Use the Law of Sines or the Law of Cosines to solve each triangle.
(DRAW TRIANGLES ON YOUR WORKSHEET - IT WILL HELP!)
Round all angle measures to the nearest tenth of a degrees and side lengths to the nearest tenth.
The law of sines and the law of cosines are used to solve triangles. These formulas aid in finding the missing angle or side of a triangle based on the known side lengths and angle measures.A triangle has three sides and three angles. If we know all three sides and all three angles, we can find everything there is to know about that triangle. Unfortunately, this is rare.
We can use the law of sines or the law of cosines to solve a triangle if we know some, but not all, of the side lengths and angle measures.The law of sines, abbreviated L.S., is a formula that relates the side lengths and angles of a triangle. The L.S. formula is as follows:
a/sin A = b/sin B = c/sin C. In this formula, a, b, and c are the lengths of the sides of a triangle, while A, B, and C are the angles opposite those sides. Any two ratios in this formula can be utilized to solve for the third.The law of cosines, abbreviated L.C., is a formula that relates the side lengths and angles of a triangle. The L.C. formula is as follows: a^2 = b^2 + c^2 - 2bc cos A (similarly for the other sides).
In this formula, a, b, and c are the lengths of the sides of a triangle, while A, B, and C are the angles opposite those sides. This formula may be used to solve for one of the missing side lengths or one of the missing angles of the triangle if we know the length of two sides and the angle between them.

Given:
slope = -3/4
point (x1,y1) = (2, -1)
Substitute and solve
[tex]m = \frac{y-y1}{x-x1} \\-\frac{3}{4} = \frac{y-(-1))}{x-2} \\-3(x-2) = 4(y+1)\\-3x + 6 = 4y + 4 \\Transpose\\4y = -3x + 6 - 4\\4y = -3x + 2 \\y = -3/4x + 2/4\\y = -3/4x + 1/2\\OR\\4y +3x - 2 = 0[/tex]

The formula for the radius (r) of a sphere, given the volume (V), is [tex]r = \sqrt[3]{ \frac{3V} {4\pi} }[/tex].
To solve the formula for the volume of a sphere, [tex]V = \frac 43 \pi r^3[/tex], for r, we'll follow these steps:
1. Begin with the formula for the volume of a sphere: [tex]V = \frac 43 \pi r^3[/tex].
2. Multiply both sides of the equation by (3/4) to isolate π[tex]r^3[/tex]:
[tex]\frac34V = \pi r^3[/tex].
3. Divide both sides of the equation by π to obtain the expression for r^3:
[tex]r^3 = \frac34 \frac V\pi[/tex].
4. To solve for r, take the cube root of both sides of the equation:
[tex]r = \sqrt[3]{ \frac{3V} {4\pi} }[/tex].
Therefore, the formula solved for r is [tex]r = \sqrt[3]{ \frac{3V} {4\pi} }[/tex]. This formula allows you to calculate the radius of a sphere when the volume (V) is given.

Answer:
Step-by-step explanation:
Salary offered to Emily after college = $35000
Rise in her salary = $2000 every year
Let she works for x years in the company,
Salary rise in her salary = $2000x
Total salary after x years = $(35000 + 2000x)
The independent variable x represents NUMBER OF YEARS and dependent variable is the TOTAL SALARY,because the SALARY depends on the NUMBER OF YEARS WORKED.
A function these variables is C(x) = 35000 + 2000x
So, C(4) = 35000 + 2000(4) = 43000, meaning 4 years later Emily will earn a salary $43000.

Suppose you have a $1,350 charge on a credit card charging 1.5% monthly interest using the adjustable balance method. The minimum payment due in May is $45. How much will you save in interest charges in June by paying $90 instead?
Paying $90 instead of the minimum payment of $45, you would save $1.35 in interest charges in June
To calculate the interest charges in June, we need to understand how the adjustable balance method works. This method calculates interest based on the average daily balance for the billing cycle.
Step 1: Calculate the average daily balance for May. To do this, we need to know the number of days in May and the balance on each day. Let's assume May has 31 days. Since the balance remains constant at $1,350, the average daily balance for May is $1,350.
Step 2: Calculate the interest charges for May. Multiply the average daily balance by the monthly interest rate. In this case, the interest charges for May would be $1,350 * 0.015 = $20.25.
Step 3: Calculate the interest charges for June. Assuming the balance remains the same at $1,350, the average daily balance for June would also be $1,350.
Step 4: Calculate the interest charges for June with a payment of $90. To do this, we need to subtract the payment from the average daily balance for June. In this case, the adjusted balance would be $1,350 - $90 = $1,260.
Step 5: Multiply the adjusted balance by the monthly interest rate to calculate the interest charges for June. In this case, the interest charges for June would be $1,260 * 0.015 = $18.90.
Step 6: Calculate the savings in interest charges. To find the difference in interest charges, subtract the interest charges for June with the $90 payment from the interest charges for June with the minimum payment. In this case, the savings in interest charges would be $20.25 - $18.90 = $1.35.

A person leaves home and walks 4 miles west, then 5 miles southwest.
How far from home is she?
miles
In what direction must she walk to head directly home?
degrees North of East
The person is approximately 8.43 miles from home, and they need to walk in the direction of approximately 26.6 degrees east of north to head directly home.
To determine the distance from home, we can use the concept of vector addition. The person walks 4 miles west, which can be represented as a vector (-4, 0) in a coordinate plane. Then, they walk 5 miles southwest, which can be represented as a vector (-3.54, -3.54) since southwest is a combination of west and south. Adding these two vectors together gives us (-7.54, -3.54).
To find the magnitude or distance from home, we use the Pythagorean theorem. The distance is given by sqrt((-7.54)^2 + (-3.54)^2) = 8.43 miles (approximately).
To determine the direction to head directly home, we need to find the angle between the vector (-7.54, -3.54) and the positive x-axis. We can use trigonometry to find this angle. The tangent of the angle is given by the ratio of the y-coordinate to the x-coordinate, which is -3.54 / -7.54. Taking the inverse tangent of this value gives us approximately 26.6 degrees.

An aquarium holds 11.35 cubic feet of water, and is 2.6 feet long and 1.1 feet wide. What is its depth? Round your answer to the nearest whole number.
The depth is
feet.
The depth of the aquarium is approximately 4 feet when rounded to the nearest whole number (since 3.64 is closer to 4 than it is to 3 when rounded to the nearest whole number).
To calculate the depth of the aquarium, we need to use the formula for volume of a rectangular prism,
which is V = lwh where V is the volume, l is the length, w is the width, and h is the height (or depth, in this case).
Given that the aquarium holds 11.35 cubic feet of water, the volume of the aquarium can be represented by V = 11.35 cubic feet.We are also given that the length of the aquarium is 2.6 feet and the width is 1.1 feet.
Substituting these values into the formula for volume,
we get:11.35 = 2.6 × 1.1 × h
Simplifying this expression:
11.35 = 2.86h
Dividing both sides by 2.6 × 1.1,
we get:h ≈ 3.64 feet (rounded to two decimal places)
