what is the value of x to the nearest tenth
Answer:
x ≈ 24.7
Step-by-step explanation:
Using the Sine rule in the triangle , that is
[tex]\frac{x}{sin71}[/tex] = [tex]\frac{15}{sin35}[/tex] ( cross- multiply )
x × sin35° = 15 × sin71° ( divide both sides by sin35° )
x = [tex]\frac{15sin71}{sin35}[/tex] ≈ 24.7 ( to the nearest tenth )
Two roots of a third degree polynomial function f(x) are –4 and 4. Which statement describes the number and nature of all roots for this function?
f(x) has three imaginary roots.
f(x) has three real roots.
f(x) has two real roots and two imaginary roots.
f(x) has three real roots and one imaginary root.
Answer:
Step-by-step explanation:
A third degree polynomial has a total of three roots, real and imaginary combined.
If it already has 2 real roots, -4 and +4, then it has to have three real roots because imaginary roots come in conjugate pairs, i.e. they come in even numbers.
Answer:
Three real roots

Find the volume of the shape with the given dimensions 8 in by 5 in by 3 in
Answer:
V = (8 in)(5 in)(3 in) = 120 in^3
Step-by-step explanation:
The likeliest name for this shape is "rectangular prism." Let's assume that the length, L, is 8 in; the width, W, is 5 in; and the height, H, is 3 in.
Then the volume of this rectangular prism is V = L * W * H, or
V = (8 in)(5 in)(3 in) = 120 in^3

You are given a bag with 3 cubes (1 green and 2 white). You put all 3 cubes in a bag and shake the
bag and pick a cube. If you pick a green cube, you get 2 points. If you pick a white cube, you lose 1
point. What is the expected value for the game?
Answer:
-1 (losing a point)
Step-by-step explanation:
it is a probability question
total possible outcomes= 3
favourable outcome(white) = 2
probability of getting a white is 2/3
probability of getting a green is 1/3
so the expected value of the game will be -1

A bag contains 8 red balls and 6 blue
balls.
Radhika takes three balls at random
from the bag, without replacement.
Calculate the probability that the three
balls are the same colour. *
Answer:
The probability that all 3 balls are red is 18.65%, while the probability that all 3 balls are blue is 7.87%.
Step-by-step explanation:
Since a bag contains 8 red balls and 6 blue balls, and Radhika takes three balls at random from the bag, without replacement, to calculate the probability that the three balls are the same color, the following mathematical operations must be performed:
8 + 6 = 14
14 = 100
8 = X
8 x 100/14 = X
800/14 = X
57.14 = X
100 - 57.14 = 42.86
0.5714 ^ 3 = X
0.1865 = X
0.4286 ^ 3 = X
0.0787 = X
Therefore, the probability that all 3 balls are red is 18.65%, while the probability that all 3 balls are blue is 7.87%.

What is the volume of this triangular prism? A triangular prism. The triangular base has a base of 28 centimeters and height of 22.4 centimeters. The height of the prism is 18.1 centimeters. 313.6 506.8 5,676.16 11,352.32
Answer:
The volume of the triangular prism is 5676.16 cm³
Step-by-step explanation:
The area of the triangular base A = bh/2 where b = base = 28 cm and h = height = 22.4 cm.
Now, the volume of the triangular prism, V = area of triangular base, A × height of prism, h'
V = Ah' where h = height of prism = 18.1 cm
So, V = bhh'/2
Substituting the values of the variables into the equation for V, we have
V = bhh'/2
V = 28 cm × 22.4 cm × 18.1 cm/2
V = 14 cm × 22.4 cm × 18.1 cm
V = 5676.16 cm³
So, the volume of the triangular prism is 5676.16 cm³
Answer:
5676.16 cm³

9514 1404 393
Answer:
∠GDH = ∠GHD = 50°
Step-by-step explanation:
Angles FGD and EDG are alternate interior angles, so are congruent. That means angle EDG is 100°. The angle sum theorem tells us ...
∠EDG = ∠EDH +∠HDG
100° = 50° +∠HDG
50° = ∠HDG
You can find the measure of ∠DHG a couple of different ways. It is an alternate interior angle congruent to ∠EDH, so is 50°. It is one of two remote interior angles that have a sum equal to the exterior angle FGD, so is ...
∠DHG = ∠FGD -∠HDG = 100° -50° = 50°
So, angles DHG and HGD both have measures of 50°. When a triangle has two angles with the same measure, it is an isosceles triangle.

A recipe for a smoothie for 0.75 pound of strawberries. If Kerry has 3.15 pounds of strawberries, how many batches of the recipe can She make
Answer:
4 batches
Step-by-step explanation:
To obtain the number of batches of the recipe that can be made ;
We take the divison of the total amount of strawberry by the amount of strawberry required per batch :
Pounds of strawberry per recipe = 0.75 pound
Total pounds of strawberry = 3.15 pound
= 3.15 / 0.75
= 4.2
We round down :
4.2 batches = 4 batches of the recipe can be made

Latoya is a software saleswoman. Let represent her total pay (in dollars). Let represent the number of copies of English is Fun she sells. Suppose that and are related by the equation . Answer the questions below. Note that a change can be an increase or a decrease. For an increase, use a positive number. For a decrease, use a negative number. What is the change in Latoya's total pay for each copy of English is Fun she sells
Answer:
The answer is "$80".
Step-by-step explanation:
Please see the attached file for the whole question.
Yolanda's total pay y changes for each 'English is fun' sold x, i.e.
[tex]\frac{\delta y}{\delta x} = \frac{dy}{dx} \\\\y = 1900+80 x[/tex]
separating the above equation:
[tex]\frac{dy}{dx}= 80[/tex]
Therefore,
[tex]\frac{dy}{dx} = \$80[/tex]
For each 'English is enjoyable' sold x, the change in Yolanda total compensation y is [tex]\$80[/tex].
