In ΔOPQ, the measure of ∠Q=90°, OQ = 39, QP = 80, and PO = 89. What is the value of the tangent of ∠P to the nearest hundredth?

Answers

Final answer:

The given question is about a right triangle (ΔOPQ) where the value of the tangent of ∠P is being calculated. Using the lengths of the sides, tang P is calculated as 80/39 which is equal to 2.05 to the nearest hundredth.

Explanation:

In ΔOPQ, which is a right triangle with ∠Q being 90°, the tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle. In this case, the student wants to find the value of the tangent of ∠P.

The side opposite ∠P is QP and the side adjacent to ∠P is OQ. Given that QP = 80 and OQ = 39, we can calculate tan P as follows:

tan P = QP/OQ = 80/39 = 2.05

Therefore, to the nearest hundredth, the value of the tangent of ∠P in ΔOPQ is 2.05.

Final answer:

To find the value of the tangent of angle P in triangle OPQ, we can use the trigonometric function tangent, which is the ratio of the length of the opposite side to the length of the adjacent side. By substituting the given lengths into the formula, we can calculate the value of tangent to be approximately 0.8989.

Explanation:

In triangle OPQ, we are given that angle Q is a right angle (90 degrees), OQ is 39 units, QP is 80 units, and PO is 89 units. To find the value of the tangent of angle P, we need to use the trigonometric function tangent, which is defined as the ratio of the length of the opposite side to the length of the adjacent side.

Tan(P) = Opposite/Adjacent

In this triangle, the opposite side of angle P is QP and the adjacent side is OP. Therefore, we can substitute the given lengths into the formula:

Tan(P) = 80/89

To find the value of tangent, we can divide 80 by 89 using a calculator or decimal approximation.

Tan(P) ≈ 0.8989 (rounded to the nearest hundredth)

Hope this helps!!!

Brady

Final answer:

The elevator starts at street level (0), goes down to -4 and then rises 9 floors to reach the conference center. The sum of -4 + 9 gives 5 which is the floor number for the conference center.

Explanation:

The elevator starts at street level, which we are defining as floor 0. It then goes down 4 floors, so it's at -4. However, it then travels up to the conference center, moving a total of 9 floors. You need to add these 9 floors to where the elevator currently is. So you'll calculate -4 (the current floor number) + 9 (the number of floors it goes up) which equals 5. Therefore, the conference center is on the 5th floor.

Final answer:

The solution to the equation -3.3m = -1.1 is m = 1/3 or approximately 0.33. This was determined by dividing both sides of the equation by -3.3.

Explanation:

The problem -3.3m = -1.1 is a simple one-step equation which can be solved by isolating the variable. Here the variable is m. Dividing both sides of the equation by -3.3, we get m = (-1.1/-3.3). This simplifies to m = 1/3 ≈ 0.33. So, the solution to the equation is m = 0.33.

Which equation represents the slope-intercept form of the line below?
y-intercept = (0, -6)
slope = -5

Answers

Answer:

y = - 5x - 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 5 and c = - 6, thus

y = - 5x - 6 ← equation in slope- intercept form

The slope intercept form is y = -5x-6

What is the required equation of line ?

Given, y-intercept = (0, -6) & slope of the line = -5

The general form of an equation of line is, y = mx+c

where, m is the slope of the line & c is the y intercept

So, when x = 0 , y = -6

So, the line above passes through the point (0, -6)

The perimeter P of a square whose side length is n… is this direct variation?

Answers

The perimeter of a square is four times the side, since you have to sum all sides, and they're all the same length:

[tex]P=n+n+n+n=4n[/tex]

This is direct variation, because we have

[tex]P=4n \iff \dfrac{P}{n}=4[/tex]

and if the ratio between two variables is constant (in this case, 4), then the two variables are in direct variation.

Final answer:

The perimeter of a square is directly proportional to its side length, therefore it's an example of direct variation.

Explanation:

Yes, the perimeter (P) of a square with side length (n) is an example of direct variation. In this case, P is directly proportional to n. To understand this, think of a square. A square has four equal sides. Thus, its perimeter (P) is n times 4, or P = 4n. If n is increased, the perimeter also increases proportionally, which supports that it's a direct variation relationship. A change in one quantity leads to a proportional change in the other one.

Answers

Answer:it will be -18 gallons

Step-by-step explanation:

Answer:

To simplify 2.4 times 10¹³ divided by 8 times 10⁷, subtract exponents to get 2.4 times 10⁶, or adjust the numerator and divide by 8 to find 3 times 10⁵ as the result to perform the calculation mentally.

Explanation:

When dealing with the division of expressions involving powers of ten, using exponent subtraction is often useful to simplify the problem. For the expression 2.4 times 10¹³ divided by 8 times 10⁷, one approach is to directly subtract the lower exponent from the higher one, yielding 2.4 times 10¹³⁻⁷, which simplifies to 2.4 times 10⁶. However, to perform in my head, an alternative way is to adjust the numerator by dividing it by 8, which results in 0.3 times 10¹³. Moving the decimal point in the numerator gives 3 times 10¹², and then dividing by 10⁷ gives a final result of 3 times 10⁵.

