Helloooo helppp me please

The mantissa of scientific notation or standard form is between 1 and 10 in absolute value, or 1 ≤ |a| < 10.  It can be 1, hence, it does not have to be greater than 1.

Standard form is also called scientific notation and has the form:

a x 10ᵇ

Where b is an integer and is called exponent.

a is a real number between 1 and 10 (in absolute value), it includes 1 but not 10, or we can write a should satisfy 1 ≤ |a| < 10.

Usually, a is called mantissa.

Example:

2467 can be written in standard form as:

2467 = 2.467 x 10³

0.0095 can be written in standard form  as:

0.0095  = 9.5 x 10⁻³

150 x 10² can be written in standard form  as:

150 x 10² =1.5 x 10⁴

-0.062 can be written instandard form  as:

-0.062 = -6.2 x 10⁻²

The least common denominator (LCD) of 3/4 and 5/6 is 12

To discover the least common denominator, list the multiples of both denominators until you find the smallest multiple that both denominators share. Because 20 is the first shared multiple of 4 and 5, it must be the fractions’ least common denominator.

The least common denominator (LCD) of a group of fractions is the least common multiple (LCM) of their denominators.

In this case, the denominators of the fractions are 4 and 6. The least common multiple (LCM) of 4 and 6 is 12. Therefore, the least common denominator of 3/4 and 5/6 is 12.

You can also find the LCM by finding the prime factorization of the numbers, and then take the highest power of each prime factor and then multiply those.

[tex]4 = 2^2\\6 = 2*3[/tex]

The highest power of 2 and 3 are [tex]2^2[/tex] and 3 respectively, so LCM(4,6) = [tex]2^2 * 3 = 12[/tex]

So the LCD of 3/4 and 5/6 is 12.

Answer:

c = 4

Step-by-step explanation:

Solve for c:

2 (c + 1) = 10

Divide both sides of 2 (c + 1) = 10 by 2:

(2 (c + 1))/2 = 10/2

2/2 = 1:

c + 1 = 10/2

The gcd of 10 and 2 is 2, so 10/2 = (2×5)/(2×1) = 2/2×5 = 5:

c + 1 = 5

Subtract 1 from both sides:

c + (1 - 1) = 5 - 1

1 - 1 = 0:

c = 5 - 1

5 - 1 = 4:

Answer: c = 4

Answer:

[tex]\boxed{\sf c=4}[/tex]

Step-by-step explanation:

[tex]\sf 2(c+1)=10[/tex]

Distribute:-

[tex]\sf 2c+2=10[/tex]

Subtract 2 from both sides:-

[tex]\sf 2c+2-2=10-2[/tex]

[tex]\sf 2c=8[/tex]

Divide both sides by 2:-

[tex]\sf \cfrac{2c}{2}=\cfrac{8}{2}[/tex]

In linear equation, The number of pounds of apples is 12 and the number of pounds of raspberries is 20.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                    Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Given that, the cost of a pound of apples = $2.25 and the cost of a pound of raspberries = $1.50.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of pounds of apples be x, then the number of pounds of raspberries(y) be y=x+ 12

Now, the total cost of apples = The number of pounds of apples × The cost of a pound of apples

=x × 1.50

= 1.50x

The total cost of raspberries = The number of pounds of raspberries × The cost of a pound of raspberries

=(x+12) × 3

=3x+ 36

So, the total cost = The total cost of apples + The total cost of raspberries

⇒ 72 = 1.50x+ 3x+ 36

⇒  72 = 4.5x + 36

        4.5x = 72-36

            x =  8

So, y= x+ 12 = 20

Therefore, the number of pounds of apples is 12 and the number of pounds of raspberries is 20.

The solution of the inequality for n is n > 31/40

Inequality is a statement of an order relationship greater than or equal to less than between two numbers or algebraic expressions.

Inequalities are not only driven by and measured by income but are also determined by other factors including gender origin, ethnicity, disability,  class and religion. Moreover inequalities are determined not only by income but also by other factors.

How to solve the inequality?

The inequality is given as

n minus three eighths is greater than negative two fifths

Rewrite properly as

n - 3/8 > 2/5

Add 3/8 to both sides

n > 3/8 + 2/5

Evaluate the sum

n > 31/40

Hence, the solution of the inequality for n is n > 31/40

The

hypotenuse's square

of a right triangle is equal to the sum of its legs' squares.

What is Pythagorean theorem?

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in

Euclidean

geometry.

According to this rule, the areas of the squares on the other two sides add up to the area of the square whose side is the hypotenuse, or the side across from the right angle.

This theorem can be expressed as the Pythagorean equation, which is an equation connecting the lengths of the sides a, b, and the

hypotenuse

c.

There are several ways to generalize the theorem, including to higher-dimensional spaces, non-Euclidean spaces, objects other than right triangles, and even things that are not triangles at all but n-dimensional solids.

Hence, The hypotenuse's square of a right triangle is equal to the sum of its legs' quares.

Answer:

y = -2/3x

Step-by-step explanation:

The graph of the given function is attached below.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

The graph of the function y = -2log2(x+3) + 2 is a downward-sloping curve that approaches the x-axis as x approaches infinity.

The curve is defined only for positive values of x, as the logarithm is undefined for negative values.

As x increases, the logarithm term inside the parentheses becomes larger in magnitude, causing the value of y to decrease rapidly.

The curve approaches the x-axis but never touches it, as the logarithm term will never reach zero.

I think there is a typo in option D. because it says to find the nearest whole number but 4.6 is not a whole number.

The average rate of change of h(x) on the interval [-1, 8] is r = -3.6

For any function, the average rate of change on an interval [a, b] is given by:

r = ( f(b) - f(a))/(b - a)

In this case, the function is:

h(x) = -x^2 + 4x + 12

And we want to find the average rate of change on the interval [-1, 8]

Evaluating the function in these values we will get:

h(-1) = -(-1)^2 + 4*(-1) + 12

h(-1) = -1 - 4 + 12 = 7

h(8) = -(8)^2 + 4*8 + 12 = -20

Then the average rate of change is:

r = ( h(8) - h(-1) )/(8 + 1)

r = (-20 - 12)/9

r = (-32/9) = -3.6

If 4 cm and 7 cm are the lengths of two sides of a triangle then the length of the third side should be 6 cm.

In the given question we have to check 4 cm and 7 cm are the lengths of two sides of a triangle then the length of the third side may be.

Any two sides of a triangle can have a sum of lengths that is always greater than the length of the third side.

Any two triangle sides' length differences will never be greater than the triangle's third side's length.

The sum of 4cm and 7cm is 11cm, and their difference is 3cm.

The third side's possible length must be larger than 3 cm and less than 11 cm to ensure that the aforementioned rule is not broken.

6 cm is therefore larger than 3 cm and less than 11 cm from the possibilities presented.

The midpoint formula is used to calculate elasticity because it overcomes the limitations of the traditional method.

The old point-slope method has significant drawbacks that are overcome by the midpoint formula, which determines the elasticity of demand. The elasticity of demand refers to how sensitively a good's quantity desired is to a price shift. Inelastic goods are those in which a little price shift causes a large change in quantity demanded, while elastic goods are those in which a small drop causes a small change in quantity demanded.

The conventional point-slope formula for elasticity employs the change in quantity and price at a particular point, which might be deceptive in some circumstances. Contrarily, the midpoint formula determines the elasticity of demand by averaging the quantity and price at the beginning and end and utilising the percentage change in both.
