Answer:

Question 1: [tex]x=4[/tex]

Question 2: [tex]x= \pm7[/tex]

Question 5: The dimensions of one face of the container are 6 by 6 inches.

Step-by-step explanation:

Hi there!

Question 1

[tex]x^3=64[/tex]

Rewrite 64 as a power of 3:

[tex]x^3=4^3[/tex]

(We could find that 4³ = 64 through trial and error)

This above equation makes it true that x=4. If aⁿ = bⁿ, then a=b:

[tex]x=4[/tex]

Question 2

[tex]x^2=49[/tex]

Rewrite 49 as a power of 2:

[tex]x^2=7^2[/tex]

Again, we could have found this through trial and error, or by looking at our multiplication tables.

[tex]x=7[/tex]

However, remember that positive and negative numbers will all square to be a positive number. So, therefore, x can be -7 OR 7 (since both, when squared, equal 49):

[tex]x= \pm7[/tex]

Question 5

Let x be equal to the length of one edge of the cube.

Volume of a cube formula: [tex]V=x^3[/tex]

Plug in the given information, when V is the volume:

[tex]216=x^3[/tex]

Rewrite 216 as a power of 3:

[tex]6^3=x^3[/tex]

^ We could have found this through trial and error.

[tex]x=6[/tex]

Therefore, the dimensions of one face of the container are 6 by 6 inches.

I hope this helps!

It will make it 70 miles because it leaks 4 ounces every minute so divide 480 by 4 and get 120 with would be for how many minutes you would be able to drive with the leak. So convert minutes to hours and you get 2 hours and every hour you go 35 miles so multiply 35 by 2 and you get 70.

Answer:

3 kids, 4 Adults

Step-by-step explanation:

x = kids

y = adults

Total = 7

x + y = 7

y = x + 1

do a bit of solvin, too much to type lol

2x = 6

x = 3

And since X = 3  and Y = X + 1

Y = 3 + 1 = 4

Answer:

y = 3

Step-by-step explanation:

It has to be parallel to the x axis

the coordinates to the point is (6,3)

so to be parallel to x-axis y must always be 3 in this question

so y = 3 is the answer

Have a nice day! :-)

Answer:

f(2) = -2

Step-by-step explanation:

plug in 2 to wherever x is in this statement:

f(2) = -2(2^2) - 2(2) + 10

f(2) = -2(4) - 4 + 10

f(2) = -8 - 4 + 10

f(2) = -2

Answer:

65  

Step-by-step explanation:

45, 50, 52, 58, 62, 68, 72, 78, 81, 95  

62 + 68 = 130/2 = 65  

The median is 65

The median of the weight of the male dogs is M = 65 lb

The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values. The steps for finding the median differ depending on whether you have an odd or an even number of data points

Arrange the data points from smallest to largest.

If the number of data points is odd, the median is the middle data point in the list.

If the number of data points is even, the median is the average of the two middle data points in the list.

Given data ,

Let the weights of the male dogs be represented as set A

where the value of A is

Set A = { 45, 50, 52, 58, 62, 68, 72, 78, 81, 95 }

On simplifying , we get

The number of terms = 10

So , the median M = ( 62 + 68 ) / 2

The median M = 130/2 = 65 lb

where the mean is C = 66.1 lb

Hence , the median is M = 65 lb

Answer:

1.2

Step-by-step explanation:

1. First, we have to write an equation with a variable! Given 0.8%, we know that it's equal to (0.8/100), and "of" means to multiply. Therefore, the equation will looks like this: [tex]\frac{0.8}{100} * 150 = x[/tex]

2. Now, let's solve for x!

Therefore, 0.8% of 150 is 1.2!

Answer:

25 = units Jose travelled

Jh to Th = x moves 12 across  

and y moves 0 is constant (up/down or constant)

Th to FF = x moves 0 stays constant and y moves 13 left

12 + 13 = 25

The purpose of this exercise is concerning parabolas = curve equations

x has two points x = -6 and x = 6

y has two points y = -5 and y = 8

however we cant plot this as ANSWER without using all the coordinates

y has one answer unit at 13 and not shown in an equation if it was the y intercept or curve mid point it would be a straight line and not a curve at 13 we can therefore set y to zero 0 as mid point curve when drawing the curve.

Then to find the each unit change we could prove with straight line upon the parabola by first using the straight line equation formula y-y1 = m(x+x1)

Straight line equation

Plug in Jose's coordinates given in the question.

Therefore y - - 6 = 6 (x + 8 ) = y+6 = 6x + 46  multiply out

= y+6 = 6x + 46 -6 cancel out with -6

= y = 6x+40

the answer therefore becomes  y=6x+40

Plug in the same for Tyrell coordinates given in the question.

y - 6 = -6 (x + 8 ) = y-6 = -6x + 46  multiply out

= y-6 = -6x - 46 + 6 cancel out with +6

= y = -6x+52

and is a decrease of 6 i various ways.  

Plug in for Football field coordinates given in the question.

y-6 = -6(x -5)

= y -6 = -6x +30

= y = -6x + 30+6

= y = -6x + 36

Shows constant 6 and -6 for m the slope and 46-36 = 10 decrease each side from 0 being the curve mid point on x line. down into the mid curve |

= 10+10 to represent each side = 20 then +5 = 25

As the shift in the curve makes negative positive and positive negative.

= 25 units

2x + 3y = 1470

3y = -2x + 1470

y = -2/3x + 490 is the equation in slope intercept form.  

slope = -2/3

y intercept = 490

0

52 Remainder

Step-by-step explanation:

The value of [tex]c[/tex] such that the line [tex]y = 2\cdot x + 3[/tex] is tangent to the parabola [tex]y = c\cdot x^{2}[/tex] is [tex]-\frac{1}{3}[/tex].

If [tex]y = 2\cdot x + 3[/tex] is a line tangent to the parabola [tex]y = c\cdot x^{2}[/tex], then we must observe the following condition, that is, the slope of the line is equal to the first derivative of the parabola:

[tex]2\cdot c \cdot x = 2[/tex] (1)

Then, we have the following system of equations:

[tex]y = 2\cdot x + 3[/tex] (1)

[tex]y = c\cdot x^{2}[/tex] (2)

[tex]c\cdot x = 1[/tex] (3)

Whose solution is shown below:

By (3):

[tex]c =\frac{1}{x}[/tex]

(3) in (2):

[tex]y = x[/tex] (4)

(4) in (1):

[tex]y = -3[/tex]

[tex]x = -3[/tex]

[tex]c = -\frac{1}{3}[/tex]

The value of [tex]c[/tex] such that the line [tex]y = 2\cdot x + 3[/tex] is tangent to the parabola [tex]y = c\cdot x^{2}[/tex] is [tex]-\frac{1}{3}[/tex].
