Step-by-step explanation:

the answer is addition because if you add those they just its 12 cause thats 3x4 but if its 3 by 3 four times thats 81 and 3 to the fourth power thats 81 and last 3 squared twice multiplied by each other is 81

Hope this explains it im not very good at explanations but i tried lol

Use the formula d = rt to ﬁnd the distance, rate, or time

Varvara68 [4.7K]

Answer:

16. d = distance

r = rate

t = time.

We know that the rate = 4, and time = 11.

=> d = 4 * 11

=> d = 44

17. We know that distance = 36, and time = 4.

=> 36 * r* 4

=> 36 = 4r

=> 36/4 = 4r/4

=> r = 9

What is the mass of an object that has a density of 1.3 g/cm3 and a volume

tangare [24]

Answer:

The mass of the object is 2.6 grams

Step-by-step explanation:

The density of an object is the ratio between its mass and its volume

The equation of the is d = $\frac{m}{V}$ , where

m is the mass

V is the volume

Let us use this equation to solve the question

∵ An object has a density of 1.3 g/cm³

∴ d = 1.3 g/cm³

∵ Its volume is 2 cm³

∴ V = 2 cm³

→ Substitute them in the equation of the denisty above

∵ 1.3 = $\frac{m}{2}$

→ Multiply both sides by 2

∴ 2 × 1.3 = 2 × $\frac{m}{2}$

∴ 2.6 = m

∴ The mass of the object is 2.6 grams

The roots of the equation are 3 + 8i and 3 – 8i.

g100num [7]

Given that the roots of the equation x^2-6x+c=0 are 3+8i and 3-8i, the value of c can be obtained as follows;
taking x=3+8i and substituting it in our equation we get:
(3+8i)^2-6(3+8i)+c=0
-55+48i-18-48i+c=0
collecting the like terms we get:
-55-18+48i-48i+c=0
-73+c=0
c=73
the answer is c=73
