Matt is correct. The expression has no solution.

Algebraic expressions are known as expressions of numbers using letters or alphabets without their actual values.

They are composed of integer constants, variables, and the algebraic operations such as addition, subtraction, division and others

From the expression given, we have that;

8(x-5)=8x+40

First, let's expand the bracket

8x - 40 = 8x + 40

collect like terms

8x - 8x = 40 + 40

0 = 80

We can see that the expression does not have a solution as 'x' the variable was 0.

Thus, Matt is correct. The expression has no solution.

Step-by-step explanation:

The height of water in the tank in feet after t seconds can be expressed as h(t) = H - (Aw/Ah) 2gh t2, where Aw and Ah are the cross-sectional areas of the water and the hole in square feet respectively,

and g is the gravitational acceleration (32 ft/s2). The interval of definition for h(t) is 0 ≤ t ≤ H/2gh.

The graph of h(t) is a parabola with its vertex at (H/2gh, H) and is symmetric about the line t = H/2gh. It starts at (0, H) and gradually decreases to (H/2gh, 0).

Given the tank is 11 ft high, has radius 2 ft and the circular hole has radius in, and it is initially full, the time it will take to empty can be calculated as: t = √(2H/gAh) = √(22/(32 x π(0.52))) = 3.87 seconds. Therefore, it will take approximately 3.87 seconds to empty.

Answer:

The error is in Step 3:

She should have calculated the interquartile range as,

Chemistry = 85 - 60 = 25

Biology = 80 - 60 = 20

Step-by-step explanation:

*In a box plot, the median is the point on the number line where a line divides the rectangular box.

Thus, from the information given in the question about the box plots, the median for Chemistry = 80 (this is where a line divides the box)

Median for Biology = 70

The difference in the median = 80 - 70 = 10.

*Lauren didn't make any mistake in Step 1 and 2, as he equally got the same values.

==>The interquartile range in a box plot is simply the difference in the ranges (Q3 - Q1).

From the given information, the interquartile range for Chemistry = 85 - 60 = 25 (this is the difference in the ranges of the box)

Interquartile range for Biology = 80 - 60 = 20

The difference in interquartile range = 25 - 20 = 5

*Lauren made an error in Step 3 when calculating the interquartile range for both Chemistry and Biology, even though he arrive at the same value of the difference in the interquartile range we got as calculated above.

Answer:

\(m\angle L = 100^{\circ}\).

\(m\angle J = 80^{\circ}\).

\(m\angle M = 100^{\circ}\).

Step-by-step explanation:

Since segment \(JM\) is parallel to segment \(KL\), quadrilateral \(JKLM\) is a trapezoid.

Segment \(JK\) and segment \(LM\) (the two legs of this trapezoid) are equal in length. Hence, trapezoid \(JKLM\) would be an isoscele trapezoid. By symmetry, \(m\angle L = m \angle K = 100^{\circ}\).

Line \(JK\) traverses line \(JM\) and line \(KL\). \(\angle J\) and \(\angle K\) are a pair of consecutive interior angles as they are both between \(JM\!\) and \(KL\!\) and are on the same side of the traversal, \(JK\!\).

Since line \(JM\) is parallel to line \(KL\), any pair of consecutive interior angles between these two lines would add up to \(180^{\circ}\) (supplementary angles.) Thus, \(\angle J\) and \(\angle K\) are supplementary angles; \(m\angle J + m\angle K = 180^{\circ}\).

Since \(m\angle K = 100^{\circ}\), \(m\angle J = 180^{\circ} - m\angle K = 180^{\circ} - 100^{\circ} = 80^{\circ}\).

Answer: To find the equation of a line passing through two points, we can use the point-slope form of the equation:

y - y1 = m(x - x1)

where (x1, y1) are the coordinates of one of the points, and m is the slope of the line.

To find the slope, we can use the formula:

m = (y2 - y1)/(x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

So, let's plug in the values we have:

m = (-8 - 3)/(-8 - (-10)) = (-8 - 3)/2 = -11/2

Now we can use either point to find the equation. Let's use (-10, 3):

y - 3 = (-11/2)(x - (-10))

y - 3 = (-11/2)x - 55/2

y = (-11/2)x - 49/2

So the equation of the line through (-10, 3) and (-8, -8) is:

y = (-11/2)x - 49/2.

