which trig function would you use?

Answer:

Step-by-step explanation:

(1/4)^3=1^3/4^3=1/64

Here we need to use the exponent property:

[tex](\frac{a}{b} )^n = \frac{a^n}{b^n}[/tex]

Using this, we will see that the given expression is equal to:

[tex]\frac{1}{64}[/tex]

We start with:

[tex](\frac{1}{4} )^3[/tex]

Now we can use the above property to rewrite this as:

[tex](\frac{1}{4} )^3 = \frac{1^3}{4^3}[/tex]

Now we know that:

1^3 = 1

4^3 = 4×4×4 = 16×4 = 64

Now we can replace these in the above expression to get:

[tex](\frac{1}{4} )^3 = \frac{1}{64}[/tex]

Answer:

4%

Step-by-step explanation:

Actual length of wire = 5 cm

The measured length of wire = 5.2 cm

We need to find the percent error in the measurement of the length of wire. It can be calculated as follows :

[tex]\%=\dfrac{\text{measured length-actiual length}}{\text{actual length}}\times 100\\\\=\dfrac{5.2-5}{5}\times 100\\\\=4\%[/tex]

So, the required percent error is 4%.

Answer and Step-by-step explanation:

We are given:

[tex]\frac{2y-1}{-3} = 5[/tex]

First, we multiply both sides by -3.

2y - 1 = 15

Now we add 1 to both sides.

2y = 16

Finally, we divide by 2 to each side.

y = 8

We are given:

2x + 30 = -4(5x -2)

First we distribute the -4 to 5x and -2.

2x + 30 = -20x + 8

Now we subtract 8 from both sides.

2x + 22 = -20x

Now we subtract 2x from both sides.

22 = -22x

Finally, we divide by -22 to both sides.

-1 = x

#teamtrees #WAP (Water And Plant)

Answer: Zeke will catch up with Niko at 16 yards from the start line, y = 16 yards.

Zeke will catch up Niko after 8 seconds, x = 8 seconds.

Step-by-step explanation: i) distance to be run = 30 yards

ii) Niko has a head start of 12 yards.

iii) speed of Zeke = 2 yards / second

iv) speed of Niko = 1 yard every 2 seconds = 0.5 yard / second

v) x represents the number of seconds they have been racing.

vi) y represents the distance from the start line.

vii) the time at which Zeke catches up with Niko will be given by

Therefore 2y - 24 = 0.5y 1.5 y = 24 y = 24 / 1.5 = 16 yards

Therefore x = 16 /2 = 8 seconds

Answer: D

Step-by-step explanation: asking for the difference

Answer:

The equation representing the left table is:  

y = 1.5x – 6

The equation representing the right table is:  

y = –4x + 6.1

The solution to the system of equations is:  

(2.2, –2.7)

Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The first table is

x            y

0           -6

1            -4.5

2            -3

3             -1.5

Slope = -4.5+6/1

=1.5

Now let us find y intercept

-6=1.5(0)+b

-6=b

So the equation representing the left table is y=1.5x-6

Now let us find second table

x            y

0           6.1

1             2.1

2           -1.9

3            -5.9

m=2.1-6.1/1=-4

Now y intercept

2.1=-4+b

b=2.1+4

b=6.1

Equation representing the right table is y=-4x+6.1

Now equate two equations

1.5x-6=-4x+6.1

1.5x+4x=6.1+6

5.5x=12.1

x=12.1/5.5

x=2.2

and y=-4(2.2)+6.1

y=-8.8+6.1

y=-2.7

Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

Step-by-step explanation:

The formula to find the volume of a sphere is  (4/3) · π · r3 So~

V=(4/3) · π · r3 = (4/3) · π · 3^3 ≈ 113.09734

Answer: -4

Step-by-step explanation:

If you are given a problem like this with two points, the easiest way to find the slope is using the equation [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex] with points [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex].

In this problem, by looking at the graph, you can identify the points (0, 10) and (5, -10)

Let's label these numbers:

Now, plug these numbers into the formula above. That gives you [tex]\frac{-10-10}{5-0}[/tex].

-10 - 10 = -20 and 5 - 0 = 5, which gives you a fraction of [tex]\frac{-20}{5}[/tex], which can be simplified down to -4.
