8 0

Answer:

0

Step-by-step explanation:

cos(60) = ½

sin(30) = ½

cosec(30) = 2

sin(0) = 0

2 - 2 - 0 = 0

240,000 written as a whole number multiplied by a power of ten
IrinaK [193]
240,000 written as a whole number multiplied by a power of ten:

In the provided number 240,000 if we want to multiply this number by a power of ten then it would be like 240,000 raised to the power of 10  
<span><span>1.       </span>In which clearly stating that 240,000 shall multiply itself by 10 times in 240,000.
</span> <span><span>2.       </span>Hence 240, 000^10 in numerical form</span> <span><span>
3.       </span>The result is 6.340338097x10^53</span> <span><span>
4.       </span>It seems like the product is a lot bigger and capsized itself to a smaller scientific reading but its still big in value because of the its current 53 power.</span>

Hope this helps!

The length of a rectangular flower bed is 2ft longer than the width. If the area is 6ft, then what are the exact length and widt
Marizza181 [45]

Answer:

Exact dimensions:

width=-1+\sqrt{7}

length=-1+\sqrt{7}+2

length=1+\sqrt{7}

Approximate dimensions:

width=1.64575ft

length=1.64575+2

length=3.64575ft

Step-by-step explanation:

Let's assume width of rectangle is w ft

The length of a rectangular flower bed is 2ft longer than the width

so,

length =w+2

L=w+2

now, we can find area

A=L\times W

now, we can plug it

A=(w+2)\times w

A=w^2+2w

we are given area =6

so, we can set it equal

and then we can solve for w

w^2+2w=6

w^2+2w-6=0

we can use quadratic formula

ax^2+bx+c=0

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

now, we can compare and find a,b and c

a=1 , b=2 , c=-6

w=\frac{-2\pm \sqrt{2^2-4\cdot \:1\left(-6\right)}}{2\cdot \:1}

w=-1+\sqrt{7},\:w=-1-\sqrt{7}

we know that dimension can never be negative

so, we will only consider positive value

Exact dimensions:

width=-1+\sqrt{7}

length=-1+\sqrt{7}+2

length=1+\sqrt{7}

Approximate dimensions:

width=1.64575ft

length=1.64575+2

length=3.64575ft

A pair of numbers is a solution of y = -3x if the second number, y, is -3 times the first number, x.

What about the pair (-1, 4)?  If you replace x with -1, you get y = -3(-1) = 3, not 4.  So (-1, 4) is NOT a solution.

For each answer choice, you have to check all three of the given pairs.

(0, 0) is a solution because if x = 0, then y = -3(0) = 0.
(3, -9) is a solution because if x = 3, then y = 3(-3) = -9.

Can you finish it?
