Answer:

53. ±6

51. 2

Step-by-step explanation:

According to the Order of Operations [GEMS\BOMDAS\PEMDAS etc.], in this case, evaluate everything in grouping symbols first, then evaluate the exponents to avoid confusion:

$\sqrt{(32 + {2}^{3} - 4)} = \sqrt{32 + 8 - 4} = \sqrt{36} = ±6 \\ \\ (17 - 11 + {4}^{2}) \div 11 = (17 - 11 + 16) \div 11 = \\ \\ 22 \div 11 = 2$

I am joyous to assist you anytime.

1) Mr. Rios bought a house in 1960 for $20,000. The value of the house increased by

lana [24]

Answer:

A = 20,000(1.05)^x

Step-by-step explanation:

To get the approximate value of the house after x years, we will use the compound interest formula

A = P(1+r)^n

P is the principal = $20,000 (cost of house)

r is the rate = 5% = 0.05

x is the time

Substitute into the expressio

A = 20,000(1+0.05)^x

A = 20,000(1.05)^x

Hence the required expression is A = 20,000(1.05)^x

Answer:

The price elasticity of demand is -10

Step-by-step explanation:

Given

$p_1,p_2 = 50,40$

$q_1,q_2 = 400,500$

Solving (a): The coefficient of price elasticity of demand (k)

This is calculated as:

$k = \frac{\triangle q}{\triangle p}$

So, we have:

$k = \frac{500 - 400}{40 - 50}$

$k = \frac{100}{-10}$

$k = -10$

<em>Because |k| > 0, then we can conclude that the company made a wise decision.</em>

KiRa [710]

Answer:

112 people

Step-by-step explanation:

$\frac{4}{50}$ = $\frac{x}{1400}$ write the proportion where x is the number of people with a missplaced time

50x = 5600 cross multipy

x = 112 divide both sides by 50
