Answer:

QU is 21, and I *think* that VS would be 8.5.

Answer:

QV = 21 , VS = 8.5

Step-by-step explanation:

QU and RS are medians of Δ PQR

the point V where the medians intersect is the centroid.

on each median the distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint.

then

VU = [tex]\frac{1}{2}[/tex] QV = [tex]\frac{1}{2}[/tex] × 14 = 7

so

QU = QV + VU = 14 + 7 = 21

and

VS = [tex]\frac{1}{2}[/tex] RV = [tex]\frac{1}{2}[/tex] × 17 = 8.5

4) Let the polynomial function of degree 4 that has roots 3, 2, 2+ i as its roots be p(x).

So, the required polynomial function is:

p(x)=(x−3)(x−2)(x−(2+i))(x−(2−i))

= (x−3)(x−2)(x^2−(2+i)x−(2−i)x+(2−i)(2+i))

= (x−3)(x−2)(x^2−2x−ix+ix+4)

= (x−3)(x−2)(x^2−2x+4)

= x^4−9x^3+28x^2−36x+24

Thus, the polynomial function of degree 4 that has real coefficients and has 3, 2 and 2+ i as some of its roots is x^4−9x^3+28x^2−36x+24.

Given: x^3−2x^2+36x−72=0 and 6i is a zero of this polynomial function.

So, we can write it as:

x^3−2x^2+36x−72= (x−6i)(x−(−6i))(x−6)

= (x−6i)(x+6i)(x−6)

As this polynomial function has real coefficients, so the imaginary roots occur in conjugate pairs.

Thus, the remaining zeros are:

−6i (as 6i is a zero, so −6i is also a zero due to conjugate pair of complex roots) and 6 (as 6i is one factor of the polynomial function, so x−6i will be its conjugate factor, which will be x+6i. And, the remaining factor will be x−6)

Therefore, the remaining zeros of x^3−2x^2+36x−72 polynomial function are −6i and 6.

Answer:

Step-by-step explanation:

a. To find the area of the sector, we can use the formula:

A = (θ/360)πr^2

where A is the area of the sector, θ is the central angle in degrees, r is the radius of the circle, and π is the constant pi.

In this case, the radius is 4 cm and the central angle is 45 degrees. Substituting these values into the formula, we get:

A = (45/360)π(4^2)

A = (1/8)π(16)

A = 2π

Therefore, the area of the sector is 2π square cm.

b. To find the area of the segment of a circle, we need to subtract the area of the triangle formed by the two radii and the chord from the area of the sector.

The central angle of the sector is 45 degrees, so the angle between the chord and one of the radii is 22.5 degrees. We can use trigonometry to find the length of the chord:

cos(22.5) = adjacent/hypotenuse

cos(22.5) = x/4

x = 4cos(22.5)

So the length of the chord is approximately 3.54 cm (rounded to two decimal places).

The area of the triangle can be found using the formula:

A = (1/2)bh

where b is the length of the base (which is the chord) and h is the height (which is the distance from the midpoint of the chord to the center of the circle). The height is equal to the radius minus half the length of the chord:

h = 4 - (3.54/2)

h = 1.23 (rounded to two decimal places)

Substituting the values of b and h, we get:

A = (1/2)(3.54)(1.23)

A = 2.17 (rounded to two decimal places)

So the area of the triangle is approximately 2.17 square cm.

Finally, we can find the area of the segment by subtracting the area of the triangle from the area of the sector:

Area of segment = Area of sector - Area of triangle

Area of segment = 2π - 2.17

Area of segment = 0.85 (rounded to two decimal places)

Therefore, the area of the segment of the circle is approximately 0.85 square cm.

Answer: Let's use algebra to check if Tim is correct.

Let x be the original price of the jeans.

When the jeans are marked down by 20%, the new price becomes:

x - 0.2x = 0.8x

Tim claims that if we increase the new price by 20%, we will get the original price:

0.8x + 0.2(0.8x) = x

Simplifying the left-hand side:

0.8x + 0.16x = x

0.96x = x

This is not true for all values of x, which means that Tim's claim is not correct.

