The value of the expression is -0.01

'In algebra, a decimal number can be defined as a number whose whole number part and the fractional part is separated by a decimal point.'

According to the given problem,

⇒ [tex]-\frac{1}{1000} *100*(-\frac{1}{100} )*(-10)[/tex]

⇒ -0.01

Hence, we can conclude, the value of the expression is -0.01.

Answer:

The function y = 5 [tex](.98)^{x}[/tex] represents exponential decay

The percentage rate of change is 2%

Step-by-step explanation:

The formula of the exponential growth is y = a [tex](1+r)^{x}[/tex], where

The formula of the exponential decay is y = a [tex](1-r)^{x}[/tex], where

Let us solve the question.

∵ y = 5 [tex](.98)^{x}[/tex]

→ Compare it with the forms above

∴ a = 5

∵ The rate of change is .98

∵ .98  < 1

→ That means the rate of change is decreasing

∴ The function y = 5 [tex](.98)^{x}[/tex] represents exponential decay

→ From the 2nd form above

∵ (1 - r ) = .98

→ Subtract 1 from both sides

∴ 1 - 1 - r = .98 - 1

∴ - r = - .02

→ Divide both sides by -1

∴ r = .02

→ Multiply it by 100% to change it to a percentage

∵ .02 × 100% = 2%

∴ r = 2%

∴ The percentage rate of change is 2%

Answer: -2

Step-by-step explanation:

So basically I located the y-intercept first. Where is that? At the point (0,-2). Now from there, I found the nearest point on an intersecting grid line, in this case it would be (-1,0). So from the y-intercept, I looked at how many spaces I would have to move to get to (-1,0). You would have to go up 2 spaces and to the left 1 space. This is also written as 2/-1. Simplify this and you get -2! Hope this helped!

Answer:

The values of x and y are x = 5 and y = -13 ⇒ B

Step-by-step explanation:

If the complex numbers are A = (a + bi) and B = (c + di), then

A + B = (a + c) + (b + d)i

Let us solve the question

∵ (x + yi) + (4 + 9i) = 9 - 4i

→ Add the real parts and the imaginary parts on the left side

∵ x, 4 are the real parts, and y and 9 are the imaginary parts

∴ (x + 4) + (y + 9)i = 9 - 4i

→ Compare the two sides, and equate the like terms

∵ 9 is the real part and -4 is the imaginary part

∴ x + 4 = 9

→ Subtract 4 from both sides

∴ x + 4 - 4 = 9 - 4

∴ x = 5

∵ y + 9 = -4

→ Subtract 9 from both sides

∵ y + 9 - 9 = - 4 - 9

∴ y = -13

Answer:

x = 5 and y = -13

the answer is 3

Step-by-step explanation:

There are 3 number of items must be sold in order for the supply and demand to be equal.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

An economic model predicts that the supply, s, and the demand, d, for a new product can be estimated using the lines on the graph.

Now,

In the graph, The two line intersect at a point (3, 48).

So, We can say that;

There are 3 number of items must be sold in order for the supply and demand to be equal.

Thus, There are 3 number of items must be sold in order for the supply and demand to be equal.

Answer:

40 bars

Step-by-step explanation:

Where x = Number of bars purchased by each team

We solve this question by equating both Equations from Company A to Company B

Company A = Company B

0.75x = 10 + 0.50x

Collect like terms

0.75x - 0.50x = 10

0.25x = 10

x = 10/0.25

x = 40 bars

Hence, each team need to purchase 40 bars from each company

Answer:

Perimeter: 52 Area: 181-16i?

Step-by-step explanation:

Perimeter

The formula for perimeter is 2l+2w, so you plug in the binomials they give you:

2(11-4i)+2(15+4i)

expand:

22-8i+30+8i

combine like terms (which cancels out 8i and -8i):

22+30=52

Area

"i" is not a real number and thus should not be part of the area here, meaning this answer as it is is wrong and I don't know how one would change that.

Here's what I did to get 181-16i, in any case:

The formula for area is l*w, so I plugged in the numbers:

(11-4i)(15+4i)

expanded:

165+44i-60i-16i*i

and combined like terms:

181-16i

*i is [tex]\sqrt{-1}[/tex], so [tex]i^{2}[/tex]=-1 and -1*-16=16.

Answer:

8

Step-by-step explanation:

X=56÷7=8

By moving 7 to other side

And change the sign to divide

Becz if it multiplication it will change to divide and if plus it will change it sign to negative

The value of x in the equation 7x = 56 is 8.

To solve the equation 7x = 56 for x, we can isolate x by dividing both sides of the equation by 7.

7x/7 = 56/7

Simplifying:

x = 8

Therefore, x is equal to 8.
