Answer:

Diana receives $84 in interest after 2 years.

Step-by-step explanation:

I = PRT

Interest = Price times Rate times Time

Price = $140

Rate = 3% (as a decimal it's 0.3)

Time = 2

I = 140(0.3)(2)

I = 42(2)

I = 84

Diana receives $84 in interest after 2 years.

I hope this helps =)

Can someone help me asap !!
aivan3 [116]

Answer:

The answer is negative. Answer choice B

Step-by-step explanation:

Here is the question:

-3^40(5.6/2.1)

According to order of operations, we must do -3^40 first.

Its important to note that -3^40 is different than (-3)^40. In the problem you specified, the ^40 only applies to the 3, not -3. So, first we do 3^40 which is a huge number. And then, we need to add a negative symbol to that huge number. So now we have a massive negative number multiplied by 5.6/2.1, which is obviously positive. Obviously, a negative number multiplied by a positive number is still negative. Therfore, the answer is negative.

I hope my answer helped you :)

Right triangle means:
sin, cos, and tangent

Here, we can see that:
sin 35° = \frac{x}{20}

Simplify.

20sin 35° = x

Multiply 20 by sin of 35 degrees.

x = 11.47(ROUNDED)

HELP! A semi circle of radius 6 is centered at the origin as shown. A rectangle has two of its vertices at (5,0) and (-5,0) and
Ugo [173]

The Area of rectangle is "30 \ unit^2" and the equation of the semi circle is "y = \sqrt{36-x^2}".

According to the question,

The vertices of rectangle,

(5, 0) and (-5, 0)

Length,

l = 10 unit

Breadth,

b = 3 unit

Radius of semi circle,

r = 6

Centre of origin,

(0, 0)

As we know,

→ The Area of rectangle is:

= Length\times Breadth

= 10\times 3

= 30 \ unit^2

and,

→ The Equation of semi circle is,

y = \sqrt{r^2-x^2}

by substituting the values, we get

  =\sqrt{(6)^2-x^2}

  = \sqrt{36-x^2}

Thus the above is the correct answers.
