What is the value of y in the product of powers below? 8 cubed times 8 Superscript negative 5 Baseline times 8 Superscript negative 2 Baseline = StartFraction 1 Over 8 squared EndFraction
Answer: [tex]y=0[/tex]
Step-by-step explanation:
The complete exercise is attached.For this exercise it is important to remember:
1. The Product of powers property. This property states that:
[tex](a^m)(a^n)=a^{(m+n)}[/tex]
2. The multiplication of signs:
[tex](+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-[/tex]
Then, given:
[tex]8^3*8^{-5}*8^y=8^{-2}=\frac{1}{8^2}[/tex]
You can identify that [tex]8^{-2}[/tex] is obtained by applying the Product of powers property:
[tex]8^{3+(-5)+y}=8^{-2}=\frac{1}{8^2}[/tex]
Based on the explained above, you can write the following equation:
[tex]3+(-5)+y=-2[/tex]
Therefore you must solve for the variable "y" in order to find its value. You get that this is:
[tex]3-5+y=-2\\\\-2+y=-2\\\\y=-2+2\\\\y=0[/tex]
Answer:
You're trying to find the value of y that would result in 8^-2. When you multiply terms with the same base, you can add the exponents. 3+-5=-2 and -2-(-2) equals 0, so therefore y is equal to 0.

if sin F = 3/5 , what is cos G ?
Answer:
D
Step-by-step explanation:
side HG is 3
side FG is 5 hypotenuse
sin F = 3/5 = opposite/hypotenuse
cos G is adjacent/hypotenuse
adjacent side is HG which = 3
hypotenuse is 5
Without additional context, we cannot give a direct answer for cos G based only on sin F = 3/5. If F and G are complementary angles in a right triangle, cos G would also be 3/5. Otherwise, more information about the relationship between F and G is needed.
Explanation:To solve this question, we need a bit more context because there is not enough information provided to directly determine the value of cos G. However, typically, if sin F is given as 3/5 for a right triangle, then by the Pythagorean theorem, we know cos F = √(1 - sin^2 F), which calculates to 4/5, assuming F is an angle in a right triangle in standard position with F between 0 and 90 degrees.
This doesn't directly give us cos G, but if we assume G is the complementary angle to F in a right triangle (F + G = 90 degrees), then cos G = sin F and we could say cos G is also 3/5. If sine and cosine relate to different triangles or different contexts, we would need the relationship between angles F and G or additional information to solve for cos G.

Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ!
Your equation will be 2x*6=(11*x)-(8/5)
12x=11x-1.6
-11x -11x
x=-1.6
(っ◔◡◔)っ ♥ Hope this helped! Have a great day! :) ♥
The number that satisfies the given condition the product of twice a number and six is the same as the difference of eleven times the number and 8/5 is -1.6.
Let's assume the number we are looking for is "x."
The problem states that the product of twice the number and six is the same as the difference of eleven times the number and 8/5.
Step 1: Express the given statement as an equation.
The product of twice the number and six is 2x * 6 = 12x.
The difference of eleven times the number and 8/5 is 11x - 8/5.
Now, we can set up the equation:
12x = 11x - 8/5
Step 2: Solve for x.
To solve for x, we need to isolate x on one side of the equation. Subtract 11x from both sides of the equation:
12x - 11x = 11x - 11x - 8/5
x = -8/5
The number we are looking for is x = -8/5 or -1.6.

