Solve for x. Leave your answer in simplest radical form.
SOMEONE HELP ME PLEASE I NEED IT, it needs to be in radical form
Step-by-step explanation:
step 1. let's call the line in the middle y.
step 2. y = sqrt(5^2 + 7^2) = sqrt(74). pythagorean theorem.
step 3. x^2 + y^2 =100 (pythagorean theorem))
step 4. x^2 + (sqrt(74))^2 = 100.
step 5. x^2 = 100 - 74
step 6. x^2 = 26
step 7. x = sqrt(26). note: sqrt is the square root.
The value of the x is [tex]\sqrt{26}[/tex].
To understand more, check below explanation.
Pythagoras theorem :Apply Pythagoras theorem in right side triangle,
Hypotenuse[tex]=\sqrt{5^{2}+7^{2} } =\sqrt{25+49}=\sqrt{74}[/tex]
Now apply Pythagoras theorem in the left side triangle,
[tex]Hypotenus^{2} +x^{2} =10^{2} \\\\(\sqrt{74} )^{2} +x^{2} =100\\\\x^{2} =100-74=26\\\\x=\sqrt{26}[/tex]
Hence, the value of the x is [tex]\sqrt{26}[/tex].

Does this diverge or converge?
Answer:
L = 7/6 , and the correct option is B, the series diverges.
Step-by-step explanation:
Here we have that:
[tex]an = \frac{(3n + 3)*7^n}{6^{n+4}}[/tex]
Now we want to see the quotient test, then we need to do find the value of the quotient as n tends to infinity. Then we first need to find the quotient:
[tex]a(n + 1)/a(n) = \frac{(3(n + 1) + 3)*7^{n + 1}}{6^{n + 1 + 4}}*\frac{6^{n + 4}}{(3*(n) + 3)*7^{n}}[/tex]
We can simplify the right part to get:
[tex]\frac{(3(n + 1) + 3)*7^{n + 1}}{6^{n + 1 + 4}}*\frac{6^{n + 4}}{(3*(n) + 3)*7^{n}}= \frac{(3n + 3 + 3)*7^{n + 1}}{6^{n + 5}}*\frac{6^{n + 4}}{(3*n + 3)*7^{n}}[/tex]
[tex]\frac{(3n + 3 + 3)*7^{n + 1}}{6^{n + 5}}*\frac{6^{n + 4}}{(3*n + 3)*7^{n}}= \frac{(3n + 3 + 3)*7}{(3*n + 3)*6}[/tex]
Now we want to find the limit of this as n goes to infinity, we can see that both parts will tend to infinity, then we need to use the Lhopital rule and find the limit of the quotient of the first derivatives.
The first derivatives are:
For the denominator: (3*6)
For the numerator: (3*7)
Then we need to find the limit as n goes to infinity to:
[tex]\frac{3*7}{3*6} = \frac{7}{6}[/tex]
But this does not depend on the value of n, then the limit is just 6/7.
L = 7/6
And 7/6 > 1.
Then we can conclude that our series diverges.

En un día de febrero, una ciudad de Estados Unidos registró una temperatura mínima de 9° bajo cero y una temperatura máxima de 13°C. ¿De cuántos grados fue el intervalo de temperaturas registradas?
Answer:
La cantidad de grados del intervalo de temperaturas registradas en el día de febrero mencionado es de:
5Step-by-step explanation:
En estadística, cuando se utilizan intervalos como valores para identificar datos cuantitativos, como en este caso temperaturas registradas, deben tomarse todos los valores, en este caso enteros, desde el límite inferior (temperatura mínima) hasta el límite superior (temperatura máxima), por lo cual no se puede restar el valor máximo al valor mínimo, sino que debes identificar todos los valores y después contarlos. En el caso del ejercicio dado, los grados en el intervalo mencionado son:
9°C10°C11°C12°C13°CComo puedes ver, los grados en el intervalo de temperaturas registradas serían 5.
If r=3q + 2 and q = 1/3n for n = 1,2 or 3,
what is the least possiable value of r ?
A. 1
B. 2 1/9
C. 2 1/3
D. 3
Answer:
D. 3
Step-by-step explanation:
For n = 1:
q = 1/3 * 1 = 1/3
r = 3 * 1/3 + 2 = 1 + 2 = 3
For n = 2:
q = 1/3 * 2 = 2/3
r = 3 * 2/3 + 2 = 2 + 2 = 4
For n = 3:
q = 1/3 * 3 = 1
r = 3 * 1 + 2 = 3 + 2 = 5
Therefore, from the values of r that we found (3, 4, 5), the minimal value is 3.

Find the zeros
Answer:
The zeroes of this polynomial are [tex]x_{1} \approx 0.847[/tex] and [tex]x_{2} \approx -1.180[/tex].
Step-by-step explanation:
Let [tex]3\cdot x^{2}+x - 3 = 0[/tex], the quickest and most efficient approach to find the zeroes of this second order polynomial is by Quadratic Formula. For all [tex]a\cdot x^{2}+b\cdot x + c = 0[/tex], roots are determined by:
[tex]x_{1,2} = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex] (1)
Where [tex]a[/tex], [tex]b[/tex], [tex]c[/tex] are coefficients of the polynomial.
If we know that [tex]a = 3[/tex], [tex]b = 1[/tex] and [tex]c = -3[/tex], then roots of the polynomial are, respectively:
[tex]x_{1,2} = \frac{-1\pm\sqrt{1^{2}-4\cdot (3)\cdot (-3)}}{2\cdot (3)}[/tex]
[tex]x_{1,2} =\frac{-1\pm \sqrt{37}}{6}[/tex]
The zeroes of this polynomial are [tex]x_{1} \approx 0.847[/tex] and [tex]x_{2} \approx -1.180[/tex].

Triangle QRS is isosceles with m(∠R) = 107°. What is m(∠Q)
Answer:
36.5 degrees
Step-by-step explanation:
An isosceles triangle is a triangle in which two angles are equal
The sum of angles in the triangle is 180°
If one of the angles is 107°, the sum of the other two angles is (180° - 107°) 73°
The size of each of the two angles is 73/2 = 36.5°
