Answer:

See attachment for graph

Step-by-step explanation:

Given

[tex]y = x -4[/tex]

The intercepts

For y intercept, we have: [tex]x =0[/tex]

[tex]y = x -4[/tex]

[tex]y = 0 - 4[/tex]

[tex]y = - 4[/tex]

For y intercept; we have: [tex]y = 0[/tex]

[tex]y = x -4[/tex]

[tex]0 = x - 4[/tex]

[tex]x = 4[/tex]

So, the intercepts are: (0,-4) and (4,0)

Answer:

y = -2/3 x +2

Step-by-step explanation:

2x+3y = 12

First find the slope by putting it in slope intercept form y= mx+b where m is the slope and b is the y intercept

Subtract 2x from each side

3y = -2x+12

Divide by 3

3y/3 = -2/3x +12/-3

y = -2/3x -4

The slope is -2/3

Parallel lines have the same slope

The only line with the same slope is y = -2/3 x +2

The only line

Answer:

a)  [tex]F=0.16Hz[/tex]

b)  [tex]\omega=1rad/s[/tex]

c)  [tex]L=9.54m[/tex]

d)  [tex]g=9.46m/s^2[/tex]

Step-by-step explanation:

From the question we are told that:

Time [tex]T =6.2[/tex]

a)

Generally the equation for Frequency F is mathematically given by:

 [tex]F=\frac{1}{T}[/tex]

 [tex]F=\frac{1}{6.2}[/tex]

 [tex]F=0.16Hz[/tex]

b)

Generally the equation for Frequency F is mathematically given by:

 [tex]\omega=2\pi f[/tex]

 [tex]\omega=2*314* 0.16[/tex]

 [tex]\omega=1rad/s[/tex]

c)

Generally the equation for Length of Chandelier L is mathematically given by:

Since

 [tex]T=2*3.142\sqrt{\frac{L}{g}}[/tex]

Therefore

 [tex]L=\frac{gT^2}{4 \pi^2}[/tex]

 [tex]L=\frac{9.8*(6.2)^2}{4 \pi^2}[/tex]

 [tex]L=9.54m[/tex]

d)

Since

Michelson exhibit except this one swings back and forth 0.11 seconds slower

Therefore

 [tex]T'=T+0.11[/tex]

 [tex]T'=6.31[/tex]

Generally the equation for acceleration due to gravity g is mathematically given by:

 [tex]g = \frac{4\pi ^2L}{( T')}^2[/tex]

 [tex]g = \frac{4\pi ^2L\*9.54}{( 6.31 s )}^2[/tex]

 [tex]g=9.46m/s^2[/tex]

Answer:

y = 2

Step-by-step explanation:

y = |x| - 5

|?| means an absolute value of a number

in this case x = -7 so the absolute value for -7 would be 7

y = 7 - 5

y = 2

Answer:

The warranty period should be of 35 months.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Cook-Easy blender has a mean time before failure of 41 months with a standard deviation of 4 months

This means that [tex]\mu = 41, \sigma = 4[/tex]

What should be the warranty period, in months, so that the manufacturer will not have more than 8% of the blenders returned?

The warranty period should be the 8th percentile, which is X when Z has a p-value of 0.08, so X when Z = -1.405.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.405 = \frac{X - 41}{4}[/tex]

[tex]X - 41 = -1.405*4[/tex]

[tex]X = 35.4[/tex]

Rounding to the nearest integer, 35.

The warranty period should be of 35 months.

Answer:

  9c² -4p²

Step-by-step explanation:

The product of a sum and difference of the same two terms is the difference of their squares:

  (3c +2p)(3c -2p) = 3c(3c -2p) +2p(3c -2p)

  = (3c)² -6cp +6cp -(2p)²

  = (3c)² -(2p)² = 9c² -4p²

Answer:

option A, C, D and F are mathematical sentences.

Answer:

The answer would be a) 4-2g

Step-by-step explanation:

Multiplying by one half is like dividing by 2!

8/2 = 4

and

4/2 = 2

It can't be b because you can't add 4g+2

It can't be c because you can't completely remove the 8/4

It can't be d because you didn't actually distribute

Answer:

$1689

Step-by-step explanation:

Excess of rent amount over annual property tax bill = annual rent - annual property tax

annual property tax =  [(assessed property value / 100) x 1.69]

( $390,000 / 100) x 1.69 = $6591

Annual rent = $690 x 12 = $8280

$8280 - $6591 = $1689

Answer:

Adjacent, b = 45 units

Step-by-step explanation:

Let the length of sides of the triangle be;

Given the following data;

Hypotenuse, c = 53 units

Opposite, a = 28 units

To find the missing side (adjacent), we would have to apply Pythagorean' theorem.

From Pythagorean theorem;

c² = a² + b²

Substituting into the formula, we have;

53² = 28² + b²

2809 = 784 + b²

Rearranging the equation (collecting like terms), we have;

b² = 2809 - 784

b² = 2025

Taking the square root of both sides, we have;

b = √2025

Adjacent, b = 45 units

Answer:

12

Step-by-step explanation:

because you replace  8 with 3

Answer:

40 cm

Step-by-step explanation:

57600 is the volume here

Because "was filled with 57600cm of water."

36 x 40 x n = 57600

n = 40

Answer:

9 = h

Step-by-step explanation:

The formula of finding the volume of a pyramid is:

V = l * w(h / 3)

We know that Volume is 36, base or Length is 4 and the Width is 3, therefore;

36 = 4 * 3 (h/3)

36 = 12 * h/3

36/12 = h/3

3 = h/3

3(3) = h

9 = h

Therefore the height or h of the pyramid is 9cm

Answer:

[tex] {x}^{2} - {y}^{2} [/tex]

difference of two squares:

[tex](x + y)(x - y)[/tex]

Answer: Both x and y are [tex]\frac{\sqrt{2}}{2}[/tex] which is the same as [tex]\frac{1}{\sqrt{2}}[/tex]

In other words, the point [tex]\left( \frac{\sqrt{2}}{2}, \frac{\sqrt{2}}{2} \right)[/tex] is on the unit circle for the angle pi/4 radians. This point is equivalent to [tex]\left( \frac{1}{\sqrt{2}}, \frac{1}{\sqrt{2}}\right)[/tex]

==============================================

Explanation:

The angle pi/4 radians is equivalent to 45 degrees. Draw out a 45-45-90 triangle with hypotenuse 1, and you'll find the congruent legs are each [tex]\frac{1}{\sqrt{2}}[/tex] units long (apply the pythagorean theorem). If you apply the sine and cosine ratios, you'll get the answer shown above.

Recall that

and also

The pythagorean theorem is a^2+b^2 = c^2.