Which of the following is a solution to this inequality? y>1/2x+2
The only solution to the inequality is point A, (1,4). Thus, the correct answer is A. To find the solution to the inequality [tex]\( y > \frac{1}{2}x + 2\),[/tex] we need to determine which of the given points satisfy the inequality. Let's test each point by substituting its coordinates into the inequality and checking if it holds true.
A. (1,4):
When [tex]\(x = 1\)[/tex] and [tex]\(y = 4\),[/tex] we have:
[tex]\(4 > \frac{1}{2}(1) + 2\)[/tex]
[tex]\(4 > \frac{1}{2} + 2\)[/tex]
[tex]\(4 > 2.5\)[/tex]
This is true, so point (1,4) satisfies the inequality.
B. (-1,1):
When [tex]\(x = -1\)[/tex] and [tex]\(y = 1\)[/tex], we have:
[tex]\(1 > \frac{1}{2}(-1) + 2\)[/tex]
[tex]\(1 > -\frac{1}{2} + 2\)[/tex]
[tex]\(1 > 1.5\)[/tex]
This is false, so point (-1,1) does not satisfy the inequality.
C. (2,3):
When [tex]\(x = 2\)[/tex] and [tex]\(y = 3\)[/tex], we have:
[tex]\(3 > \frac{1}{2}(2) + 2\)[/tex]
[tex]\(3 > 1 + 2\)[/tex]
[tex]\(3 > 3\)[/tex]
This is false, so point (2,3) does not satisfy the inequality.
D. (0,2):
When [tex]\(x = 0\)[/tex] and [tex]\(y = 2\)[/tex], we have:
[tex]\(2 > \frac{1}{2}(0) + 2\)[/tex]
[tex]\(2 > 2\)[/tex]
This is false, so point (0,2) does not satisfy the inequality.
Therefore, the only solution to the inequality is point A, (1,4). Thus, the correct answer is A.
The complete question is:
Which of the following is a solution to this inequality? y>1/2x+2
A. (1,4)
B. (-1,1)
C. (2,3)
D. (0,2)
This is the answer to a problem or an equation.
Example: For 3x+6=27, this is x=7
Answer:
x=7 is the answer
3x+6=27 is the equation
x=7 is the correct answer for the equation.
To solve the equation 3x + 6 = 27, subtract 6 from both sides and then divide by 3 to get x = 7. Verify by substituting x = 7 back into the original equation. This confirms the solution is correct by making a true statement.
Step by Step Solution:
When solving an algebraic equation, the goal is to find the value of the variable that makes the equation true. For example, consider the equation 3x + 6 = 27. To solve for x, follow these steps:
Subtract 6 from both sides of the equation: 3x + 6 - 6 = 27 - 6, which simplifies to 3x = 21.
Next, divide both sides by 3: 3x / 3 = 21 / 3, which gives x = 7.
To verify the solution, substitute x = 7 back into the original equation: 3(7) + 6 = 27. Simplifying this, we get 21 + 6 = 27, which is a true statement, verifying our solution.
Note that an identity in algebra is an equation that is true for all values of the variable, such as 6 = 6. In our example, the solution x = 7 makes both sides of the original equation equal, thus satisfying the equation.
a rectangle has a length of 6cm, and an area of 18cm aquared. what is the width of the rectangle?
Answer:
3 cm
Step-by-step explanation:
The formula for the area of a rectangle is ...
A = LW . . . . . . area is the product of length and width
Fill in the given values and solve for the width (W).
18 cm² = (6 cm)W
(18 cm²)/(6 cm) = W = (18/6) cm²/cm . . . . . . divide by the coefficient of W
W = 3 cm
The width of the rectangle is 3 cm.
The width of a rectangle, with a length of 6 cm and an area of 18 cm squared, is 3 cm.
Explanation:The question is asking for the width of a rectangle which we can find using the formula for the area of a rectangle. The formula is: Area = Length x Width. From the given question, we know that the area is 18 cm2 and the length is 6 cm. So, we can set up the equation: 18 = 6 x Width. To solve for width, we divide both sides of the equation by 6. This gives us Width = 18 ÷ 6 which equals 3 cm.

_____ life insurance is for a specific time period and is the cheapest way to buy life insurance.
Term life insurance is insurance that insures you for a certain time period like 5 years for example.
Usually in months and years is how its done.
Term life insurance is for a specific time period and is the cheapest way to buy life insurance.
Unlike permanent life insurance policies, which cover an individual for their entire life, term life insurance offers protection for a predetermined period, such as 10, 20, or 30 years. Because it does not accumulate cash value and only pays out a death benefit if the insured passes away during the specified term, premiums for term life insurance tend to be lower compared to permanent policies.
The affordability of term life insurance makes it an attractive choice for individuals seeking to secure financial protection for their loved ones during specific critical periods, such as the years when children are growing up or when a mortgage is being paid off.
It's a straightforward and efficient way to provide a death benefit for beneficiaries in case the insured passes away within the chosen term, offering financial security without the long-term commitment and higher premiums associated with permanent life insurance options.

The isosceles triangle has a perimeter of 7.5 m.
Which equation can be used to find the value of x if the shortest side, y, measures 2.1 m?
2 x minus 2.1 equals 7.5
4.2 plus y equals 7.5
y minus 4.2 equals 7.5
2.1 plus 2 x equals 7.5
The equation 2.1 plus 2 x equals 7.5 can be used to find the value of x ⇒ 4th answer
Step-by-step explanation:
In an isosceles triangle:
Two sides are equal ⇒ the angle between them is called the vertex angle of the triangleTwo angles are equal ⇒ they called the base angles∵ The triangle is isosceles
- That means it has two equal sides
∵ The shortest side is y
∵ The length of the other two sides is x
∴ The perimeter of the triangle = y + 2 x
∵ The perimeter of the triangle = 7.5 m
- Equate the expression of the perimeter by 7.5
∴ y + 2 x = 7.5
∵ The shortest side measures 2.1 m
∴ y = 2.1
- Substitute y by 2.1 in the equation above
∴ 2.1 + 2 x = 7.5
The equation 2.1 plus 2 x equals 7.5 can be used to find the value of x

Select the correct answer from each drop down menu the cross-section is the intersection of a Solid or point and a plain in line
Answer:
Solid / plane
Step-by-step explanation:
A cross-section is a geometric concept, representing the intersection of a solid and a plane. The shape of the cross-section depends on how the plane intersects with the solid. A related physics concept is the continuity equation which states that the amount of incompressible liquid entering a cross-sectional area must equal the amount leaving it.
Explanation:In mathematical terms, a cross-section is usually the intersection of a 3-dimensional solid with a plane. This concept is often used in Geometry. For instance, if we intersect a cylinder with a plane perpendicular to the base of the cylinder, the cross-section will be a circle which is the same size as the base of the cylinder. On the other hand, if the plane is parallel to the axis of the cylinder, the cross-section would be a rectangle.
A related concept, from the field of Physics, as described in Figure 14.28, is the continuity equation, usually applied when analyzing fluid dynamics. The equation posits that the volume of fluid entering a cross-sectional area of a duct or pipe must equal the volume of fluid leaving it, assuming the fluid is incompressible. This is because the mass of liquid cannot change within a closed system.
