To complete the table of values for y = x^2 - 4x, substitute the given values of x into the equation. To determine the matching graph, compare the shape, direction, and intercepts of the given curves to y = x^2 - 4x.

For part a), you need to substitute the given values of x into the equation y = x^2 - 4x to find the corresponding values of y.

So for x = 1, y = (1)^2 - 4(1) = 1 - 4 = -3.

For x = 2, y = (2)^2 - 4(2) = 4 - 8 = -4.

Similarly, you can find the values of y for the other given values of x.

For part b), look at the three curves drawn and find the one that matches the graph of y = x^2 - 4x. Compare the shape, direction, and intercepts of the graph to determine the correct curve.

∠XDQ : 41°

∠UXD: 139 °

Step-by-step explanation:

Allow me to rewrite your answer for a better understanding and please have a look at the attached photo.

A segment XD is drawn in rectangle QUAD as shown  below.

What are the measures of ∠XDQ and ∠UXD ?

My answer:

As we can see in the photo, ∠ADX = 49° and ∠ADU =90°

=>  ∠XDQ = ∠ADU - ∠ADX

= 90°  - 49°  = 41°

In the triangle ADX, we can find out the angle of ∠DXA

= 180° - ∠DAX - ∠ADX

= 180° - 90° - 49°

= 41°

=> ∠UXD = 180° - ∠DXA  (Because UA is a straight line)

=180° - 41°  

= 139 °

Answer:

Step-by-step explanation:

So, it's hard to know if the sides on the parallelogram are equal or not, but both a rhombus and square have four congruent sides, but only a square has four right angles.

So 1/2 shapes fit both parameters. Therefore there is a 50% probability it has four right angles, given that it has four congruent sides.

Answer:

The arrow is at a height of 48 ft after approximately 0.55 s  and after 5.45 s​

Step-by-step explanation:

The following information is missing:

The height of an arrow shot upward can be given by the formula s = v0*t - 16*t², where v0 is the initial velocity and t is time.How long does it take for the arrow to reach a height of 48 ft if it has an initial velocity of 96 ft/s?

If the arrow is at a height of 48 ft and its initial velocity is 96 ft/s, then:

48 = 96*t - 16*t²

16*t² - 96*t + 48 = 0

16*(t² - 6*t + 3) = 0

t² - 6*t + 3 = 0

t² - 6*t + 3 + 6 = 0 + 6

t² - 6*t + 9 = 6

(t - 3)² = 6

t - 3 = √6

t - 3 = 2.45; t = 2.45 + 3; t = 5.45

or

t - 3 = -2.45; t = -2.45 + 3; t = 0.55

Step-by-step explanation:

The solution to the system is where the two lines cross

x = -5

y = 2

Answer:

Option A, (-5, 2)

Step-by-step explanation:

Step 1:  Determine the solution

The solution is where both of the lines intersect.  In this graph, they intersect at the x-value -5 and at a y-value of 2.

Answer:  Option A, (-5, 2)

Answer:

Total = Principal * e ^ (rate * years)

Total = 17,183 * 2.718281828459 ^ (.054 * years)

After 1 year = 18,136.39

After 2 years = 19,142.68

After 5 years = 22,509.12

After 10 years = 29,486.15

We'll use this formula to find the doubling time:

Years = ln (total / principal) / rate

we'll use 200 for total and 100 for principal

Years = ln (200 / 100) / rate

Years = ln (2) / .054

Years = 0.69314718056 / .054

Years = 12.8360588993  Years Doubling Time

Step-by-step explanation:

The question is about continuous compound interest. An initial amount of $17,183 is invested with a 5.4% annual interest rate. An exponential function depicts the amount over time, you find the balance by substituting the values of time into the function, and the doubling time is calculated to be approximately 12.8 years.

