A 12 foot ladder leans against a building. The angle of elevation from the ground to the foot of the ladder is 46°. Find, to the nearest tenth of a foot, how far is the foot of the ladder from the building
Answer:
8.3 ft
Step-by-step explanation:
Hypotenuse is the longest side
Opposite is the side opposite the angle
Adjacent is the remaining side
Draw the triangle out, and you'll find that the hypotenuse (length of ladder) is 12ft, and that you are looking for the adjacent side (length of the foot of the ladder to the building). Rule out the opposite side (side of building) as it is not needed. The appropriate trigonometric formula is then the [tex]cos(angle) = \frac{adjacent}{hypotenuse}[/tex], rearranged to find the adjacent side is [tex]adjacent = cos(angle)*hypotenuse[/tex]
substitute the values in and you get cos(46) x 12 = 8.335900446
Solve the quadratic equation 2x2 = 5x + 9. <33 please besties
Answer:x=-1
Step-by-step explanation:
Fill in values for the table using the function
Answer/Step-by-step explanation:
Given:
f(x) = -3x + 4
✔️First row, find x when f(x) = 4:
Substitute f(x) = 4 into the equation
4 = -3x + 4
4 - 4 = -3x
0 = -3x
Divide both sides by -3
0/-3 = x
x = 0
✔️ Second row, find f(x) when x = -1:
Substitute x = -1 into the equation
f(-1) = -3(-1) + 4
f(-1) = 3 + 4
f(-1) = 7
✔️ Third row, find f(x) when x = 1:
Substitute x = 1 into the equation
f(1) = -3(1) + 4
f(1) = -3 + 4
f(1) = 1
✔️ Fourth row, find x when f(x) = 9:
Substitute f(x) = 9 into the equation
9 = -3x + 4
9 - 4 = -3x
5 = -3x
Divide both sides by -3
5/-3 = x
x = -⁵/3

What is this number in standard form? (5×1,000)+(9×1)+(2×1/10)+(6×1/1,000)
Answer:
5009.206
Step-by-step explanation:
The answer is 5009.206. We see that the first portion of this question asks, "(5×1,000)+(9×1)". 5x1000 is 5000. 9x1 is 9. 5000+9= 5009. The second portion of this question asks for the numbers that go after the decimal. 2x1/10 is 2/10. 6x1/1000 is 6/1000. The decimal place stands for one. So we do .206. If the decimal stands for ones that means in this case the 2 is in the tenths place (like it should be since the question asks for 2/10) and the 6 is in the 1000 place (like it should be since the question asks for 6/1000). We add this up together and our answer is 5009.206. Hope this explanation helps! Happy learning!

You are surveying students to find out their opinion of the quality of food served in the school cafeteria. Which of the following samples would be random?
Answer:
aint random
Step-by-step explanation:
The sample is not random. For being a random sample opinion of all the students must be taken whether they are eating hot lunch or not.
What is a Random Sample?A random sample is a subset of a statistical population where "each subset member has the same probability of being picked". A random sample is meant to accurately reflect a group of people.
Random sampling is used in science to conduct blinded studies or randomized control testing.
This sample cannot be called a random sample. This is because a "random sample is an unbiased representation of the group and here we have not taken the opinions of the students who don’t eat hot lunch". So this sample can’t be a random one.

9. The sum of 10 and 7 times a number is 59. What is the
number? (Use n as the variable.)
Answer:
7Step-by-step explanation:
Let,
The number be = n
According to the question,
First 7 times of n = 7n
Sum of 10 and the number = 7n + 10
Said that,
The sum of 10 and 7 times of the number is 59.
Therefore,
By the problem ,
=> 7n + 10 = 59
=> 7n = 59 - 10
=> 7n = 49
[tex] = > n = \frac{49}{7} [/tex]
=> n = 7
Hence,
The required number is 7 (Ans)
The radius of a cylindrical construction pipe is 1.5 ft. If the pipe is 17 ft long, what is the volume?
Use the value 3.14 for π and round your answer to the nearest whole number.
Answer:
120.105 square feet.
Step-by-step explanation:
Given that the radius of a cylindrical construction pipe is 1.5 ft, to determine its volume, given that the pipe is 17 ft long, the following calculation must be performed, knowing that the volume of a cylinder arises from multiplying the number pi by the radius at square of the cylinder, and that result by the height of it:
(3.14 x (1.5^2)) x 17 = X
(3.14 x 2.25) x 17 = X
7.065 x 17 = X
120.105 = X
Thus, the volume of the cylinder is 120.105 square feet.

For the function g(x) = 10 VX-2, what is the inverse function?
o pr}(X) = 7+2
O q'(x) = -2
O 0760) = (+)+2
O 011(x) = (+) --
Answer:
[tex]g'(x) = \frac{x^2}{100} +2[/tex]
Step-by-step explanation:
Given
[tex]g(x) = 10\sqrt{x - 2[/tex]
Required
Determine the inverse function
[tex]g(x) = 10\sqrt{x - 2[/tex]
Replace g(x) with y
[tex]y = 10\sqrt{x -2[/tex]
Swap the positions of x and y
[tex]x = 10\sqrt{y -2[/tex]
Divide through by 10
[tex]\frac{x}{10} = \sqrt{y - 2[/tex]
Square of both sides
[tex]\frac{x^2}{100} = y - 2[/tex]
Make y the subject
[tex]y = \frac{x^2}{100} +2[/tex]
Replace y with g'(x)
[tex]g'(x) = \frac{x^2}{100} +2[/tex]
Hence, the inverse function is: [tex]g'(x) = \frac{x^2}{100} +2[/tex]
Complete the equation of this circle :
Answer:
-2 , 4 , 36Step-by-step explanation:
[tex](x - -2)^{2} + (y - 4)^{2}[/tex]
[tex](x + 2)^{2} + (y - 4)^{2} =36[/tex]
The equation of the circle with a radius of 6 and center (-3, 4) is (x + 3)² + (y - 4)² = 36.
The equation of a circle with radius r and center (h, k) is given by:
(x - h)² + (y - k)² = r²
Radius (r) = 6
Center (h, k) = (-3, 4)
Plugging these values into the equation, we have:
(x - (-3))² + (y - 4)² = 6²
(x + 3)² + (y - 4)² = 36
Therefore, the equation of the circle with a radius of 6 and center (-3, 4) is (x + 3)² + (y - 4)² = 36.

The solution is Option A.
The equation of line is y = 0.25x + 1.5 , where the slope m = 0.25
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )

y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
The initial length of the baby fish is b = 1.5 cm
The baby fish grew at a rate of 0.25 centimeter per week
