<h3>Answer: -1</h3>

Step-by-step explanation: When evaluating expressions with parentheses, we must remember PEMDAS (Order of operations): Parentheses, exponents, multiplication/division, and addition/subtraction.

So, we first need to solve everything inside the parentheses:

3 + 2 = 5

Now, we can solve the rest of the expression:

4 - 5 = -1

The answer is -1. You have to solve inside the parentheses, then distribute the negative. Then subtract -5 + 4. = -1

Genotypes usually involve some combination of dominant and recessive alleles. What is the most common inheritance pattern?

viva [34]

Genotype is the genetic composition of an organism. Alleles are the alternative forms of a gene, they can either be dominant alleles (masks the other allele) or recessive alleles (masked by the dominant allele when present). Autosomal dominant and the autosomal recessive are the most common inheritance patterns.

2-sin^2x=2cos^2(x/2)

nadezda [96]

$2-\sin^2x=2\cos^2\dfrac x2$
$1+\cos^2x=1+\cos x$
$\cos^2x-\cos x=0$
$\cos x(\cos x-1)=0$

and this has solutions of $x=\dfrac{n\pi}2=\dfrac{(2k+1)\pi}2$ and $x=n\pi=2k\pi$ where $k\in\mathbb Z$ .

The cost of producing hard drives has three parts: cost of materials, cost of labor, and cost of equipment. To produce x hard dr

LenKa [72]

Let $x$ represent the number of hard drives produced.
The first thing we need to do is convert 10 cents to dollars:
$10cents( \frac{1dollar}{100cents} )=0.1dollar$ . Now, we know that the the cost of materials is 30 dollars and the cost of labor is 0.1 dollars, so the total coast to produce $x$ hard drives will be: $30+0.1=30.1x$ .
Now the only thing left is add t<span>he cost of equipment to complete our function:
</span> $f(x)=30.1x+10000$

We can conclude that the equation that could represent the cost function for making x hard drives is <span>f(x)=30.1x+10,000</span>
