Answer:

The scientist stated her hypothesis, set up a controlled experiment, and isolated the variable that could affect her work.

Answer:

[tex]y=\displaystyle -\frac{1}{4}x+\displaystyle \frac{15}{4}[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept.

1) Determine the slope (m)

[tex]m=\displaystyle \frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

In the graph, two points are indicated: (-5,5) and (3,3). Plug these into the equation:

[tex]m=\displaystyle \frac{3-5}{3-(-5)}\\\\m=\displaystyle \frac{3-5}{3+5}\\\\m=\displaystyle \frac{-2}{8}\\\\m=\displaystyle \frac{-1}{4}[/tex]

Therefore, the slope of the line is [tex]\displaystyle -\frac{1}{4}[/tex]. Plug this into  [tex]y=mx+b[/tex]:

[tex]y=\displaystyle -\frac{1}{4}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=\displaystyle -\frac{1}{4}x+b[/tex]

Plug in one of the points we used earlier and solve for b:

[tex]3=\displaystyle -\frac{1}{4}(3)+b\\\\3=\displaystyle -\frac{3}{4}+b\\\\3+\displaystyle \frac{3}{4}=b\\\\\frac{15}{4} =b[/tex]

Therefore, [tex]\displaystyle \frac{15}{4}[/tex] is the y-intercept. Plug this back into [tex]y=\displaystyle -\frac{1}{4}x+b[/tex]:

[tex]y=\displaystyle -\frac{1}{4}x+\displaystyle \frac{15}{4}[/tex]

I hope this helps!

[tex]v = 2744 {m}^{3} [/tex]

Step-by-step explanation:

cube-shaped, 14m on each side.

volume...?

[tex]v = 14 \times 14 \times 14 [/tex]

[tex]v = {14}^{3} [/tex]

[tex]v = 2744 {m}^{3} [/tex]

The volume of the new monkey cage is  2744m^3

Let the three dimensions(height, length, width) be x, y,z units respectively.

Then the volume of the cuboid is given as

[tex]V = x \times y \times z \: \rm unit^3[/tex]

The formula for the volume of cuboid is V = s * s * s;

Where, s= side of the cage

s = 14 meters

V = 14 * 14 * 14

V = 2744 m^3

Therefore, the volume of cuboid will be 2744m^3

Answer:

-12.8

Step-by-step explanation:

Replace the letters with the respective values ( a = 4, b = 2, c = 3).

So (-3a+4b)^3 would become (-3 (4) + 4 (2))^3 = (-12 + 8)^3 = -4^3 = -64

And the bottom part (2c -1) would become (2 (3) - 1) = 6-1 = 5

So the final result would be -64 / 5 which is approximately -12,8

Answer:

x = -15/4

Step-by-step explanation:

1 - 4/3x = 1/2(-x + 7)

~Simplify

1 - 4/3x = -1/2x + 7/2

~Subtract 1 from both sides

-4/3x = -1/2x + 5/2

~Add 1/2x to both sides

-2/3x = 5/2

~Multiply -3/2 to both sids

x = -15/4

Answer:

Ratio of area = 16:25

Step-by-step explanation:

ar(ABC)/ar(DEF) = side²/side'²

16/25 = s²/s'²

√(16/25) = s/s'

4/5 = s/s'

Ratio of side are 4:5

Answer:

4

Step-by-step explanation:

To find the degree of a polynomial, identify the term with the greatest exponent. The exponent of that term is the degree of the polynomial.

In the given polynomial 5x⁴+4x²+2x+1​, the term with the greatest exponent is 5x⁴. This term has an exponent of 4, so therefore, the degree of the polynomial is 4.

In algebra, like terms are terms that have the same variables and powers. ... Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.

Answer:

These are not like terms.

Step-by-step explanation:

Although their variables are the same, the exponents are different.  LIke terms must have the same variables AND same exponents.  The first term's variables are: x raised to the second power times y, while the other term's variables are:  y times x times 2
