Solution:
Given, equation is
We have to find the roots of the given quadratic equation
Now, let us use the quadratic formula
--- (1)
Let us determine the nature of roots:
Here in a = 1 ; b = -2 ; c = 5

Since , the roots obtained will be complex conjugates.
Now plug in values in eqn 1, we get,

On solving we get,



we know that square root of -1 is "i" which is a complex number

Hence, the roots of the given quadratic equation are 1 + 2i and 1 – 2i

What percent of $15 is $9?


PLEASE HELPPP :((

Answers

60% should be the right answer luv

60 percent of $15 is $9.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Let x be the unknown percent.

Here, x% of 15 =9

⇒ x/100 ×15=9

⇒ 15x=900

⇒ x=900/15

⇒ x=60%

Therefore, 60 percent of $15 is $9.

_______cm2

Answers

Answer:

The surface area of each ice cream of the three ice cream  is approximately 706.86 cm²

Step-by-step explanation:

The given parameters are;

The diameter of the cones = 10 cm

The radius of the cone, r = 5 cm

The assumption of the shape of the capping of the ice cream = Hemisphere

The surface area of an hemisphere = 3·π·r²

The surface area of each ice cream = 3 × π × (5 cm)² ≈ 235.62 cm²

The surface area of each ice cream of the three ice cream  = 3 × 235.62 ≈ 706.86 cm²

The surface area of each ice cream of the three ice cream  ≈ 706.86 cm².

The regular price of a baseball hat is 14.45$. If Carlos buys the baseball hat on sale for 20% off the regular price, how much change will he receive after paying with 20$

Answers

Answer:

$8.44

Step-by-step explanation:

To find the 20%

x/14.45=20/100

14.45×20=289

289÷100=2.89

We then subtract 2.89 from 14.45 to get the selling price.

14.45-2.89=11.56

$11.56 is the price of the baseball hat on sale.

To get the change

20-11.56=8.44

$8.44 is the change

What is the initial value of the equation shown?

y = −2x − 5

−5
−2

5

Answers

Answer:

-5

Step-by-step explanation:

The initial value is also known as the y-intercept (in other words, the output value when the input of a linear function is zero). In the equation;

y = mx + b

The variable b represents the y-intercept because the x-value is equal to zero. By applying this to our equation, we get:

y = mx + b

y = -2x - 5

And thus, (-5) is our answer. Good luck and keep studying!

Answer:

6!

Step-by-step explanation:

I'm not as sure about this answer, but I got it like this!

We know that a triangle adds up to 180. Two of our given measurements are 90 and 63. Adding those together we get 153. To solve for x, you'd have to subtract that from 180.

From there, you get 27! That's the answer to the equation, but not the value of x.

4 time 6 ( which is x) is 24, plus 3 is 27, so we know that x is 6!

Answer:

Step-by-step explanation:

Putting values of x in equation

Y = 4(-3) - 4

= - 12 - 4 = - 16

Y = 4(-2) - 4

= - 8 - 4 = - 12

Y = 4(-1) - 4

= - 4 - 4 = - 8

Y = 4(0) - 4

= 0 - 4 = - 4

Y = 4(1) - 4

= 4 - 4 = 0

Y = 4(2) - 4

= 8 - 4 = 4

Y = 4(3) - 4

Step-by-step explanation:

A daycare employee earns $\$10.90$ per hour for the first $40$ hours he works in $1$ week. He is paid $1.5$ times that rate for each additional hour that he works. How much money does he earn working for $43$ hours in $1$ week?

Answers

Given:

Employee earns $10.90 per hour for the first 40 hours he works in 1 week.

He is paid 1.5 times that rate for each additional hour that he works.

To find:

How much money does he earn working for 43 hours in 1 week?

Solution:

Earning for first 40 hours = $10.90 per hour

Earning for additional hours after 40 hours = 1.5 × $10.90 per hour

                                                                        = $16.35 per hour

In 43 hours, 3 hours are additional after first 40 hours.

Earning for first 40 hours = 40 ×  $10.90

Earning for additional 3 hours = 3 ×  $16.35

Now,

[tex]\text{Total earnings}=40\times 10.90+3\times 16.35[/tex]

[tex]\text{Total earnings}=436+49.05[/tex]

[tex]\text{Total earnings}=485.05[/tex]

Therefore, the total earnings for 43 hours in a week is $485.05.
