Answer:
To find the value of log1000, you can use the logarithmic property that states that log(a^b) = b * log(a). In this case, we can rewrite 1000 as 10^3, so log1000 = log(10^3) = 3 * log(10) = 3.

. Which function correctly shows integer values for h and k?
The function that correctly shows the value of k and h is g(x) = 12(x - 5)² - 7
How to determine the function correctly?From the question, we have the following parameters that can be used in our computation:
f(x) = 12(x + 6)² - 3
The transformation is given as
11 units to the right and 4 units down
This is represented as
(x - 11, y - 4)
So, we have the following representation
g(x) = 12(x + 6 - 11)² - 3 - 4

1. The weight for 18 tablespoons is 1127.32 grams.
2. The number of tablespoons of the liquid noah needs to add so that the total weight is 1,200 grams is 23 tablespoon.
What is the weight when 18 tablespoons on the liquid are placed in the bowl?It's vital to note that an equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario.
From the information, Noah placed an empty bowl on a scale and the equation is given as:.
y = 14.75x + 861.82
x = the amount of the liquid, in tablespoons
y = the total weight
The weight for 18 tablespoons will be:
y = 14.75x + 861.82
y = 14.75(18) + 861.82
y = 1127.32
The liquid that Noah needs to add so that the total weight is 1,200 gram will be:
y = 14.75x + 861.82
14.75x + 861.82 = 1200
Collect like terms
14.75x = 1200 - 861.82
14.75x = 338.18

What is a slope?
A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).
The slope-intercept form of an equation is used to represent each time the equation of a line is stated as y = mx + b.
M represents the line's slope. Additionally, b is the b in the y-intercepting point (0, b). For instance, the y-intercept is at (0, 7) and the slope is 3 in the equation y = 3x - 7.

a special window has the shape of a rectangle surmounted by an equilateral triangle. see the figure. if the perimeter of the window is 16 feet, what dimensions will admit the most light?
A triangle whose sides are all equal is called an equilateral triangle and its area is given by A=[tex]\frac{\sqrt{3} }{4}[/tex] [tex]x^{2}[/tex], where x is the side of the triangle.
The area of a rectangle is found by using the formula
A=lw, where l is the length and w is the width.
The given figure can be split into two shapes: a rectangle and an equilateral triangle as shown in the diagram. Let l be the length of the rectangle.
Add all of the sides of the window and equate their result to 16. Then solve for l.
x + x + l + x + l = 16
3x + 2l = 16
2l = 16 - 3x
l = [tex]\frac{16-3x}{2}[/tex]
The total area of the window will be the sum of the area of the equilateral triangle ABE and the area of rectangle BCDE.
A = [tex]\frac{\sqrt{3} }{4}[/tex][tex]x^{2}[/tex] + lx
Subsitute [tex]\frac{16-3x}{2}[/tex] for l into the obtained equation and simplify.
A =[tex]\frac{\sqrt{3} }{4}[/tex][tex]x^{2}[/tex] + ( [tex]\frac{16-3x}{2}[/tex])x
A = [tex]\frac{\sqrt{3} }{4} x^{2}[/tex] + 8x - [tex]\frac{3}{2} x^{2}[/tex]
Differentiate the obtained equation with respect to x and equate the first derivative to 0 to calculate the critical point x .
[tex]\frac{dA}{dx}[/tex] = [tex]\frac{\sqrt{3} }{4}[/tex] (2x) + 8 - [tex]\frac{3}{2}[/tex] (2x)
0 = [tex]\frac{\sqrt{3} }{2}[/tex] x - 3x + 8
x (3 - [tex]\frac{\sqrt{3} }{2}[/tex]) = 8
x = [tex]\frac{16}{6-\sqrt{3} }[/tex]≈3.74887
Again, differentiate the equation
[tex]\frac{dA}{dx}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex]x - 3x + 8 with respect to x.
[tex]\frac{d^{2}A }{dx^{2} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] - 3
The value of the second derivative is [tex]\frac{\sqrt{3} }{2}[/tex]−3, which is negative. This implies that the area will be maximum at the critical point.
Subsitute x = 3.74887 into the equation
l = [tex]\frac{16-3x}{2}[/tex] and simplify
l = [tex]\frac{16-(3)(.74887)}{2}[/tex] ≈ 2.3767
The maximum light will enter through the window when the triangular portion will have the side length of 3.74887 feet and the dimensions of the rectangular portion will be 3.74887-ft-by-2.3767-ft.

