A.
60°
B.
42°
C.
96°
D.
69°
If the triangle is isosceles, then the measure of the third angle could be 42 degrees
Which could be the measure of the third angle?From the question, we have the following parameters that can be used in our computation:
One angle has a measure of 42° Another angle has a measure of 96°.The sum of angles in a triangle is 180 degrees
If the triangle is isosceles, then we have the following possible sum of angles
Sum 1 = 42 + 96 + 96 = 234 -- false
Sum 1 = 42 + 96 + 42 = 180 -- true
Hence, if the triangle is isosceles, then the measure of the third angle could be 42 degrees

You are at the grocery store choosing between bananas and walnuts. You know that the price of walnuts is $2 per pound and the price of bananas is $1 per pound, and your satisfaction from consuming is given by the following utility function: U=W .5
B .5
a. What is your marginal rate of substitution of walnuts for bananas? b. Using the Lagrangian approach, find your optimal consumption bundle. What is your total utility at this level? c. If the price of bananas doubles to $2 per pound, how much income must you have to maintain the same level of utility?
a. MRS = √(W/B)
b. Optimal bundle and total utility.
c. Adjusted income for constant utility.
a. The marginal rate of substitution (MRS) of walnuts for bananas is the rate at which you are willing to give up walnuts in exchange for one additional pound of bananas while keeping the utility constant. In this case, the MRS is equal to the ratio of the marginal utility of walnuts to the marginal utility of bananas. Since the utility function is U = √(W * B), the MRS can be calculated as MRS = √(W/B).
b. Using the Lagrangian approach, we can set up the following optimization problem: maximize U = √(W * B) subject to the constraint 2W + B = I, where W represents the pounds of walnuts, B represents the pounds of bananas, and I represents income. By solving the Lagrangian equation and the constraint, we can find the optimal consumption bundle and income level.
c. If the price of bananas doubles to $2 per pound, we need to determine the income required to maintain the same level of utility. With the new price, the constraint becomes 2W + 2B = I. By solving the Lagrangian equation again and substituting the new constraint, we can find the income level required to maintain the same level of utility.

How do you solve this?
Step-by-step explanation:
g(x) is also called y. the functional result value for an input value x is shown in the y direction above or below that x value on the x axis.
so, when it says g(x) = c, the solution is to find the values of x for which b the function g delivers c as result.
now, we look at the graphic.
for example, g(x) = 0 (c = 0) has actually 3 solutions, as the function crosses the x-axis (and that means y or g(x) = 0) 3 times. so, there are 3 different values of x that create g(x) = 0.
but we are looking for a c that has only one solution (one value of x to create that result).
c = 1 ?
let's imagine a horizontal line through y = 1.
we see, it cuts the function also 3 times. 3 solutions.
c = -1 ?
a similar horizontal line through y = -1 cuts the function also 3 times. 3 solutions
but c = 3 !
a horizontal line through y = 3 stays above all the waves of the function and then cuts the function only one time at the very right. 1 solution !
and that is therefore our answer.

5. Find the equation of the plane that passes through the points P=(1,3,2), Q=(3,-1,6), and R=(5,2,0)
To find the equation of the plane that passes through the points P(1, 3, 2), Q(3, -1, 6), and R(5, 2, 0), we can use the following steps.
Step 1: Find two vectors in the plane by calculating PQ and PR. PQ = Q - P = (3, -1, 6) - (1, 3, 2) = (2, -4, 4)PR = R - P = (5, 2, 0) - (1, 3, 2) = (4, -1, -2)Step 2: Find the cross product of the two vectors calculated in step 1. This will give us a vector that is normal to the plane. PQR = PQ × PR = (2, -4, 4) × (4, -1, -2) = (-14, 16, 14)Step 3: Find the equation of the plane using the point-normal form. The equation of the plane is: (x - 1) (-14) + (y - 3) (16) + (z - 2) (14) = 0-14x + 16y + 14z = 78Therefore, the equation of the plane that passes through the points P(1, 3, 2), Q(3, -1, 6), and R(5, 2, 0) is -14x + 16y + 14z = 78.Main answer:To find the equation of the plane, we used the point-normal form. In this form, the equation of the plane is given by:(x - x1)A + (y - y1)B + (z - z1)C = 0Where (x1, y1, z1) is a point on the plane, and A, B, and C are the direction cosines of the normal to the plane.In this case, we found two vectors PQ and PR in the plane by calculating the difference between the coordinates of the given points. We then found the cross product of these vectors to get a vector that is normal to the plane. Finally, we used the point-normal form of the equation to find the equation of the plane that passes through the given points.
Therefore, the equation of the plane that passes through the points P(1, 3, 2), Q(3, -1, 6), and R(5, 2, 0) is -14x + 16y + 14z = 78.

