Solve For X. Enter The Solutions From Least To Greatest. (x+15)^2-10=0

Answers

Answer 1

Answer:

lesser x = -1.84lesser x = -8.16

Step-by-step explanation:

Given the expression

[tex]\left(x+5\right)^2-10=0[/tex]

Add 10 to both sides

[tex]\left(x+5\right)^2-10+10=0+10[/tex]

Simplify

[tex]\left(x+5\right)^2=10[/tex]

[tex]\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]

solve

[tex]x+5=\sqrt{10}[/tex]

Subtract 5 from both sides

[tex]x+5-5=\sqrt{10}-5[/tex]

[tex]x=\sqrt{10}-5[/tex]

[tex]x=-1.8[/tex]

so

[tex]x+5=-\sqrt{10}[/tex]

Subtract 5 from both sides

[tex]x+5-5=-\sqrt{10}-5[/tex]

Simplify

[tex]x=-\sqrt{10}-5[/tex]

[tex]\:x=-8.2[/tex]

As -1.84 > -8.16

so

lesser x = -1.84lesser x = -8.16

What is the definition of the ratio?In mathematics, a ratio is a term used to compare two numbers. It is used to express how large or small an amount is in comparison to another. A ratio compares two quantities by dividing them. The dividend is referred to as the 'antecedent,' while the divisor is referred to as the 'consequent.'

For the given question.

Let the number of girls be 'x' = 63.

Let the number of boys be 'y'.

The ratio of girls to boy is 9:7.

Thus,

x/y = 9/7

Boys  = ?

y = 7x/9

Put x = 63

y = 7×63/9

y = 49

Thus, the number of boys attended are 49.

Okay so I have no clue what to do on these problems lol. Can someone help explain it please? Thank you

Answers

Answer:

you use the Pythagorean theorem (a^2 +b^2 = c^2)

a^2 +17^2 = 19^2

a^2 + 289 = 361

a^2 = 72

a = (square root)72

5^2 + 13^2 = c^2

25 + 169 = c^2

194 = c^2

c= (square root)194

a^2 + 10^2 = 20^2

a^2 + 100 = 400

a^2 = 300

a = (square root) 300

5^2 + 14^2 = c^2

25 + 196 = c^2

221 = c^2

c= (square root) 221

use the quotient rule to find the derrivatives of 3/x^2​

Answers

Answer:

f'(x) = -6/x³

Step-by-step explanation:

We are given;

f(x) = 3/x²

Using quotient rule, we can write as;

f(x) = g(x)/h(x)

To find the derivative, from quotient rule, we can write;

f'(x) = [(h(x)*g'(x)) - (g(x)*h'(x))]/(h(x))²

g'(x) = 0

h'(x) = 2x

Thus;

f'(x) = [(x²*0) - (3*2x)]/(x²)²

f'(x) = -6x/x⁴ = -6/x³

f'(x) = -6/x³