Answer:

Step-by-step explanation:
You want the value of y in the diagram showing y as the angle at the base where the isosceles triangle a.pex angle bisector meets the base.
Angle sum theoremThe angle sum theorem tells you the sum of angles in a triangle is 180°.
Consider the large outside triangle. The sum of its angles is ...
60° +2x +60° = 180°
2x = 60° . . . . . . . . . . . . subtract 120°
x = 30° . . . . . . . . . . divide by 2
Now, consider the left smaller triangle. The sum of its angles is ...
60° +x +y = 180°
60° +30° +y = 180° . . . . . . use the known value of x
y = 90° . . . . . . . . . . . . subtract 90°

Additional comment
The a.pex angle bisector of an isosceles triangle is always an altitude that meets the base at right angles. The meeting point is the midpoint of the base, so that segment is also a median.
The halves of the isosceles triangle are congruent right triangles, so the base angle is complementary to the angle marked x.

9, 3, and 1 are the values of a, b, and c using the exponential function g(x)=(1/3)∧x.
What are exponential functions?A mathematical function with the formula f (x) = an x is an exponential function.
Where x is a variable, and an is a constant called the basis of the function.
The most typically seen exponential-function base is the transcendental number e, which is equivalent to about 2.71828.
So, the exponential function:
g(x) = (1/3)∧x
From the table, we are also to find out the value of a, b and c
If x = -2
g(-2) = a = (1/3)⁻²
a = 1/3⁻²
a = 9
Accordingly,
If x = -1
g(-1) = b = (1/3)⁻¹
a = 1/3⁻¹
b = 3
Hence,
If x = 0
If x = -1
g(0) = c = (1/3)⁰
c = 1
Therefore, 9, 3, and 1 are the values of a, b and c using the exponential function g(x) = (1/3)∧x.

Answer:
z = 22
Step-by-step explanation:
Because we are given that angle measures TUW and VUW are the same, we can assume that both triangles are the same since they also have 90 degree angles and both their third angles are equal to 54. (I found that out by taking 180 degrees which is the total angle measure of all triangles, and subtracted it by 90 and 36).
Since they are the same, that means that side TW is the same length as side VW. With this information we can set up an expression:
2z = z + 22
Now, all we have to do is solve for z
2z = z + 22

Ashley is going to invest in an account paying an interest rate of 5.6% compounded continuously. How much would Ashley need to invest, to the nearest dollar, for the value of the account to reach $2,080 in 16 years?
Rounding to the nearest dollar, Ashley would need to invest $1,062 to reach $2,080 in 16 years at an interest rate of 5.6% compounded continuously.
How can you figure out compound interest in mathematics?Compound interest (CI) is calculated as CI = P(1 + r/100)n - P. To calculate the compound interest value, first compute the amount and then deduct the principal from it.
To find the amount Ashley needs to invest, we can use the formula for continuously compounded interest:
A = P * e^(rt)
where A is the final amount, P is the principal (the initial investment), r is the interest rate, and t is the time in years.
We know that A = $2,080 and r = 5.6% = 0.056, and we want to solve for P. We can rearrange the formula to solve for P:
P = A / e^(rt)
Plugging in the values, we get:
P = $2,080 / e^(0.056 * 16)
The value of e^(0.056 * 16) can be calculated using a calculator or computer, and it is approximately 1.96. Plugging this in, we get:
P = $2,080 / 1.96 = $1062.24

How can I solve this ? What is the angle whose tangent is 456/321?
The angle whose tangent is 456/321 is 54.85°
The tangent of an angle in trigonometry is the ratio of the lengths of the adjacent side to the opposing side. In order for the value of the cosine function to not be 0, it is the ratio of the sine and cosine functions of an acute angle.
The Tangent Formula is given as:
Tan A = Opposite Side/Adjacent side
In terms of sine and cosine, tangent may be represented as:
Tan A = Sin A / Cos A
We know that the sine of an angle is equal to the length of the opposite side divided by the length of the hypotenuse side whereas the cosine of the angle is the ratio of the length of the adjacent side to the ratio of the hypotenuse side.
That is, Sin A = Opposite Side/ Hypotenuse Side
Cos A = Adjacent Side/ Hypotenuse Side
Therefore, tan A = Opposite Side/ Adjacent Side