I need help
Answer:
\(10\:\mathrm{meters}\)
Step-by-step explanation:
We can use trigonometry for a right triangle to solve this problem:
\(\tan 18^{\circ}=\frac{h}{30},\\h=30\cdot\tan 18^{\circ},\\h\approx \fbox{$10\:\mathrm{m}$}\).
The height of the flagpole is 10 meters.
What is angle of elevation?"It is the angle from the horizontal upward to an object."
For given question,
Consider the following figure.
The angle of elevation is 18°
⇒ ∠ACB = 18°
Also, BC = 30 meters
We need to find the height of the flagpole i.e., we need to find the distance AB.
Consider a tan(∠ACB )
\(\Rightarrow tan(18^{\circ})=\frac{AB}{BC}\\\\ \Rightarrow 0.3249 = \frac{AB}{30}\\\\ \Rightarrow AB=9.747 ~~meters\\\\\Rightarrow AB\approx 10~~meters\)

Solve the triangle. B=67∘51′,c=36m,a=74m What is the length of side b ? b=m (Round to the nearest whole number as needed.) What is the measure of angle A ? A= (Round to the nearest whole number as needed.) What is the measure of angle C ? C= (Round to the nearest whole number as needed.)
The length of side b is 56m, angle A is 45°, and angle C is 67°.
What is the length of side b in the given triangle?In the given triangle with side lengths a = 74m, b ≈ 56m, and c = 36m, the length of side b is approximately 56m.
To solve the triangle, we can use the Law of Cosines and the fact that the sum of angles in a triangle is 180 degrees. Given angle B = 67°51', we have:
Length of side b:Using the Law of Cosines, we have:
b² = a² + c² - 2ac * cos(B)
Substituting the known values:
b² = 74² + 36² - 2 * 74 * 36 * cos(67°51')
Calculating the value of b:
b ≈ √(74² + 36² - 2 * 74 * 36 * cos(67°51'))
b ≈ 55.92m (rounded to the nearest whole number, b ≈ 56m)
Measure of angle A:Using the Law of Cosines again, we have:
cos(A) = (b² + c² - a²) / (2 * b * c)
Substituting the known values:
cos(A) = (56² + 36² - 74²) / (2 * 56 * 36)
Calculating the value of A:
A = cos⁻¹((56² + 36² - 74²) / (2 * 56 * 36))
A ≈ 45° (rounded to the nearest whole number)
Measure of angle C:Using the fact that the sum of angles in a triangle is 180 degrees:
C = 180° - A - B
Substituting the known values:
C ≈ 180° - 45° - 67°51'
Calculating the value of C:
C ≈ 67°9' (rounded to the nearest whole number, C ≈ 67°)
Therefore, in the given triangle, the length of side b is approximately 56m, angle A is approximately 45°, and angle C is approximately 67°.

MD - Multiplication or Division (Whichever comes first)
DA - Division or Addition (Whichever comes first)
So:
15-1(12÷4+1) -> first evaluate the parenthesis
(12÷4+1) -> Inside the parenthesis, first evaluate the Division:
12÷4 = 3
so (12÷4+1) = (3+1) = 4
So; 15-1(4) -> evaluate the multiplication first:
1(4) = 4
so: 15-4 = 11

Step-by-step explanation:
To find the number of sides a polygon has giving an interior angle, use the equation:
(number of sides - 2)*180/(number of sides) = measure of interior angle
15. (n = number of sides)
((n-2)*180)/n = 170
180n-360 = 170n
10n = 360
n = 36 (d)
16. (n = number of sides)
((n-2)*180)/n = 162
180n-360 = 162n
18n = 360
n = 20 (b)
17. The sum of the interior angles of a triangle is always 180 (d)