Given the functions f(x) = 3x2, g(x) = x2 - 4x + 5, and h(x) = -2x2 + 4x + 1, rank them from least to greatest based on their axis of symmetry.


f(x), g(x), h(x)

f(x), h(x), g(x)

g(x), h(x), f(x)

g(x), f(x), h(x)

Answers

Answer:

If we rant their axis of symmetry from least to greatest, it would be:

f(x),h(x), g(x)

Step-by-step explanation:

Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror like reflection of either side of the object.

We can find axis of symmetry with the help of formula:

x = -b/2a

We know that the quadratic equation is written like:

ax^2+bx+c

where a,b are coefficients: c is constant term and x is variable

Now look at the function f(x)= 3x^2

For this function we have a= 3, b =0 , c=0

Put the values in the above mentioned formula:

x = -b/2a

x = - (0)/2(3)

x = 0/6 = 0

Thus the axis of symmetry for f(x) = 0

Now  g(x) = x2 - 4x + 5

a = 1 , b = -4 , c =5

x = -b/2a

x = -(-4)/2(1)

x = 4/2

x = 2

Axis of symmetry for g(x) = 2

h(x) = -2x2 + 4x + 1

a = -2 , b =4 , c=1

x = -b/2a

x = -(4)/2 (-2)

x = -4 /-4

x = 1

Axis of symmetry for h(x) = 1

So if we rant their axis of symmetry from least to greatest, it would be:

f(x),h(x), g(x)

A recipe uses 5 cups of water, 3 cups of rice, and 1 cup of black beans. What is the ratio of cups of rice to cups of water?

Answers

I believe it is 5:3:1. I'm not completely sure, but that's what I think it is.

The ratio of cups of rice to cups of water in the recipe is 3:5, as there are 3 cups of rice for every 5 cups of water.

To find the ratio of cups of rice to cups of water from the recipe that calls for 5 cups of water and 3 cups of rice, you can simply compare the two quantities directly. The question asked does not require considering additional batches or conversions, so we look at the given amounts.

For every 3 cups of rice, there are 5 cups of water. This can be written as 3:5 or as a fraction \\(\frac{3}{5}\\).

Therefore, the ratio of cups of rice to cups of water is 3:5.

You work for a landscaper that has a customer needing to seed an area of land 80 feet by 40 feet in size. The garden center
has 5-pound bags of grass seed. Each bag of seed costs $3.00 and can cover 25 square yards of land.
To determine the cost of materials, you multiply 80 x 40 = 3200, divide by 9 = 355.55 and then multiply by 3. The cost of
materials will be $1067. Is this correct?

Answers

Final answer:

The correct calculation for the total cost to seed an area of 80 feet by 40 feet is $45.00, substantially less than the incorrect $1067 identified due to proper area conversion and cost calculation.

Explanation:

The question about the cost of seeding an area of 80 feet by 40 feet involves calculations for area conversion, determining the number of seeds needed, and calculating the total cost. The initial step involves calculating the area in square feet (80 x 40 = 3200 sq ft) and then converting this area into square yards by dividing by 9 (since there are 9 sq ft in a sq yd), which equals approximately 355.56 sq yds. The bags of grass seed required is then determined by the coverage rate of 1 bag per 25 square yards, yielding about 14.22 bags. However, since you cannot purchase a fraction of a bag, you would need to buy 15 bags of seeds. At a cost of $3.00 per bag, the total cost is $45.00, contrasting significantly with the incorrect calculation provided in the question.

far did he ride?

Answers

Answer:

45 Miles

Step-by-step explanation:

Speed = Distance / Time

Distance = Speed * Time

= 7.5 * 6 = 45 Miles

Final answer:

To find the distance traveled by the bicycle rider, multiply the average speed of 7.5 mph by the time of travel of 6 hours, resulting in a total distance of 45 miles.

Explanation:

Calculating Distance Traveled

To calculate the distance traveled by the bicycle rider, we use the formula that relates average speed, distance traveled, and time of travel:

Average speed = Distance traveled / Time of travel

In this scenario, the bicycle rider's average speed is given as 7.5 mph, and the time of travel is 6 hours. Therefore, the distance traveled can be calculated by multiplying the average speed by the time of travel:

Distance traveled = Average speed × Time of travel

Distance traveled = 7.5 mph × 6 h = 45 miles

Therefore, the bicycle rider traveled a total of 45 miles.

Final answer:

The equation of the line that passes through the points (8,1) and (2,-5) in standard form is 2x - 3y = 13.

Explanation:

To find the equation of the line that passes through the given points we need to understand the slope (rise over run) and the y-intercept. The provided equation, y + 1 = 2/3(x - 8), is in point-slope form (which is y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line). To transform to the standard form, we distribute the 2/3 on the right side, subtract 1 from both sides to move y to the left side.

Following these steps, we get: 2x - 3y = 13, as the equation of the line in the standard form.
