b. Let's plug in our values for c and a.

[tex]b = \sqrt{{17}^2-{15}^2}\\b = \sqrt{289-225}\\b = \sqrt{64}\\b = 8[/tex]

So, using the theorem, we found b = 8. To check our work, let's plug in b and a and solve for c.

[tex]c = \sqrt{{a}^2+{b}^2}}\\c = \sqrt{{15}^2+{8}^2}\\c = \sqrt{225+64}\\c = \sqrt{289}\\c = 17\\[/tex]

So, we got our hypotenuse to equal 17 units, which is correct! So, our b is correct too. Awesome

What is the value of y?

A. 630
B. 126°
C. 73°
D. 54°

Answers

Answer:

y = 63

Step-by-step explanation:

The sum of the angles of a triangle is 180

54+y+y = 180

Combine like terms

2y+54 = 180

Subtract 54 from each side

2y+54-54= 180-54

2y =126

Divide each side by 2

2y/2 = 126/2

y =63

Answer:

A. 63 degrees

Step-by-step explanation:

All angles added together would equal 180. We have two angles that equal y and a third that has 54. Our first step:

180-54=126

Both of the y angles equal 126. We want a separate value though, so we divide this by two.

126/2=63

Thus, A is our answer

The volume of the following figure is 240in² Which of the following is the missing side length?

Answers

Answer:

8 in

Step-by-step explanation:

The formula to find the volume of a rectangular prism is l · w · h.

l = ?

w =  6 in

h = 5 in

We know the volume of the following figure is equal to 240 and so we can set up an equation where we solve for l (length).

l · 6 · 5 = 240

To get l by itself, you divide 240 by 6 and then by 5 to get your answer.

l = 8

We can check our work here by multiplying 8 · 6 · 5 which gives us the correct 240.

A particular type of cell increases by 75% in number every hour. Find the number of cells present at the end of 12 hours if there are initially 4 of these cells?

Answers

We have been given that a particular type of cell increases by 75% in number every hour. We are asked to find the number of cells present at the end of 12 hours if there are initially 4 of these cells.

We will use exponential growth formula to solve our given problem.

[tex]y=a\cdot (1+r)^x[/tex], where,

y = Final amount,

a = Initial amount,

r = Growth rate in decimal form,

x = Time.

[tex]75\%=\frac{75}{100}=0.75[/tex]

Upon substituting initial value [tex]a=4[/tex] and [tex]x=12[/tex] in above formula, we will get:

[tex]y=4\cdot (1+0.75)^{12}[/tex]

[tex]y=4\cdot (1.75)^{12}[/tex]

[tex]y=4\cdot 825.0050068497657776[/tex]

[tex]y=3300.020027[/tex]

[tex]y\approx 3300[/tex]

Therefore, there will be approximately 3300 cells at the end of 12 hours.

Step-by-step explanation:

The diameter of the circle is the distance from the endpoint to another endpoint. The diameter of the given circle is segment PQ. To determine the diameter of the circle, we would apply the formula for determining the distance between two points on a straight line is expressed as

Distance = √(x2 - x1)² + (y2 - y1)²

Therefore,

Diameter = √(1 - - 3)² + (9 - 5)²

Diameter = √4² + 4² = √32

Radius = diameter/2 = √32/2

A circle is the set of all points in a plane equidistant from a fixed point called the origin or center.

The center of the circle is determined by applying the midpoint formula

(x1 + x2)/2, (y1 + y2)/2

= (- 3 + 1)/2, (5 + 9)/2

Center = (- 1, 7)

The formula for determining the equation of a circle us expressed as

(x - h)² + (y - k)² = r²

Where

r represents the radius of the circle

h and k represents the x and y coordinates of the center of the circle. Comparing with the given points,

h = - 1 and k = 7

Substituting into the formula, it becomes

(x - h)² + (y - k)² = r²

(x - - 1)² + (y - 7)² = (√32/2)²

(x + 1)² + (y - 7)² = 32/4

(x + 1)² + (y - 7)² = 8

Step-by-step explanation:

its an isosceles triangle, as we can tell from the sides, that means that 2 angles are the same size as well. a triangle has 180 degrees.

180-38=142

142/2=71

check

71+71+38=180

that means x=71 degrees

hope this helps!!

Answer:

x = 71

Step-by-step explanation:

The triangle has 2 congruent sides and is isosceles.

Thus the 2 base angles are congruent, so

x = [tex]\frac{180-38}{2}[/tex] = [tex]\frac{142}{2}[/tex] = 71

How many boxes of fish can fit in the shipping box? Explain your answer, will give brainlest!

Answers

Answer:

2340 boxes

Step-by-step explanation:

to find out how many boxes or cans fit there u need to know the volume of the box and the cans or boxes

v= l*w*h

v= volume

l=length

w=width

h=height

first lets find the volume of one can or box of fish food

the length, the width, and the height are the same which is 1/4, so cube 1/4 or 1/4*1/4*1/4

1/4*1/4*1/4= 1/16 *1/4= 1/64

Now u have to find the volume of the shipping box, so the length is 3 3/4, the width is 3, and the height is 3 1/4

3 3/4*3*3 1/4= 15/4*3/1*13/4

15/4*3/1*13/4= 45/4*13/4 = 585/16

now divided the volume of shipping box by the volume of fish food boxes

585/16 divided by 1/64 and now u do the KFC or the keep flip change

u keep the 585/16 and then flip the sign to multiplication and then change the last number to 64/1

585/16 times 64/1= 37440/16 or 2340
