mario62 [17]2 years ago
4 0

Step-by-step explanation:

40 increases to 56.

<u>To find the percent increase:</u>

Subtract the increased value from the original value.

Divide the difference by the original value.

Multiply the quotient by 100 to represent the percent.

<u>Solve:</u>

56 - 40 = 16

16 \div 40 = 0.4

0.4 \times 100 = 40

There's a 40% increase.

Can someone help out I’m really slow at this and don’t understand it please:)
myrzilka [38]

Answer:

2) 160

3) 320

Step-by-step explanation:

you want to find out the slope so use the formula

y₂-y₁/ x₂-x₁ and plug in the numbers

320-80=240

4-1=3

divide 240/3= 80

multiply 80 * (x) so if we try and find x=2 it would be 160

80 * 3 = 240

check your work by multiplying 80 and 4 (320) which is your y value! hope this helps!

WILL MARK BRAINLIEST IF CORRECT❤️❤️<br> Simplify the expression -5+i/2i<br> Step by step
zhenek [66]

Answer:

For complex numbers,

a + bi and a - bi

they have the interesting property that if you add them you get the real number 2a

and if you multiply them , because of the difference of square pattern, you get a^2 - b^2 i^2

But since i^2 = -1, we end up with a real number as a product.

e.g. 6 - 5i and 6 + 5i are conjugates of each other

sum = 6-5i + 6+5i = 12

product = 36 - 25i^2

= 36 -(-25) = 61

Your question is even easier, since the denominator is a monomial instead of a binomial, so we just have to multiply by i/i

Also I believe, according to the answer, that you have a typo, and you meant

(-5+i)/(2i)

= (-5+i)/(2i) *i/i

= (-5i + i^2)/2i^2)

= (-5i +i^2)/-2

= (-5i - 1)/-2

= (1 + 5i)/2 or they way they have it: 1/2 + 5i/2

C(n) = 4/9(-3)^n-1<br> What is the 3rd term in the sequence?
Yanka [14]

Step-by-step explanation:

c(n) =  \frac{4}{9} ( - 3)^{n - 1}   \\   \\  \therefore \: c(3) =  \frac{4}{9} ( - 3)^{3- 1}   \\   \\  \therefore \: c(3) =  \frac{4}{9} ( - 3)^{2}   \\   \\  \therefore \: c(3) =  \frac{4}{9}  \times 9   \\   \\   \huge{ \purple{ \boxed{\therefore \: c(3) = 4}}}
