It is important to Remember the negative exponent law.

X^-m = 1/X^m

1/10^2 = 10^-2.

Answer:

When we know all 3 sides we use the law of cosines

a = 47

b = 11

c = 38

cos (A) = (b^2+c^2-a^2) / (2bc)

cos (A) = -0.7703349282

Angle A = 140.38

cos (B) = (a^2 + c^2 -b^2) / (2ac)

cos (B) = 0.9888017917

Angle B = 8.5826 degrees

cos (C) = (a^2 + b^2 -c^2) / 2ab

cos (C) = 0.8568665377

cos (C) = 31.033 degrees

Angle W would be the smallest angle so it equals

31.033 degrees or rounded to nearest tenth

31.03

Given:

notsponge [240]

A line bisector is a straight line that divides a given line into two equal parts. Thus the following steps are required by Naomi to show that point D is equidistant from points A and C.

BD ⊥ AC (given)

BD = 3 units, and AC = 8 units.

BD is the perpendicular bisector of segment AC (given)

Thus,

<BDA ≅ <BDC (right angles formed by a perpendicular bisector)

AD ≅ DC (equal parts of a bisected line)

AD ≅ DC = 4 units

Thus joining points B to A, and B to C,

BA ≅ BC.

So that applying Pythagoras theorem to ΔABD, we have:

$/hyp/^{2}$ = $Adj 1^{2}$ + $Adj 2^{2}$

$AB^{2}$ = $3^{2}$ + $4^{2}$

= $\sqrt{25}$

AB = 5 units

So that,

BA ≅ BC = 5 units

Therefore, it can be concluded that point D is equidistant from points A and C.

What is 70.371 to two decimal places

elena-14-01-66 [18.8K]

Two decimal places to the left or right? If it’s to the right (postitive) then it’s 7037.1 if it’s to the left (negative) then it’s .70371, hope this helped!

Barbara claims that her horse can do simple addition problems. She showed her horse 8 different cards with simple addition probl

Nataliya [291]

Answer:

"Yes, the chances of getting 8 correct when guessing are very low"

Step-by-step explanation:

The point diagrams show us how likely is the occurrence of an event. When casting 8 coins there is a chance to get between 1 and 8 tails.

The dot plot tells us how many times 1, 2, 3, 4, 5, 6, 7 or 8 tails were obtained. When the number of trials increases, then the value with the most points in the diagram represents the number of queues most likely to be obtained, and the value with fewer points represents the least probable number of queues that can be obtained by casting 8 times a coin .

The dot plot for the experiment shows that it is very unlikely to get 8 queues when casting 8 coins. Of 53 times, this only happened once.

Just as it is unlikely to get 8 tails when throwing 8 coins, it is also unlikely that a horse guesses the 8 correct answers of the 8 simple sum problems. Then, the horse of barbara maybe did not guess the 8 answers.

Therefore the correct answer is option A:

"Yes, the chances of getting 8 correct when guessing are very low"

If sec theta = 5/3 and the terminal point determined by theta is in quandrant 4, then:

zubka84 [21]

Answer:

Step-by-step explanation:

I believe the answer is C.

Secant is just 1/cos

In that case,

sec∅ = 5/3 = cos∅ = 3/5
