Answer:
B) x = 2√2, y = 2
Step-by-step explanation:
The easiest way to solve this is to see that because one corner is 90 degrees, and the other 45, then the third one must also be 45. This means that the two sides on the right angle are the same length, so y = 2.
With that then, you can use the Pythagorean theorem to solve for x:
[tex]x = \sqrt{2^2 + 2^2}\\x = \sqrt{4 + 4}\\x = \sqrt{8}\\x = 2\sqrt{2}[/tex]
So the correct answer is b. x is equal to two root two, and y is equal to two.

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
Answers
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

What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
We have been given that a jar contains n nickels and d dimes worth a total of $30.
To determine the equation model that represents the given information.
As per the given information, the algebraic form is:
quantity of nickels + quantity of dimes = total worth
n + d = 30
Thus, the required equation model is n + d = 30 which represents a jar containing n nickels and d dimes worth a total of $30.
Hence, the correct answer would be option (D).

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
Answers
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

A hospital employs a total of 77 nurses and doctors. The ration if nurses to doctors is 9:2. How many nurses are employed at the hospital? How many doctors are employed at the hospital?
Answers
Answer: 63 nurses and 14 doctors
so you know the ratio is 9:2. that means for every 9 nurses there are 2 doctors. i didn't make an equation but i counted it.
if theres 9 (9*1) nurses theres 2 (2*1) doctors
if theres 18 (9*2) nurses theres 4 (2*2) doctors
if theres 27 (9*3) nurses theres 6 (2*3) doctors
you get the point so i multiplied 7 to 9 and 7 to 2, which means:
if theres 63 (9*7) nurses theres 14 (2*7) doctors

Im having trouble with finding the distance. a
Answers
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°

Answers
Step-by-step explanation:
For the quadratic equation to have 1 repeated real solution, the discriminant b² - 4ac must be zero.
=> (-z)² - 4(z - 5)(5) = 0
=> z² - 20(z - 5) = 0
=> z² - 20z + 100 = 0
=> (z - 10)² = 0
Therefore z = 10.
