Step-by-step explanation:

Answer:

Step-by-step explanation:

The given equation assumes a 12 cubic inch initial volume.  The question wants to know when, in minutes, the volume, y, reaches 36 in^3:

y = 12*(2)^(t/60), where t is time in minutes

Therefore:

36 = 12*(2)^(t/60)

3 = (2)^(t/60)

log(3) =(60/t) log(2)

t = 60log(3)/log(2)

t = 95.1 minutes

Answer:

Equilateral triangles are always similar, whereas isosceles triangles are not necessarily comparable.

The angles in one triangle must have the same values as the angles in the other triangle for two triangles to be identical. The lengths of the sides must be proportional.

Both may be isosceles, however one may have 30°, 30°120° angles and the other may have 20°, 20° 140° angles.

As a result, isosceles triangles are not necessarily comparable.

Because equilateral triangles always have three angles of 60 degrees apiece, any

All equilateral triangles are always similar and isosceles triangles are not always similar.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

A) No, all isosceles triangles are not similar. An isosceles triangle is a triangle with two sides of equal length. For all isosceles triangles to be similar, it would have to be the case that the ratios comparing the lengths of corresponding sides of all isosceles triangles are the same.

B) Yes. All equiangular triangles are similar. In geometry, we have a nice theorem that allows us to determine if two triangles are similar using the measures of their corresponding angles.

All equilateral triangles are always similar. Similar triangles are always congruent.

Therefore, all equilateral triangles are always similar and isosceles triangles are not always similar.

Answer:

y = 17 - 4x or y = 17 + (-4x)

Step-by-step explanation:

Plug the slope (m) into the equation y=mx+b so it becomes y = -4x + b

Then see how much your line changed from the point to the y-axis. In this case, it changed by negative 12. So you have to go up 12 points to reach the y-intercept. (5+12=17)

Then, plug that number into the equation.

y = 17 - 4x

Answer:

98.9

Step-by-step explanation:

115 - 20% = 92
92 + 7.5% = 98.9

Answer:

the original price is 115 after we subtract 20% we are left with 92 so now

the price of the coffee table is 92 but with 7.5% as tax, the final price is $98.90 since 7.5% of 92 is 6.90

Answer:

Factors of 99: 1, 3, 9, 11, 33, and 99.

Answer:m<c=120

Step-by-step explanation:

You set the two expressions equal to each other solve for x and then plug in x to one expression to get the angle.

After that add the two angles together and subtract them from 360 divide by two and you’ll get the other two angles.

This usually only applies to parallelograms.

Step-by-step explanation:

3x² + 5x + 2 = 0

(a)

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 3 × 2 = 6 and sum = 5

The factors are + 3 and + 2

Use these factors to split the x- term

3x² + 3x + 2x + 2 = 0 ( factor the first/second and third/fourth terms )

3x(x + 1) + 2(x + 1) = 0 ← factor out (x + 1) from each term

(x + 1)(3x + 2) = 0

(b)

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

3x + 2 = 0 ⇒ 3x = - 2 ⇒ x = - [tex]\frac{2}{3}[/tex]

The three numbers are 12, 18 and 24

Arithmetic progression

Let the 3 number in arithmetic progression be:

a-d, d, a+d ...

If their sum is 3, then;

a-d+d+a+d = 3

2a + d = 3 ........... 1

If the sum of their squares is 11, then;

(a-d)² + d² + (a+d)² = 11

a²-2ad+d²+d²+a²+2ad+d²  11

2a²+3d² = 11 ....... 2

Solving the equations simultaneously, d = 6 and a = 12

First-term = 12

second term = 18

Thirs term = 24

Hence the three numbers are 12, 18 and 24

Answer:

-3, 1, -1 or -1, 1, 3

Step-by-step explanation:

We can create the equation of x + x+d + x+2d = 3 or use the sum formula to end up with x = 1-d.

We can then calculate d by using 11 and creating an equation like this.

x^2 + (x+d)^2 + (x+2d)^2 = 11 -> (1-d)^2 + (1)^2 + (1+d)^2 =11 which ends up with d equaling -2 or 2

If we plug d into the sum formula we get

(2x + 2 * 2)/2 *3 =3

and

(2x + 2 * -2)/2 *3 =3

This leaves us with starting terms -1 and 3. We can then finish the arithmetic sequence for each case by just using d.

Answer:

Step-by-step explanation:

For two lines to be parallel their slopes must be equal. For two lines to be perpendicular their slopes must be the negative reciprocal of each other.

Step 1 Find the slope of the equation.

Put it into the slope-intercept form. y = mx + b.  

For x-y = 7, move the x to the left; therefore subtract the x from both sides. this leaves you  -y = -x + 7

Then, divide both sides by -1 to get a positive y.  -y/-1 = (-x + 7)/-1

This leaves y = x - 7  The slope(m) for this equation is m = 1

The other equation must also have a slope of 1 or m=1 for the lines to be parallel.

Use the point given to you (-7, -6) and substitute for (x, y)

The slope-intercept form y = mx + b can once again be used.

x = -7, y =-6, and slope or m = 1

Therefore,  y = mx + b substituted will be -6 = (1)(-7) + b; now, solve for b which is the y intercept

-6 = -7 + b add 7 to both sides -6 +7 = -7 + b +7 ; therefore, b = 1

Now you know the slope(m) which is equal to 1 and the y-intercept(b) which is equal to 1.

Finally, substitute the m and b in the slope-intercept form

            y = (1)x + 1 or y = x +1
