Find the area of the triangle below.
Carry your intermediate computations to at least four decimal places. Round your answer to the nearest hundredth

Answers

Answer:

20

Step-by-step explanation:

Since this is not a right angle, we can use the formula [tex]Area= Sin(y) (\frac{1}{2}ab)[/tex]

a=7

b=10

y=35

So, when we plug these values in, we get:

[tex]a=Sin(35)(\frac{(10)(7)}{2})\\\\=35sin(35)\\=20.075\\[/tex]

rounded to the nearest hundredth, I believe it's 20.

Nancy bought a soft drink for 2 dollars and 9 candy bars. She spent a total of 38 dollars. How much did each
candy bar cost?

Answers

Answer:

$4

Step-by-step explanation:

Because we know that Nancy bought a drink for 2 dollars, and we are just trying to find the cost of the candy bars, we can subtract 2 dollars from the drink from the total cost:

38 - 2 = 36

Now, the 9 candy bars cost 36 dollars, so to find the individual price of each candy bar, we divide 36 by 9:

36 / 9 = 4

So, each candy bar costs 4 dollars

Hope this helps :)

Answer:

4 dollars

Step-by-step explanation:

38 - 2

= 36

36÷9 ( candy bars)

= 4 dollars

Equation: M+6/-3=4
What did you do?
Simplify/complete sentence

Answers

M + 6/-3 = 4
Following the order of operations, 6 divided by -3 is -2. So we can replace that with -2 and get:

M+-2=4

Adding a negative is the same thing as subtracting.
M-2=4

Then we can add 2 to both sides to get rid of the 2.
M-2+2=4+2
M = 6

What is the rotation of point A (-2, 3). 90 degrees?
A. (2,3)
B. (-2,-3)
C. (3,-2)
D. (3,-2)

Answers

Step-by-step explanation:

Let's pretend our point is actually a complex number. That would make the point -2–3i. Why would we do this? Well, rotation of complex numbers is simply a matter of multiplication, in this case by 1∠−90° , or -i.

So to start, you shift the point of rotation to 0+0i, rotate it by multiplying, then shift it back to the axis of rotation.

z=−i[(−2−x0)+(−3−y0)i]+(x0+iy0)

=−3−y0+x0+(2+x0+y0)i

x=Rz

y=Iz

Thus the new point is at (−3+x0−y0,2+x0+y0)

hence (-3,2)

What is the 40th term of the arithmetic sequence?

21, 18, 15, 12, 9,...


−96


6


138


−99

Answers

Answer:

We start off with 21 as the first term. So a1 = 21

The common difference is d = -3 because we subtract 3 each time to get from one term to the other (eg: 21 to 18 is minus 3)

The nth term of an arithmetic sequence is found by using this formula

an = a1 + d(n-1)

let's plug in the values we have so far to get

an = 21 + (-3)(n-1)

an = 21 - 3(n-1)

an = 21-3n+3

an = -3n+24

Why do this? Well it's helpful so we can find any term in the formula we want. In this case, we want the 40th term. So just plug in n = 40 from here and you're done

an = -3n+24

a40 = -3*40+24

a40 = -96

pointing you to the answer of choice B) -96

In fact, in 2010 the European Commission released an analysis of 50 studies conducted on GE foods over the last 25 years and concluded that GE technologies posed no greater risks than conventional breeding technologies....The reason I dont worry about GMOs [genetically modified foods] is not because someone has convinced me with a big study that theyre safe, says Michael Eisen, an associate professor of genetics, genomics, and development at the University of California, Berkeley, and an investigator at the Howard Hughes Medical Institute. Its because when I look at the technology, I understand what this technology is doing. Theyre introducing proteins that have been very well characterized into plants, and I dont see any reason at all to suspect that these are harmful. . . .Some scientists, however, believe questions about the safety of GE foods are far from answered. Doug Gurian-Sherman, senior scientist with the Food and Environment Program at the Union of Concerned Scientists, says the question is not whether theres risk involved in GE foods, but whether its greater than risks posed by conventional foods. Because of the greater capacity to bring unknown quantities into the food supply, Im of the school that says it has somewhat higher potential for risk, he says. Other scientists say no. But I dont think its a settled debate.Hansen responds to claims that theres no evidence of harm from GE foods by saying, Thats just not true. I can show you all kinds of studies in the scientific literature that have . . . raised red flags that need to be followed up on. In one such study, investigators reviewed 19 studies of mammals fed GE soybeans and maize. They found that several convergent data appear to indicate liver and kidney problems as end points of GMO diet effects, with the kidneys more affected in males and the liver more affected in females. The authors, noting the limitations of the 28- and 90-day assays they reviewed, pointed out that chronic toxicity testing is not required for GE foods, but that it should be.3Select the correct answer.Which description provides the best objective summary of the article in the passage?A.