Let's use the given information that the original price is $200 to find out what the new price is after the 20% discount:

New price = Original price - Discount

New price = $200 - 20% of $200

New price = $200 - $40

New price = $160

If we increase the new price of $160 by 20%, we get:

New price + 20% of new price

$160 + 20% of $160

$160 + $32

$192

This is not equal to the original price of $200, so we can conclude that Tim's claim is incorrect.

1:The system of linear equations can be rewritten as:

4x + y = 4 ...(1)

y = -4a + 4 ...(2)

To determine the classification of the system, we can use the method of substitution:

Substituting equation (2) into equation (1) to eliminate y:

4x + (-4a + 4) = 4

4x - 4a = 0

x - a = 0

x = a

Substituting x = a into equation (2) to find the value of y:

y = -4a + 4

So the solution of the system is (x,y) = (a, -4a+4).

Since the system has a unique solution for any value of 'a', it is a consistent independent system of equations.

2:To find the solution to the equation f(x) = g(x), we need to find the value of x that makes the two functions equal.

f(x) = 2^x + 1

g(x) = -x + 7

Setting them equal to each other:

2^x + 1 = -x + 7

Subtracting 1 from both sides:

2^x = -x + 6

Taking the logarithm of both sides (base 2):

x = log2(-x + 6)

Since log2(-x + 6) is only defined when -x + 6 is positive, we need to check if -x + 6 > 0.

-x + 6 > 0

x < 6

Therefore, the solution to the equation f(x) = g(x) is the intersection point of the two graphs for x < 6.

To graph the two functions, we can use a graphing calculator or plot points. Here are some points for each function:

f(x) = 2^x + 1

(0, 2)

(1, 3)

(2, 5)

(3, 9)

g(x) = -x + 7

(0, 7)

(1, 6)

(2, 5)

(3, 4)

Plotting these points on the same coordinate plane:

We can see that the two functions intersect at approximately (2.6, 4.4) for x < 6. Therefore, the solution to the equation f(x) = g(x) for x < 6 is approximately x = 2.6.

(a) Diverges

(b) Diverges

(c) Converges

(d) Converges: The original series converges when x = -4 and diverges when x = 6. For (a), (b), and (c), the x value remains the same as in the original series, so the convergence or divergence of the series is the same as the original series. However, for (d) the x value has changed. The (-1) in the series acts as a multiplier and flips the convergence of the original series, so the series converges.

The convergence or divergence of a series is determined by the value of x in the series. In this particular case, when x = -4 the original series converges, and when x = 6 it diverges. For (a), (b), and (c), the x value is the same as in the original series, so the convergence or divergence of the series is the same as the original series. However, for (d), the x value has changed, as the (-1) in the series acts as a multiplier and flips the convergence of the original series.

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

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

Using this formula, we can find the distance between the points (-3, 6) and (-8, -6) as follows:

d = sqrt((-8 - (-3))^2 + (-6 - 6)^2)

If a store sells two types of shirts. The number of short-sleeved shirts that were sold than long-sleeved shirts is 24 shirts.

Number of short-sleeved shirts sold =S

Number of long-sleeved shirts sold = L

we know that:

s + l = 48 (equation 1) -- Total number of shirts sold

12s + 16l = 624 (equation 2) -- Total cost of shirts sold

To solve for the number of short-sleeved shirts sold, we can use equation 1 to express "l" in terms of "s":

l = 48 - s

Substituting this into equation 2

12s + 16(48 - s) = 624

Simplifying and solving for "s"

12s + 768 - 16s = 624

-4s = -144

s = 36

Therefore, 36 short-sleeved shirts were sold.

To find the number of long-sleeved shirts sold, we can use equation 1 again:

To calculate the probability of this event occurring, we can use the formula:

Where P(A) is the probability of the event occurring, n(A) is the number of favorable outcomes, and n(S) is the total number of possible outcomes.

In this case, the number of favorable outcomes is 1, since there is only one team that has two people with the same birthday. The total number of possible outcomes is 16, since there are 16 teams.

Therefore, the probability of two people on the same team having the same birthday is:

P(A) = 1 / 16

So, the probability of this event occurring is 1/16.
