Question 5(Multiple Choice Worth 4 points)

Mathematics
1 answer:
Aleks [24]3 years ago

Hello!

The number 49 is similar to other numbers like 25, 81, 4, or 64. All these numbers are perfect squares. Perfect squares are numbers multiplied by itself. Here is a list of commonly used perfect squares.

  • 1 × 1 = 1
  • 2 × 2 = 4
  • 3 × 3 = 9
  • 4 × 4 = 16
  • 5 × 5 = 25
  • 6 × 6 = 36
  • 7 × 7 = 49
  • 8 × 8 = 64
  • 9 × 9 = 81
  • 10 × 10 = 100
  • 11 × 11 = 121
  • 12 × 12 = 144

From the list above, the square root of 49 is 7, but the question asks for the <u>negative</u><u> square root of 49</u>, which is written as: -√49.

To simplify this expression, first, simplify the radical, and then multiply the product by negative one.

7 × -1 = -7

Therefore, the negative square root of 49 is choice C, - 7.

7. A person has $10,100 to invest in two different stock. Stock ABC costs $32 per share and pays dividends of $1.20 per share. S
Vesna [10]

Answer:

invested in ABC = $3200

Step-by-step explanation:

given data

total invest = $10,100

Stock ABC costs = $32 per share

dividends = $1.20 per share

Stock XYZ costs = $23 per share

dividends = $1.40 per share

earn a total dividends = $540

solution

we can say total money invest express as

total money invested = 32 × P + 23 × Q

here person buys stocks of ABC is P and buys stocks of stocks of XYZ is Q

$10,100 = 32 × P + 23 × Q  

we can also write this as by multiply 3 both side

$30,300 = 96 × P + 69 × Q  ......................1

and total dividends will be

total dividends =  1.2 × P +1.4 × Q

$540 =  1.2 × P +1.4 × Q

we can also write this as by multiply 80 both side

$43200 = 96 × P + 112 × Q  ....................2

so from equation 1 and 2 , subtracting 1 from 2

we get

Q = 300

and P = 100

so that we invest 100 × 32

invested in ABC = $3200
