Find the sine of ∠Y. Simplify your answer and write it as a proper fraction, improper fraction, or whole number.
Answers
Angle Y from the given triangle XYZ is 62° and sine of ∠Y is 60/68.
From the given triangle XYZ, XY=32 and YZ=68.
By using Pythagoras theorem, we get
YZ²=XY²+XZ²
68²=32²+XZ²
XZ²=68²-32²
XZ²=3600
XZ=√3600
XZ=60
We know that, sinθ= Opposite/Hypotenuse
sinY=XZ/YZ
sinY=60/68
sinY=0.8823
Y=61.92
Y≈62°
Therefore, angle Y from the given triangle XYZ is 62° and sine of ∠Y is 60/68.

Use the given zero to find the remaining zeros of the function.
h(x)=3x^4+10x³+19x^2+90x-72; zero: -3i
The remaining zeros of h are ___
(Use a comma to separate answers as needed. Use integers or fractions for any numbers in the expression.)
Answers
Answer:
Since the coefficients of the polynomial function h(x) have real values, if -3i is a zero of h(x), then its complex conjugate 3i must also be a zero of h(x). This is known as the Complex Conjugate Root Theorem.
Therefore, the remaining zeros of h(x) can be found by dividing the polynomial by the factors (x - (-3i)) and (x - 3i), using either polynomial long division or synthetic division. Here, we'll use synthetic division:
3i | 3 10 19 90 -72
| 9i -63 -216 -294
+-----------------------
3 10+9i -44 -126 -366
Step-by-step explanation:
The quotient is 3x^3 + (10+9i)x^2 - 44x - 126, and the remainder is -366. This tells us that:
h(x) = (x - (-3i))(x - 3i)(3x^3 + (10+9i)x^2 - 44x - 126)
The remaining zeros of h(x) can now be found by solving the cubic polynomial 3x^3 + (10+9i)x^2 - 44x - 126. This can be done using various methods such as the Rational Root Theorem, factoring by grouping, or numerical methods. However, these methods can be quite involved and may not always lead to exact answers.
Ali made $144 for 9 hours of work. At the same rate, how much would he make for 7 hours of work
Answers
$144 / 9 hours = x / 7 hours
To solve for x, we can cross-multiply:
9 hours * x = $144 * 7 hours
Divide both sides by 9 to isolate x:
x = ($144 * 7 hours) / 9 hours
Simplifying this expression, we get:
x = $112
Therefore, Ali would make $112 for 7 hours of work at the same rate.
Answer: 112
Step-by-step explanation:
Take 144/9 to find how much he makes in a single hour. 144/9 is 16, 16*7=112. Which is how much he will make working 7 hours at the same rate.

Answers
The area of the trapezium is 30 square centimeters at the values of h = 4 cm, b = 10 cm, and b' = 5 cm.
We can use the formula for the area of a trapezoid:
A = 1/2 * h * (b + b')
Substituting the given values, we get:
A = 1/2 * 4 cm * (10 cm + 5 cm)
Simplifying the expression inside the parentheses:
A = 1/2 * 4 cm * 15 cm
Multiplying:
A = 30 cm²
Therefore, when h = 4 cm, b = 10 cm, and b' = 5 cm, the area of the trapezoid is 30 square centimeters.

The perimeter of parallelogram ABCD is cm. AD is cm more than twice AB. Find the lengths of all four sides of ABCD.
Answers
So the lengths of all four sides of ABCD are:
AB = BC = 15 cm
CD = DA = 31 cm
Let AB = x. Then AD = 2x + 1, since AD is 1 cm more than twice AB.
Since ABCD is a parallelogram, opposite sides are equal in length. So, BC = AB = x, and DC = AD = 2x + 1.
The perimeter of the parallelogram is the sum of the lengths of all four sides:
AB + BC + CD + DA = x + x + (2x + 1) + (2x + 1) = 6x + 2
We are given that the perimeter is 92 cm, so we can set this expression equal to 92 and solve for x:
6x + 2 = 92
6x = 90
x = 15
Therefore, AB = BC = 15 cm and AD = DC = 2(15) + 1 = 31 cm.

Watermelons needed to be loaded up from the farm to go to the local market.
The mass of the load on the truck is 56 kilograms. If the mass of each watermelon is 7 kilograms, how many watermelons are on this load?
Show your work.
Answers
If the mass of each watermelon is 7 kilograms, there are 8 watermelons on the load.
To find the number of watermelons on the load, we need to divide the total mass of the load by the mass of each watermelon. We can set up an equation to represent this:
Number of watermelons = Total mass of load / Mass of each watermelon
Plugging in the given values, we get:
Number of watermelons = 56 kg / 7 kg per watermelon
Simplifying, we get:
Number of watermelons = 8
Therefore, there are 8 watermelons on the load.
It's important to note that this calculation assumes that all the watermelons have the same mass of 7 kg. In reality, there may be some variation in the mass of the individual watermelons, which could affect the total number of watermelons on the load. Additionally, other factors such as the size and shape of the watermelons may also affect how many can fit on the truck.

Answers
The solution to the inequality is -3 ≤ x ≤ -1/3
Solving inequality with modulusGiven the inequality:
4|3x+5| ≤ 16
Let us simplify it by dividing both sides by 4 to get:
|3x+5| ≤ 4
Next, we can break the inequality into two cases, depending on whether 3x+5 is positive or negative:
First: 3x+5 ≥ 0
In this case, the inequality simplifies to:
3x+5 ≤ 4
Subtracting 5 from both sides, we get:
3x ≤ -1
Dividing by 3 (which is positive) gives:
x ≤ -1/3
Second: 3x+5 < 0
In this case, the inequality simplifies to:
-3x-5 ≤ 4
Adding 5 to both sides, we get:
-3x ≤ 9
Dividing by -3 (which is negative and requires us to flip the inequality), gives:

The coefficients of the function and their meaning are described as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.The function in this problem is given as follows:
y = 6x + 5.
A proportional relationship is a special case of a linear function with an intercept of zero, hence we must subtract by 5 as follows:
y = 6x + 5 - y
y = 6x.
