omeli [17]

Answer:

25x² − 20x + 4

Explanation:

(5x − 2)²

= (5x + −2)(5x + −2)

= (5x)(5x) + (5x)(−2) + (−2)(5x) + (−2)(−2)

= 25x² − 10x − 10x + 4

= 25x² − 20x + 4

Find the following measure for this figure.

ss7ja [257]

Answer: last option (5π√146 units²)

Step-by-step explanation:

To solve the exercise you must apply the formula for calculate the lateral area of a cone, which is shown below:

$LA=r*L*\pi$

where r is the radius but L is the slant height.

As you can see in the figure attached:

$r=5$

But you need to find the slant height with the Pythagorean Theorem (L would be the hypotenuse):

$L=\sqrt{11^2+5^2}=\sqrt{146}$

Substitute into the formula, then:

$LA=(5)(\sqrt{146})\pi=5\pi\ \sqrt{146$ units²

Eric invested 5000 dollars in the stock market. The value of his stock increased by 13%. a) what is the amount earned from this

blagie [28]

Answer:

$Earnings = 650$

$New\ Value = 5650$

Step-by-step explanation:

Given

$Amount = 5000$

$Rate = 13\%$

Solving (a): The earnings.

This is calculated as:

$Earnings = Amount * Rate$

$Earnings = 5000 * 13\%$

$Earnings = 650$

Solving (b): New Value

This is calculated as:

So, we have:

$New\ Value = Amount + Earnings$

$New\ Value = 5000 + 650$

$New\ Value = 5650$
