estimate √9.7+3.88×6.21
9514 1404 393
Answer:
a little more than 27
Step-by-step explanation:
Estimates are generally made by approximating the numbers using 1 or 2 significant digits. The idea is to do as much mental arithmetic as possible, not involving a calculator. Here, the estimate can be based on rounding the values like this:
√9.7 +3.88 × 6.21 ≈ √9 +4 × 6 = 3 +24 = 27 . . . estimated expression value
__
Another aspect of estimating is determining the approximate error involved.
We know that √9.7 will be more than √9 = 3, and less than √10 ≈ 3.16*. Its real value may be about 3.1.
3.88 is less than 4 by 0.12, or 3%. 6.21 is greater than 6 by .21, or 3.5%. So, the estimated product of 24 will be on the order of -3% +3.5% = 0.5% too low. Of course 1% of 24 is 0.24, so 1/2% will be about 0.12. Now, we are able to estimate that our estimate is about 0.2 units too low. (The actual value of the expression is an irrational number that rounds to about 27.2093.)
_____
* The value of 3.16 for √10 is not so hard to remember, because it is just slightly more than π ≈ 3.14.
__
Additional comment
Small percentages can usually be added and subtracted without introducing too much additional error. (The smaller the percentages, the less additional error is introduced.) Here, the error in our estimated product can be more accurately determined by computing ...
(1 -3%)(1 +3.5%) = 1 +0.5% -0.105% = 1 +0.395% . . . . . . (not 1 +0.5%)
That is, our product's actual value is 24.0948, not 24.12.

What is the distance (length) of side LM?
Answer:
Distance, d = √((x2 - x1)² + (y2 - y1)²)
L(x1, y1) => L(-3, -1)
M(x2, y2) => M(2, 3)
Distance LM = √((2 - -3)² + (3 - -1)²)
= √((2 + 3)² + (3 + 1)²)
= √((5)² + (4)²)
= √(25 + 16)
= √ 41
= 6.4 unit
1/sin30 - √3/cos10 =4 prove it?
Step-by-step explanation:
1/sin10-√3/cos10
= (cos10 - √3sin10)/cos10sin10
multiplying 1/2 in denominator and numerator
= {(cos10/2) - (√3sin10/2)}/(cos10sin10/2)
= (cos60cos10 - sin60sin10)/(cos10sin10/2)
= cos(60 + 10)/(cos10sin10/2)
= cos70/(cos10sin10/2)
= 2cos70/cos10sin10
multiplying 2 on numerator and denominator
= 4cos70/2sin10cos10
=4cos70/sin20
=4cos70/cos70
= 4 proved

So y=mx+b is still prevalent here even if it's an inequality. Meaning your slope AND y-intercept can help you. Even if it's in ax+by=c you can easily get the y alone into slope-intercept.
y<_3x+5 for example. For one, it is y is less than or equal to 3x+5. So the line shouldn't be dotted. So that leaves us with the two far-right graphs to look at. 5 is our y-intercept in the equation. So look at our graph and see which one has the line passing through 5. They both do. Okay, well we can still use our sign, it shows that y is LESS than 3x+5. So the shaded blue part should be on the right. If it was the other way around it would be the left. So our graph should be the far right for this equation.
Hope this helps... I know it's kind of messy. If you need any more help let me know. But I hope I outlined what to look for.

11 b i. 8 × 10⁻⁷
11 b ii. 0.0000008
Step-by-step explanation: 8: the image is a bit out of focus, so it's hard to tell what all the exponents are. Just remember that for negative exponents, the larger the number, the smaller the value.
9. Following the examples given, the exponent tells how many places to count from right to left to move the decimal from standard form to wavelength and vice-versa.
9b. Just put the numbers from standard form in order and find the corresponding color.
10. For multiplication, multiply the numbers to the left of the × and add the exponents of the 10. For division, Divide the numbers on the left and subtract the exponents of 10.
11a add the powers. Just like the first part of #10
11b same procedure as #10 (The more you practice, the more likely you will remember)

If Z is the centroid of triangle TUV, TZ=60, XZ=28, and WZ=25, find each missing measure
The measure of length ZV, ZY, ZU, TY, and XV are 56, 30, 50, 60, and 78.
If Z is the centroid of triangle TUV, then the following are true:
ZV = 2ZX
Given that ZX = 28,
ZV = 2(28)
ZV = 56
Similarly, TZ = 2ZY
60 = 2ZY
ZY = 60/2
ZY = 30
Also, ZU = 2WZ
ZU = 2(25)
ZU = 50
TY = 2ZY
TY = 2(30)
TY = 60
XV = XZ + ZY
XV = 28 + 50
XV = 78
Therefore the measure of length ZV, ZY, ZU, TY, and XV are 56, 30, 50, 60, and 78.

What is the slope of a line which makes an angle of 45 degree with x-axis? *
Answer:
First we have to find slope m=Tan45°=1
so slope is 1.
Answer:
slope = 1
Step-by-step explanation:
The relationship between slope and the positive angle it makes with the x- axis is
slope = tanθ ( θ is the angle measured from the x- axis ), then
slope = tan45° = 1

Given that f ( x ) = 3 x − 2 and g ( x ) = 2 x , evaluate f ( g ( − 1 ) )
g(x) = 2x
9(-1) = -2
f(x) = 3x-2
f(g(-1)) = f(-2) = 3*(-2) - 2 = -8
Answer:
-8
Step-by-step explanation:
g(-1)= 2 * -1 = -2
So f(g(-1)) will be f(-2)
F(-2) = (3 * -2) - 2
= -6 - 2
= -8
