What are the values of a and b in the equation (4x^a)^b = 256/x^8
Answers
(4x^-2)^4
= 4^4 x^-8
= 4^4 / x^8
= 256/x^8
Answer:
The value of a is -2 and the value of b is 4.
Step-by-step explanation:
Given expression is,
[tex](4x^a)^b = \frac{256}{x^8}[/tex]
Using [tex](ab)^m=a^m.b^n[/tex] on left side,
[tex]4^b(x)^{ab}=\frac{4^4}{x^8}[/tex] ( [tex]4^4 = 256[/tex] )
Using [tex]a^m=\frac{1}{a^{-m}}[/tex],
[tex]4^b(x)^{ab}=4^4 (x)^{-8}[/tex]
By comparing both sides,
We get,
b = 4 and ab = -8
⇒ a = -2
Hence, the value of a is -2 and the value of b is 4.

Find the area of a triangle with a base length of 3 units and a height of 4 units.
Answers
So these are given so we plug them in
A=1/2(3)(4)
A=6 units
To find the area of a triangle, we need to multiply the base and the height of the triangle and divide the product by 2.
So, the expression we would use to solve this is (3 * 4) / 2.
Let's solve:
(3 * 4) / 2
= 12 / 2
= 6
So, the area of the triangle is 6 units squared.

what is the sum of

5a - 4a = a
Then you would multiply 2 by a, which would equal 2a.
Finally, combine all like terms (all terms with a), to get 8a. (2a + 6a = 8a)

△ABC is similar to △RST . In addition, m∠C=76° and m∠S=3(m∠A) . What is m∠A ? Enter your answer in the box.
Answers
Answer:
∠A = 26°
Explanation:
If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are similar. In case of similar triangle, corresponding angles are congruent.
Angle ∠C = 76
So, ∠T = 76 because of corresponding angle.
Given that,
m∠S=3(m∠A)
We know that,
∠S ≅ ∠B
That means ∠B = 3 (∠A)
Sum of angles in a triangle = 180°
∠A + ∠B + ∠C = 180°
∠A + 3∠A + 76° = 180°
4∠A = 180° - 76°
4∠A = 104°
∠A = [tex] \frac{104}{4} [/tex]
∠A = 26°

The answer is _____
Answers
Mom = 34 years old
Let the number of years be x when Sara will be twice as young as her mom will be.
2(8 + x) = 34 + x

What’s the value of x worth 15 points!

Opposite angles of a parallelogram are equal. You get a hint of that from the 2 acute angles which are both 2x.
Add 15 to both sides.
3x = 2x + 24 + 15
3x = 2x + 39 Subtract 2x from both sides.
3x - 2x = 39
x = 39
Hi there! :)
Answer:
x=39
*The answer must have a positive sign.*
Step-by-step explanation:
When the 2 acute angles in which means you had to used 2x from both sides of an equation.
First, only had to do is, add by 15 from both sides of an equation.
[tex]3x-15+15=2x+24+15[/tex]
Then, you add by the numbers from left to right.
[tex]24+15=39[/tex]
[tex]3x=2x+39[/tex]
Next, you subtract by 2x from both sides of an equation.
[tex]3x-2x=2x+39-2x[/tex]
Finally, you simplify.
[tex]x=39[/tex]
Final answer is x=39

What would be the side length of the smallest square plate on which a 40-cm chopstick can fit along a diagonal without any overhang? (Correct answer will get reward)
Answers
The side length of the smallest square plate required to fit a 40-cm chopstick along its diagonal without any overhang is approximately 28.284 cm.
To find the side length of the smallest square plate in which a 40-cm chopstick can fit along a diagonal without any overhang, we can use the Pythagorean theorem. The diagonal of a square is the hypotenuse of a right-angled triangle formed by two sides of the square. Since the sides of the square are equal, if one side is s, then the diagonal d can be calculated using the equation d = s√2, where √2 is the square root of 2 (approximately 1.4142).
Therefore, to fit a 40-cm chopstick along the diagonal:
Let d = 40 cm.
Use the equation s√2 = 40 cm to find s, the side of the square.
s = 40 cm / √2.
s ≈ 28.284 cm when rounded to three decimal places.
So, the side length of the smallest square plate on which a 40-cm chopstick can fit along a diagonal without any overhang is approximately 28.284 cm.

We have then:
f (x) = 175 * (2 ^ x)
Then, you should know that 1 year contains 12 months.

f (12) = 716800

Simplify these algebraic expressions: 12x + 3 − 4x + 7, 8 − 7x − 13 + 2x, −3x − 18 + 5x − 2
Answers
8-7x-13+2x=-5-5x
-3x-18+5x-2=-16x-2
The simplified expressions are:
12x + 3 − 4x + 7 = 8x + 10
8 − 7x − 13 + 2x = −5x − 5
−3x − 18 + 5x − 2 = 2x − 20
What is an expression?A term is a single mathematical phrase. It might consist of only one variable—a letter—one number—positive or negative—or several variables multiplied but never added or subtracted. A number is placed in front of some nouns that have variables. Coefficients are numbers that come before phrases.
To simplify each expression, we combine like terms:
Expression 1:
12x + 3 − 4x + 7 = (12x − 4x) + (3 + 7)
12x + 3 − 4x + 7 = 8x + 10
Expression 2:
8 − 7x − 13 + 2x = (−7x + 2x) + (8 − 13) = −5x − 5
Expression 3:
−3x − 18 + 5x − 2 = (−3x + 5x) + (−18 − 2) = 2x − 20.
Therefore, the simplified expressions are:
12x + 3 − 4x + 7 = 8x + 10
8 − 7x − 13 + 2x = −5x − 5
−3x − 18 + 5x − 2 = 2x − 20

ASAP Plz what is the value of x? Plz no joking around this is from quiz 4.09: Special Right Triangles 2
Answers
Firstly, let's find RT so that we can solve the top triangle.
We could actually use 3 methods to find this side: 1) trig to find RT
2) trig to find ST, then Pythagorean Theorem to determine RT
3) use the special 30-60-90 right triangle rule ... hmm, I'm going with the last because it's easiest ;)
For 30-60-90 triangles, the sides are always as follows: smallest side (opposite the 30) is s, the middle side is sSR3, and the hypotenuse is 2×s
Thus, since we have the side opposite 60, it is = sSR3, so:
[tex]s \sqrt{3} = 2 \sqrt{3} \\ s \sqrt{3} \div \sqrt{3} = 2 \sqrt{3} \div \sqrt{3} \\ s = 2[/tex]
So now, the hypotenuse (RT) = 2s = 2(2) = 4
Secondly, we are looking at the other type of special right triangle, the 45-45-90:
The side opposite the 45s are s (remember side lengths are equal whose opposite angles are equal); and the hypotenuse is always
[tex]s \sqrt{2} [/tex]
we only need QR, which is s, which is also = RT
So the answer is:
QR = x = 4
x = 4 IS THE FINAL ANSWER!!!