The subject matter of this question deals with the concept of continuous compound interest in Mathematics. No additional deposits are made, only the principal amount is growing over time at a continuous compound interest. The formula for the balance in a continuously compounding account is given by P(t) = P0*e^(rt), where P0=initial balance, r=annual interest rate (as a decimal), t=time in years, and e=approximately 2.71828. In this case, P0 = $17,183 and r = 5.4% = 0.054.

a) The exponential function that describes the amount in the account after time t is: P(t) = $17,183*e^(0.054t)

b) Using this function, you can substitute the values of t to find the balance after each year, for example, for 1 year, it's P(1) = $17,183*e^(0.054*1) and similarly for 2, 5, and 10 years.

c) Doubling time can be obtained by equating P(t) = 2 * P0, which can be solved to obtain t = ln(2) / r (natural logarithm of 2 divided by the annual interest rate). Hence, it would approximately be 12.8 years.

Reflection of an L-shaped object with respect to the y-axis is a horizontal flip resulting in a mirror image with opposite signs

When an L-shaped object is reflected with respect to the y-axis,

It means that every point on the object is reflected across the line that divides the object into two halves, with each half on either side of the y-axis.

This reflection results in the object being flipped horizontally.

The new orientation of the object is a mirror image of the original but with opposite signs.

The reflection of an L-shaped object with respect to the y-axis is an important concept in geometry and is often used in practical applications such as graphic design and architecture.

So the reflection of Figure A in the y-axis is A' which is attached below.

Step-by-step explanation:

The midsegment of a trapezoid is calculated as

[tex]\frac{sumofbases}{2}[/tex] = [tex]\frac{16+24}{2}[/tex] = [tex]\frac{40}{2}[/tex] = 20

Final answer:

The length of the mid-segment of a trapezoid with bases of length 16 and 24 is 20 units.

Explanation:

The length of the mid-segment of a trapezoid is the average of the lengths of the two bases. To calculate it, you add the lengths of the bases and then divide by 2. Since the bases of the trapezoid in question have lengths of 16 and 24, you would perform the following calculation:

(16 + 24) / 2 = 40 / 2 = 20

Therefore, the length of the mid-segment is 20 units.

Answer:

The last bit is correct, a2 + b2 = c2 for all right triangles? You do not divide the measurements you can only add up the squares to find the square of the hypotenuse as the sum, and then square root the totaled squares back to a new number. It does not cover the area like the statement said so only the question is true as Pythagoras theorem can be used to find a missing side or to find the missing hypotenuse.

Step-by-step explanation:

Is this a valid geometrical proof that a2 + b2 = c2 for all right triangles?

Answer yes but only for c2 if we area adding.

This is because if we were looking and missing for a smaller side to the triangle measure and was already given the hypotenuse as one measure, then we can subtract either given alternative side would be; c2 - b2 = a2 to find an alternative side we subtract.

and c2- b2 = a2 works the same as c2 -a2 = b2.

None of the above formula finds the area, for the area we would need to multiply to find the height.

A = 1/2 x a x b

We have a different understanding to area

The area of a triangle is 1/2 given by the equation:

AΔ=(1/2)∗(base)∗(height) which is the smae as A= 1/2 x a x b

Eg)

Given: Measurements of A + B In attachment picture.

A = 3 cm

B = 4 cm

What is the area of the right triangle ABC?

Since the base leg of the given triangle is 4 cm, while the height is 3 cm, this gives:

AΔ=(1/2)∗3∗4=6cm2

So to find area we multiply A by 1/2 and multiply that product by the length of B (base).

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

To find the surface area of a rectangular prism, we need to calculate the area of each of its six faces and add them together.

The formula for the surface area of a rectangular prism is:

Surface area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

Substituting the given values, we have:

Surface area = 2(15 x 4) + 2(15 x 25) + 2(4 x 25)

Surface area = 30 + 750 + 200

Surface area = 980 square units

Answer: 26

Step-by-step explanation: Here, we have the expression 7s + 5 and we want to evaluate the expression when s is equal to 3.

To evaluate an expression, we simply plug the value

of the variable into the expression and solve.

So here, since s is equal to 3,

we have 7(3) + 5.

Notice that I used parentheses around the 3. It's always a good idea to use parentheses when substituting/plugging in numbers for variables.

Solving from here, 7(3) is equal to 21.

So we have 21 + 5 which is equal to 26.

So the value of our expression

when s is equal to 3 is 26.
