FInd the approximations to at least two decimal places for the coordinates of Point Z in the figure below. The angle theta or Q is -80 degrees and the radius is 11.
Z = ?
Also if you can explain to me, that would be great.
Point Z's polar coordinates can be found by using the formulas x = r*cos(θ) and y = r*sin(θ), converting the angle from degrees to radians first. Use r = 11 and θ = -80 degrees.
Explanation:This question deals with the concept of polar coordinates, coordinates given by a distance from the origin (radius) and an angle from the positive x-axis (-80 degrees in this case). Point Z's coordinates can be found using the formulas: x = r*cos(θ) and y = r*sin(θ). Here r (the radius) is 11 and θ is -80 degrees, but remember we need to convert this angle to radians because the trigonometric functions in most calculators use radians. That can be done using the formula: Radians = Degrees * (π / 180). Hence calculate x and y to find Point Z.

The tree in Carlos backyard is 5 meters high. How high is it in centimeters?
Final answer:
The tree in Carlos' backyard is 5 meters high, which is equivalent to 500 centimeters because there are 100 centimeters in a meter. Multiplying 5 meters by 100 gives us the height in centimeters.
Explanation:
To convert the height of the tree in Carlos' backyard from meters to centimeters, we need to know the conversion factor between these two units of measurement. There are 100 centimeters in a meter. Therefore, if the tree is 5 meters high, to find its height in centimeters, we multiply 5 meters by 100.
5 meters × 100 centimeters/meter = 500 centimeters
So, the tree is 500 centimeters tall when converted from meters. This is similar to the example given where Corey measures a distance of 8 meters between two trees and wants to convert that measurement to centimeters. In this concept, we are provided insight into converting with metric units of measurements which is crucial for accurately understanding dimensions in different units.
a projectile is launched straight up from ground level with an initial velocity of 320 ft/sec when will it's height above ground be
1538 feet
To calculate when the height of the projectile will be 1538 feet, use the kinematic equation and solve the quadratic equation for time.
Explanation:To calculate when the height of the projectile will be 1538 feet, we can use the kinematic equation for free-falling objects. The equation is: h = [tex]h0 + v0*t - 16*t^2,[/tex] where h is the height above ground, h0 is the initial height (0 in this case), v0 is the initial velocity (320 ft/sec in this case), and t is the time.
Substituting the given values into the equation, we have: 1538 = 0 + 320*t - 16*t^2. Rearranging this equation, we get: [tex]16*t^2[/tex]- 320*t + 1538 = 0.
Now we can solve this quadratic equation for t by using the quadratic formula: t = (-b ± sqrt([tex]b^2[/tex] - 4ac)) / (2a), where a = 16, b = -320, and c = 1538. Plugging in these values, we can calculate the values of t.

Solution. Notice that
2(−1)4 − 3(−1)3 − 4(−1)2 − (−1) − 1 = 1 .
So x − (−1) must divide 2x^4 − 3x^3 − 4x^2 − x − 2. Do polynomial long division to get 2x^4 − 3x^3 − 4x^2 – x – 2 / (x − (−1)) = 2x^3 − 5x^2 + x – 2.
Let ε > 0. Set δ = min{ ε/40 , 1}. Let x be a real number such that 0 < |x−(−1)| < δ. Then |x + 1| < ε/40 . Also, |x + 1| < 1, so −2 < x < 0. In particular |x| < 2. So
|2x^3 − 5x^2 + x − 2| ≤ |2x^3 | + | − 5x^2 | + |x| + | − 2|
= 2|x|^3 + 5|x|^2 + |x| + 2
< 2(2)^3 + 5(2)^2 + (2) + 2
= 40
Thus, |2x^4 − 3x^3 − 4x^2 − x − 2| = |x + 1| · |2x^3 − 5x^2 + x − 2| < ε/40 · 40 = ε.
The Sugar Sweet Company is going to transport its sugar to market. It will cost $6500 to rent trucks, and it will cost an additional $250 for each ton of sugar transported. Let C represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported. Write an equation relating C to S . Then use this equation to find the total cost to transport 19 tons of sugar.
Answer: Equation relating C to S : [tex]C=6500+250S[/tex]
The total cost to transport 19 tons of sugar is $11, 250.
Step-by-step explanation:
Given : It will cost $6500 to rent trucks, and it will cost an additional $250 for each ton of sugar transported.
Total cost = $6500 + $250 x (amount of sugar transported ( in tons))
Let C represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported.
Then, the equation relating C to S would be : [tex]C=6500+250S[/tex]
When S= 19 , we get
[tex]C=6500+250(19)=6500+4750= 11250[/tex]
Hence, the total cost to transport 19 tons of sugar would be $11, 250.
An equation that relates Cost to the amount of sugar S
C = 6500 + 250S
The total cost is $1120
The total cost of transporting 19 tons of sugar at 250 eachC = total cost
C = 6500 + 250(19)
Total cost = 6500 + 4750
= 11250
Therefore the total cost of transporting the 19 tons of sugar is $11250