Answer:

-8

Step-by-step explanation:

It would be -2+2(-3)

Which means -2 plus 2 times -3

According to PEMDAS you have to do parenthesis first so 2 times -3 is -6 +-2=-8

So the answer is -8

Answer:

it would be -2 + 2(-3)

Step-by-step explanation:

the numbers given would replace the variables, so x would become -2 since its -x, and y would be (-3) in parenthesis since its to be multiplied (i believe if im remembering correctly) therefore it would become:

-2 + 2(-3)

Answer:

The n-values in this equation are called the coefficients.

Answer:

The equation is y = -2x + 6.

Step-by-step explanation:

Given that the slope-form equation is y = mx + b and the gradient is -2. So you have to find the value of b by substituting the coordinates into the equation :

\(y = mx + b\)

\(let \: m = - 2,x = 4,y = - 2\)

\( - 2 = - 2(4) + b\)

\( - 2 = - 8 + b\)

\(b = 6\)

\(y = - 2x + 6\)

Recall that the ratio 9:8 can be written as follows:

Answer: 72.

Answer:

72

Step-by-step explanation:

Since X : 64 = 9 : 8

Then we know X/64 = 9/8

Multiplying both sides by 64 cancels on the left64 × (X/64) = (9/8) × 64

X = (9/8) × 64Then solving for X X = 64 × (9/8)X = 72

Answer:

1.44

Step-by-step explanation:

To find the critical value Zα/2 for a 88% confidence level, we need to first find α/2.

α/2 = (1-0.88)/2 = 0.06/2 = 0.03

Using a Z-table or calculator, we can find the Z-score that corresponds to a cumulative probability of 0.03 from the left tail, which is -1.44.

Therefore, the critical value Zα/2 for a 88% confidence level is 1.44 (positive or negative depending on the direction of the test).

The position value, r(t) is equals to the (t³/6)k + 2j and velocity value, v(t) is equals to ( t²/2 )k + 4i , for a(t) = tk, v(0) = 4i, r(0) = 2j.

Acceleration is defined as the rate of change of the velocity of an object with respect to time. Accelerations are vector quanty.

a = dv/dt

We have the following informations are available,

Initial velocity, v(0) = 4i

Initial position, r(0) = 2j

Acceleration at any time "t",

a(t) = tk

we have to determine the value of v(t) and r(t).

As we know, a(t) = dv(t)/dt = tk

integrating the above equation ,

v(t) = ∫tk dt = ( t²/2 )k + c

at t = 0 , v(0) = 0 + c = 4i ( since, v(0) = 4i

=> c = 4i

So, v(t) = ( t²/2 )k + 4i

Also, velocity is calculated by derivative of postion (r) with respect to time.

=> v(t) = dr(t) /dt

=> r(t) = ∫ v(t) dt

=> r(t) = ∫ ( t²/2 )k dt

integrating value of the right hand side,

r(t) = ( t³/2×3 )k +d

= (t³/6)k + d

At t = 0, r(0) = (0/6)k + d

=> r(0) = d = 2j

so, r(t) = (t³/6)k + 2j

Hence, the required position and velocity are

(t³/6)k + 2j and ( t²/2 )k + 4i.

The return on the market portfolio is approximately 10.4%.

Suppose the risk-free return is 3%. The beta of a managed portfolio is 1.75. To calculate the return on the market portfolio using Jensen's measure, we can use the Capital Asset Pricing Model (CAPM) formula:

Expected Return = Risk-Free Return + Beta * (Market Return - Risk-Free Return)

Given that the alpha is 0% and the average return is 16%, we can rewrite the formula:

16% = 3% + 1.75 * (Market Return - 3%)

Now, we solve for the Market Return:

13% = 1.75 * (Market Return - 3%)

13/1.75 = Market Return - 3

7.43 ≈ Market Return - 3

Market Return ≈ 10.43%

So, the return on the market portfolio is approximately 10.4%.
