A 25ft ladder is leaning up against a
wall. If the ladder makes a 63° with
the ground, how far is the base of the
ladder from the wall?
Step-by-step explanation:
A
C H
Cos(23)×25 = 23.0126
The distance of the base of the ladder from the wall is 23.01 ft
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
We are solving from how far the base of the ladder from the wall and we are representing it as x.
Based on the type of triangle, we are going to use Trigonometry ratios.
We are going to use the cos ratio.
Let opposite be x, base be 25 and theta (angle) be 23.
Cos(23) = x/ 25
Make x the subject;
x = Cos(23)×25
x = 23.0126 ft
Therefore the distance is 23.01 ft

Step-by-step explanation:
We want to evaluate
b - (-1/8) + c
where b = 2 and c = -7/4
First, replace b and c values into the expression
2 - (-1/8) + (-7/4)
Then, eliminate the parenthesis
2 + 1/8 - 7/4
Finally, express all terms as fractions with the same denominator, and perform the addition and subtraction
2*8/8 + 1/8 - 7/4 * 2/2
16/8 + 1/8 - 14/8

f(x) and g(x) are inverse functions. What is g(f(-4)) equal to?
A.
4
B.
-4
C.
x
D.
1
E.
-1
Answer:
The answer is B -4
Step-by-step explanation:
An inverse function is a function that will “undo” anything that the original function does. For example, if a function takes a to b, then the inverse must take b to a.
Answer:
-4
Step-by-step explanation:
The inverse of a function and the function counteract each other. The are opposites. It is like adding and subtracting the same thing. You end up where you started
Since f(x) and g(x) are inverses
f(g(x) = x
g(f(-4)) = -4

Type the correct answer in each box. Use numerals instead of words. Consider this quadratic equation. x2 + 2x + 7 = 21 The number of positive solutions to this equation is _______ . The approximate value of the greatest solution to the equation, rounded to the nearest hundredth, is _______ .
Answer:
-1 ± 3i√6
Step-by-step explanation:
Please write this quadratic equation as follows: x^2 + 2x + 7 = 21. The " ^ " indicates exponentiation.
The coefficients of this quadratic are 1, 2, 7.
Thus, the "discriminant" b^2 - 4(a)(c) is (2)^2 - 4(1)(7), or 4 - 28, or -24.
Because the discriminant is negative, this quadratic has two different complex roots:
-b ± √[ discriminant ] -2 ± 2i√6
x = --------------------------------- = ----------------- = -1 ± 3i√6

plz solve -8 ( x - 3 ) - 4x = 48
Answer:
x = -2
Step-by-step explanation:
-8 ( x - 3 ) - 4x = 48
Distribute
-8x +24 -4x = 48
Combine like terms
-12x +24 = 48
Subtract 24 from each side
-12x+24-24 = 48-24
-12x = 24
Divide each side by -12
-12x/-12 = 24/-12
x = -2
Answer:
X= -2
Step-by-step explanation:
First, you need to distribute -8 into (x-3) ---> -8(x-3)-4x=48
-8x + 24 -4x= 48
Get numbers with variables on its own side--> -24 -24
-8x - 4x = 24
Combine -8x and -4x -----> -8x-4x = -12x -12x = 24
Divide ----------------------------------> -12 -12
24÷ -12 = -2

Answer:
Think of even square roots close to 27: the closest is 25 which has a square root of 5. Now think of the number with an even square root after 25: 36 which has a square root of 6. Since 27 is between 25 and 36, the square root of 27 would be between 5 and 6.

1.25 = 0.75 + r
What is r ?
r = 0.5
Step-by-step explanation:
[tex]1.25=0.75+5[/tex]
We can subtract 0.75 from both sides. The 0.75 will then cancel out.
[tex]0.5=r[/tex]
r = 0.5
Answer:
r = 0.5
Step-by-step explanation:
1.25= 0.75 + r
r = 1.25- 0.75
r = 0.5

Answer:
[tex](A)\sqrt[6]{k^{-1}}\\(C)\left(k^{-1}\right)^{{1/6}}[/tex]
Step-by-step explanation:
Given the expression [tex]k^{^{-\dfrac{1}{6}}}[/tex] , we apply the following rule of indices to obtain equivalent forms.
Negative Exponent Rule: [tex]a^{-m}=\dfrac{1}{a^m}[/tex]Fractional Exponent Rule: [tex]a^{1/m}=\sqrt[m]{a}[/tex]Therefore:
[tex]k^{-1/6}=(k^{-1})^{1/6}[/tex]
This is Option C,
If we simplify further, we obtain:
[tex]k^{-1/6}=(k^{-1})^{1/6}\\=\sqrt[6]{k^{-1}}[/tex]
This is option A.
Therefore, Options A and C are equivalent to the given expression.