Manuel rented a truck for one day. There was a base fee of $14.95, and there was an additional charge of 87 cents for each mile driven. Manuel had to pay $248.98 when he returned the truck. For how many miles did he drive the truck?
Final answer:
After calculations, it is determined that Manuel drove approximately 269 miles.
Explanation:
Manuel rented a truck which had a base fee of $14.95 and an additional charge of 87 cents per mile. To find the number of miles driven, we need to subtract the base fee from the total amount paid and then divide by the cost per mile.
First, subtract the base fee from the total cost:
Total amount paid = $248.98
Base fee = $14.95
Amount paid for miles = $248.98 - $14.95 = $234.03
Next, divide the amount paid for miles by the cost per mile:
Cost per mile = 87 cents = $0.87
Number of miles driven = $234.03 / $0.87 = 269 miles (approximately)
Therefore, Manuel drove approximately 269 miles with the rented truck.

Find a vector parametric equation for the parabola y=x2 from the origin to the point (3,9) using t as a parameter.
The parametric vector equations for the parabola y=x² from the origin to the point (3,9) is x = t and y = t² for the parameter range 0 <= t <= 3.
Explanation:The required parametric vector equation for the parabola y=x² from the origin to the point (3,9) is given by the equations x = t and y = t². Here, t is the parameter. At t=3, these equations give us the coordinates x=3 and y=9, which corresponds to the point (3,9).

In the parametric form, the path of a point on the parabola y=x² from the origin to point (3,9) is represented by a vector (t, t²) with t ranging from 0 to 3.
Explanation:To find a vector parametric equation for the parabola y=x² from the origin to the point (3,9), we first need to understand that the parabola y = x² is not a vector in itself.
But, we can describe its trajectory through a parametric form using t as a parameter. For a given t, the parabola is represented by a vector (x(t), y(t)), where x(t) and y(t) are functions of t. For the specific parabola y = x², we can define the functions as x(t) = t and y(t) = t².
This means the vector at time t is given by (t, t²). From the origin (0,0) to the point (3,9), we now have a parameter t ranging from 0 to 3.

a jar contains nickels and pennies. there are 56 coins in the jar in all. the total value of the coins is 1.52. how many pennies are in the jar
After solving the equations, it is found that there are 32 pennies in the jar.
To solve the problem of determining the number of pennies in the jar, first we establish two variables: let's denote P for the number of pennies and N for the number of nickels.
According to the problem, there are 56 coins in total, which gives us the equation P + N = 56. Also, we know that the total value of the coins is $1.52, and because each penny is worth 1 cent and each nickel is worth 5 cents, we have another equation, which is P + 5N = 152 (since there are 100 cents in a dollar).
Now we have a system of two equations to work with:
P + N = 56
P + 5N = 152
To find P, we can subtract the first equation from the second equation to eliminate P and solve for N:
0P + 4N = 96
N = 96 / 4
N = 24
Now that we know there are 24 nickels, we can find the number of pennies by substituting N back into the first equation:
P + 24 = 56
P = 56 - 24
P = 32
Therefore, there are 32 pennies in the jar.

An expression to simplify,
5x - 7 = 3x + 5
Now, Simplify the expression by combining like terms as,
5x - 7 = 3x + 5
Subtract 3x on both sides,
5x - 3x - 7 = 3x + 5 - 3x
2x - 7 = 5
Add 7 on both sides,
2x - 7 + 7 = 5 + 7
2x = 12
Divide 2 into both sides,
x = 12/2
x = 6

A newspaper finds that the mean number of typographical errors per page is six. Find the probability that (a) exactly four typographical errors are found on a page, (b) at most four typographical errors are found on a page, and (c) more than four typographical errors are found on a page.
In this case, the Poisson distribution is the best one to use. The formula for Poisson distribution is given as:
P[x] = e^-m * m^x / x!
Where,
m = mean number of typographical errors = 6

A. The probability of exactly 4 errors are found on a page is:
P[4] = e^(-6) * 6^4/4!
P[4] = 0.1339
B. The probability that at most 4 errors will be the summation of x = 0 to 4:
P[0] = e^(-6) * 6^0/0! = 2.479 E -3
P[1] = e^(-6) * 6^1/1! = 0.01487
P[2] = e^(-6) * 6^2/2! = 0.04462
P[3] = e^(-6) * 6^3/3! = 0.08924
Therefore summing up all including the P[4] in A gives:
P[at most 4] = 0.2851
C. The probability that more than 4 would be the complement of answer in B.
P[more than 4] = 1 - P[at most 4]
