Find the solution of 3 to the square root of x+6=-12 , and determine if it is an extraneous solution. (1 point)
x= -3; extraneous
x = -3; not extraneous
x= 10; extraneous
x= 10; not extraneous
Answer:
x= 10; extraneous
Step-by-step explanation:
Given the expression:
3√x+6 = -12
We are to find the value of x
Divide both sides by 3
3√x+6/3 = -12/3
√x+6 = -4
Square both sides
(√x+6)² = (-4)²
x + 6 = 16
x = 16-6
x = 10
Hence the solution is x =10 and it is extraneous solution

-81 = 5x + 3x + 3x - 1
solve the multi step equation
Answer:
x= -7.27
Step-by-step explanation:
-81 = 5x + 3x + 3x - 1
combine all like terms
-81=11x-1
add 1 on both sides
-81=11x-1
+1 +1
-80=11x
divide by 11 on both sides to get x by itself
-80/11=11x/11
x=-7.27
7. In the figure, P, Q and R points on level ground in a park. R is 600 m from Q and on a bearing of 305° from Q. Q is 950 m from P and on a bearing of 078° from P
Im having trouble with finding the distance. a
Answer:
The answer is below
Step-by-step explanation:
From the image:
∠P + ∠Q = 180° (consecutive angles are supplementary)
78 + ∠Q = 180
∠Q = 180 - 78
∠Q = 102°
∠RQN = 360° - 305° =(sum of angle in a point)
∠RQN = 55°
∠RQN + ∠RQP = 102°
∠RQP = 102 - 55 = 47°
a) Let PR = x
Using cosine rule:
[tex]x^2=600^2+950^2-2(900)(600)cos(47)\\\\x^2=485021.9\\\\x=\sqrt{485021.9} \\\\x=696 \ m[/tex]
Therefore PR = 696 m
b) Let ∠RPQ be A°
Using sine rule:
[tex]\frac{sin(A)}{600} =\frac{sin(47)}{696} \\\\sin(A)=\frac{sin(47)}{696} *600\\\\sin(A)=0.6304\\\\A=sin^{-1}(0.6304)\\\\A=39^0[/tex]
∠RPQ = 39°
Hence the bearing of R from P = ∠NPR = 78° - 39° = 39°

It takes a word processor 26 minutes to word process and spell check 6 pages. Find how long it takes her to word process and spell check 27 pages. It takes the word processor minutes
Answer:
It takes the word processor 117 minutes to word process and spell check 27 pages.
Step-by-step explanation:
With the information provided, you can use a rule of three to find how long it would take to word process and spell check 27 pages given that it takes 26 minutes to word process and spell check 6 pages:
6 pages → 26 minutes
27 pages → x
x=(27*26)/6=117 minutes
According to this, the answer is that it takes the word processor 117 minutes to word process and spell check 27 pages.

Answer:
The time he spent at his friend's house is represented by the horizontal line, from .5 to 1.5 hours, which means he stayed at his friend's house for 1 hour.
Answer:
1 hour
Step-by-step explanation:
1) so lets look at the various aspects of this graph,
the first thing we see is a downhill spike from(0,4) to (0.5,2)
we can assume this segment is from riding to his friends house from school, as thats the first thing stated in this scenario. Next we notice a horizontal line(note: horizontal line means 0 slope, AKA no distance travelled) since Joey is not travelling at this time(hence the horizontal line) we can assume that thats when he was at his friends house. to find the amount of time he was at his friends house simply subtract the endpoints of the horizontal line
so: 1.5-0.5=1
he was at his friends house for 1 hour

In ΔOPQ, o = 4.4 inches, p = 9.6 inches and ∠Q=89°. Find the length of q, to the nearest 10th of an inch.
Answer: 10.49026 = 10.5
Step-by-step explanation:
The length of the side q of the triangle OPQ is 10.5 inches.
What is cosine law?The law of Cosines, also known as Cosine Rule or Cosine Formula basically relates the length of the triangle to the cosines of one of its angles.
Given that, in a triangle OPQ, O = 4.4 inches, p = 9.6 inches and ∠Q=89°, we need to find the measurement of side q,
So, using cosine law for triangles,
q² = p²+o²-2poCos(89°)
= 4.4²+9.6²-2(4.4)(9.6)Cos(89°)
= 10.5
Hence, the length of the side q of the triangle OPQ is 10.5 inches.

in the spring temperatures rise on average 6 degrees every 5 days. at that rate how many degrees would the temperature have risen after 30 days
Answer:
Ok, this is pretty simple. So, if it rises 6 degrees every five days, then we have to figure out how many "five days" are in 30 days. It would be 6! So now all we have to do is multiply. 6 times 6 equals 36 degrees.
The answer is 36 degrees.
Step-by-step explanation:
Answer:
36
Step-by-step explanation:
If it rises 6 degrees every 5 days, we just need to figure out how many 5 days are in 30 days. When you solve, you'll get 6. Now we can just multiply 6 x 6 = 36. Hope this helped, please mark brainliest if it did
