The product of all the values of a, such that f(a)=f(2a) is -1/2

Given the function below;

f(x)=1/x + x

f(a) = 1/a + a

f(2a) = 1/2a  + 2a

If f(a) = f(2a), hence;

1/a + a = 1/2a + 2a

Collect the like terms

1/a - 1/2a = 2a - a

2-1/2a = a

1/2a = a

Cross multiply

2a² = 1

a² = 1/2

a = ±√1/2

The values of a are √1/2 and -√1/2

Product = -√1/2 * √1/2

Product = -1/2

Hence the product of all the values of a, such that f(a)=f(2a) is -1/2

The value of x in the triangle is (d) 7

The complete question is in the attached image.

From the attached image of the triangle, we can see that the triangle is a right triangle, and x can be solved using the following sine function

[tex]\sin(45) = \frac{x}{7\sqrt 2}[/tex]

Evaluate sin(45)

[tex]\frac 1{\sqrt 2} = \frac{x}{7\sqrt 2}[/tex]

Solve for x

[tex]x = \frac{7\sqrt 2}{\sqrt 2}[/tex]

Divide

x = 7

Hence, the value of x in the triangle is (d) 7

Answer:

y^-1 = 3x - 6

Step-by-step explanation:

f(x) = 1/3x + 2

The inverse function is where we swap out y for x and x for y. f(x) represents y, so we will be replacing it with x. Then, we solve and get a new equation for the inverse of y.

x = 1/3y + 2 (subtract 2 from both sides)

x - 2 = 1/3y (multiply by 3 on both sides)

y^-1 = 3x - 6

Answer:

x = 12.0 cm

Step-by-step explanation:

If we draw a line parallel to the 12 cm line right below the line x, a right-angled triangle is formed, with x as the hypotenuse and the shortest side equal to (8 - 7 = ) 1 cm.

∴ x² = 12² + 1²

⇒ x = [tex]\sqrt{12^2 + 1^2}[/tex]

The probability that the mean clock life would differ from the population mean by greater than 12.5 years is 98.30%.

Given mean of 14 years, variance of 25 and sample size is 50.

We have to calculate the probability that the mean clock life would differ from the population mean by greater than 1.5 years.

μ=14,

σ=[tex]\sqrt{25}[/tex]=5

n=50

s orσ =5/[tex]\sqrt{50}[/tex]=0.7071.

This is 1 subtracted by the  p value of z when X=12.5.

So,

z=X-μ/σ

=12.5-14/0.7071

=-2.12

P value=0.0170

1-0.0170=0.9830

=98.30%

Hence the probability that the mean clock life would differ from the population mean by greater than 1.5 years is 98.30%.

Answer:

x=1

Step-by-step explanation:

A geometric sequence goes from one term to the next by always multiplying or dividing by the constant value except 0. The constant number multiplied (or divided) at each stage of a geometric sequence is called the common ratio (r).

A geometric series is the sum of an infinite number of terms of a geometric sequence.

A geometric series is convergers if |r| < 1.

A geometric series is diveres if |r| > 1.

Calculate the common ratio:

[tex]r=\dfrac{18}{27}=\dfrac{18:9}{27:9}=\dfrac{2}{3}\\\\r=\dfrac{12}{18}=\dfrac{12:6}{18:6}=\dfrac{2}{3}\\\\r=\dfrac{8}{12}=\dfrac{8:24}{12:4}=\dfrac{2}{3}[/tex]

[tex]\left|\dfrac{2}{3}\right| < 1[/tex]

Therefore exist the sum.

Formula of a sum of a geometric series:

[tex]S=\dfrac{a_1}{1-r},\qquad|r| < 1[/tex]

Substitute:

[tex]a_1=27,\ r=\dfrac{2}{3}[/tex]

[tex]S=\dfrac{27}{1-\frac{2}{3}}=\dfrac{27}{\frac{1}{3}}=27\cdot\dfrac{3}{1}=81[/tex]

Answer:The answers are 0.084 or -1.184

Step-by-step explanation:

The solution is in the attached file

a) Solve the first equation for [tex]x[/tex].

[tex]x + 3y = 7 \impiles x = 7 - 3y[/tex]

Substitute this into the second equation and solve for [tex]y[/tex].

[tex]2x + 4y = 12 \implies 2(7 - 3y) + 4y = 12 \\\\ \implies 14 - 6y + 4y = 12 \\\\ \implies -2y = -2 \\\\ \implies \boxed{y=1}[/tex]

Solve for [tex]x[/tex].

[tex]x = 7 - 3y \implies x = 7-3\times1 \\\\ \implies \boxed{x = 4}[/tex]

b) Eliminate [tex]y[/tex] by combining the two equations in appropriate parts, namely

[tex]2 (2x - y) + (3x + 2y) = 2\times3 + (-3)[/tex]

and solve for [tex]x[/tex].

[tex]2 (2x - y) + (3x + 2y) = 2\times3 + (-3) \implies 4x - 2y + 3x + 2y = 6 - 3 \\\\ \implies 7x = 3 \\\\ \implies \boxed{x = \dfrac37}[/tex]

Solve for [tex]y[/tex].

[tex]2x - y = 3 \implies 2\times\dfrac37 - y = 3 \\\\ \implies \dfrac67 - y = 3 \\\\ \implies -y = \dfrac{15}7 \\\\ \implies \boxed{y = -\dfrac{15}7}[/tex]

If any numbers or constant power is zero then it will be 1

Answer:

3

Step-by-step explanation:

So anything to the power of zero is equal to 1. So you have the equation: [tex]3y^0=3(1)=3[/tex]

If this doesn't make much sense, I sometimes like to use identities to show why this is. So since you're most likely learning exponents, you likely know the identity: [tex]\frac{x^a}{x^b}=x^{a-b}[/tex] well you can use this identity to express the equation: [tex]\frac{x^a}{x^a}=x^{a-a}=x^0[/tex]. and since x^a should equal x^a, and it's being divided by it self, this is equal to 1.

Btw if you didn't understand the identity: [tex]\frac{x^a}{x^b}=x^{a-b}[/tex] I'll try to briefly explain it. The reason this is true, is because you can cancel stuff out if it's being multiplied in the denominator and numerator. For example: [tex]\frac{3a}{3}[/tex]. I can cancel out the 3, because if I multiply 3 by a, and then divide by 3, I'm going to be left with a, because they're inverse to each other. This should hold true for exponents. So you can think of the identity more like: [tex]\frac{x*x*x...\text{a amount of times}}{x*x*x\text{b amount of times}}[/tex] seeing it like this might help understand why you subtract, since you're just cancelling out the x's.

I'll give you a more definitive example to help you grasp it in an example so: [tex]\frac{2^4}{2^2}=\frac{2*2*2*2}{2*2}=\frac{2*2}{1}=2^2[/tex]. See how I canceled out 2 of the 2's, well all I was really doing was subtracting 2 from the degree of the numerator, or in other words I was subtracting the degree of the denominator from the numerator since the bases were the same which is exactly what the identity is doing.

The total area of the given right trapezoidal prism is gotten as; A = 2592 sq.units

The formula to find the Surface Area of a Trapezoidal Prism is;

A = h(b + d) +l(a + b + c + d) unit square.

Where;

h = height

b and d are the lengths of the base

a + b + c + d is the perimeter

l is length

Thus;

A = 12(25 + 15) + 32(13 + 25 + 13 + 15)

A = 480 + 2112
