Answer:

B

Step-by-step explanation:

You can knock out A, because this isn't talking about temperature, and C and D are proven untrue by the data. The only one left is B, which if you check, is also consistant with the data.

Answer:

If we are assuming that plan A produces a whole gallon then you would need 15 parts white and 6 parts red

Step-by-step explanation:

Answer: C. [tex]B=\left[\begin{array}{ccc}1\\3\\-5\end{array}\right][/tex]

Step-by-step explanation: I got this right on Edmentum.

Several operations such as addition, subtraction, multiplication, etc. can be performed on matrices. The value of matrix B is:

[tex]B =\left[\begin{array}{c}1&3&-5\end{array}\right][/tex]

Given that:

[tex]A =\left[\begin{array}{ccc}2&4&-2\\4&-5&7\\2&7&5\end{array}\right][/tex]

[tex]AB =\left[\begin{array}{c}24&-46&-2\end{array}\right][/tex]

Let matrix B be:

[tex]B =\left[\begin{array}{c}a&b&c\end{array}\right][/tex]

The product of A and B is as follows:

[tex]\left[\begin{array}{ccc}2&4&-2\\4&-5&7\\2&7&5\end{array}\right] \times\left[\begin{array}{c}a&b&c\end{array}\right][/tex]

Multiply the rows of A to the column of B. So, we have:

[tex]AB =\left[\begin{array}{ccc}2a+4b-2c\\4a-5b+7c\\2a+7b+5c\end{array}\right][/tex]

This means that:

[tex]\left[\begin{array}{ccc}2a+4b-2c\\4a-5b+7c\\2a+7b+5c\end{array}\right] = \left[\begin{array}{c}24&-46&-2\end{array}\right][/tex]

By comparison, we have:

[tex]2a + 4b - 2c = 24[/tex] --- (1)

[tex]4a - 5b + 7c = -46[/tex] --- (2)

[tex]2a + 7b + 5c = -2[/tex] --- (3)

Multiply (1) and (3) by 2

[tex]2a + 4b - 2c = 24[/tex] --- (1)

[tex]4a + 8b - 4c = 48[/tex] ----- (5)

[tex]2a + 7b + 5c = -2[/tex] --- (3)

[tex]4a + 14b + 10c = -4[/tex] ---- (6)

So, we have:

[tex]4a - 5b + 7c = -46[/tex] --- (2)

[tex]4a + 8b - 4c = 48[/tex] ----- (5)

[tex]4a + 14b + 10c = -4[/tex] ---- (6)

Make 4a the subject in each of the equations

[tex]4a = -46 + 5b - 7c[/tex]

[tex]4a = 48 - 8b + 4c[/tex]

[tex]4a = -4 - 14b - 10c[/tex]

[tex]4a = 4a[/tex]. So, we have:

[tex]-46 + 5b - 7c = 48 - 8b + 4c[/tex]  and  [tex]-46 + 5b - 7c = -4 - 14b - 10c[/tex]

Simplify both expressions

[tex]-46 + 5b - 7c = 48 - 8b + 4c[/tex]

[tex]5b + 8b - 7c - 4c = 48 + 46[/tex]

[tex]13b - 11c = 94[/tex]

[tex]-46 + 5b - 7c = -4 - 14b - 10c[/tex]

[tex]5b+14b - 7c + 10c = 46-4[/tex]

[tex]19b + 3c = 42[/tex]

Make c the subject

[tex]c = \frac{42 -19b}{3}[/tex]

Substitute [tex]c = \frac{42 -19b}{3}[/tex] in [tex]13b - 11c = 94[/tex]

[tex]13b - 11 \times (\frac{42 - 19b}{3}) = 94[/tex]

Multiply through by 3

[tex]39b - 11 \times (42 - 19b) = 282[/tex]

Open bracket

[tex]39b - 462 + 209b = 282[/tex]

Collect like terms

[tex]39b + 209b = 282+462[/tex]

[tex]248b = 744[/tex]

Solve for b

[tex]b = \frac{744}{248}[/tex]

[tex]b = 3[/tex]

Solve for c

[tex]c = \frac{42 -19b}{3}[/tex]

[tex]c = \frac{42 - 19 \times 3}{3}[/tex]

[tex]c = \frac{-15}{3}[/tex]

[tex]c = -5[/tex]

Solve for a in [tex]4a = -4 - 14b - 10c[/tex]

[tex]4a = -4 - 14 \times 3 - 10 \times -5[/tex]

[tex]4a = 4[/tex]

Divide by 4

[tex]a = 1[/tex]

Recall that matrix B is:

[tex]B =\left[\begin{array}{c}a&b&c\end{array}\right][/tex]

Hence, the value of matrix B is:

[tex]B =\left[\begin{array}{c}1&3&-5\end{array}\right][/tex]

Answer:

Step-by-step explanation:

The question is not complete, here is the complete question

The annual growth rate r for an investment can be found using P=Po(1+rt), where is time in years, P is the present value, and P0 is the original investment. An investment of $4000 was made in 2005 and had a value of $7500 in 2010. What was the average growth rate of the investment?

Given

Po=$4000

P=$7500

time = 2010-2005= 5 years

rate r =?

Step two

7500=4000(1+r*5)

7500=4000+20000r

7500-4000=20000r

3500=20000r

divide both sides by 20000

r=3500/20000

r=0.175

% rate= 0.175*100

%rate= 17.5

Therefore the average growth rate is 17.5%

Answer:

B. $175.00

Step-by-step explanation:

Since the coupon is 30% off, to find how much it costs after the coupon, use the opposite: 70%

Which equals 0.7

Multiply that by 250:

250 × 0.7 = 175

So the answer will be $175.00

Step-by-step explanation:

Answer:

y = -8x + 3

Step-by-step explanation:

plug in the point and the slope into the slope intercept formula (y=mx+b)

the slope will be the same since you want the line to be parallel

11 = -8(-1) +b   now solve for b

11 = 8 + b

-8   -8

3 = b

now write the equation with only the slope and the y intercept

y = -8x + 3

The equation of a line that passes through (-1, 11) and is parallel to the line y = - 8x + c is y = - 8x + 3.

The slope intercept form of a line is given by -

y = mx + c

m is the slope of line

c is the y - intercept

Given is a line that passes through (-1, 11) and is parallel to the line -

y = − 8x − 2.

Since, the line is parallel to the line → y = − 8x − 2, therefore, their slope will be same and is equal to m = - 8.

Now, in the slope intercept form, assume that the equation of line looks like -

y = - 8x + c

Now, the line passes through the point (-1, 11), we can write -

11 = -8 x -1 + c

11 - 8 = c

c = 3

Hence, we can write the equation of the line as -

y = - 8x + 3

Therefore, the equation of a line that passes through (-1, 11) and is parallel to the line y = - 8x + c is y = - 8x + 3.

Approach-avoidance

Step-by-step explanation:

The term that is being described in this question is known as Approach-avoidance. This occurs in many real-life scenarios where individuals really want something until they are met with the negative side of that goal and ultimately turn away because of those negative traits. One example that is widely used for this term is marriage. Marriage in itself is a very positive goal that many individuals strive for, but ultimately push away from it when they begin to see the negative aspects of it, even if the positive values overshadow the negative ones.

The answer is 5/2

Step-by-step explanation:

5/6 times 3

15/6=

5/2

The fraction form of (5/6)×3 after simplification is  5/2.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, (5/6)×3.

= (5/6)×(3/1).

Now in fraction multiplication, we simply multiply the numerator with the numerator and the denominator with the denominator.

= (5×3)/(6×1).

= 15/6.

= 5/2.
