Answer:

y^ ⁻⁹/⁴ * z^⁽⁻³⁾

Step-by-step explanation:

(Y^3 z^4)^(-3/4) = (y^3)^(-3/4) * (z^4)^(-3/4)

= y^3* ⁽⁻³/⁴⁾ * z^4 *⁽⁻³/⁴⁾

=y^ ⁻⁹/⁴ * z^⁽⁻³⁾

How would you solve this(what is the equation of the line that passes through the point (3,4) and has a slope of -2/3?)//delta m

andre [41]

Answer:

$y = -\frac{2}{3}x + 6$

Step-by-step explanation:

y = mx + b is the formula for slope intercept. What we can do is plug in the slope and coordinate points to find the y-intercept.

4 = $-\frac{2}{3}$ (3) + b

-2/3 times 3 is -2 so you can fill that in place.

4 = -2 + b

6 = b

So the y-intercept is 6 now we can complete the equation.

$y = -\frac{2}{3}x + 6$

Hope that helps and have a great day!

An education firm measures the high school dropout rate as the percentage of 16 to 24 year olds who are not enrolled in school a

posledela

Answer:

The value of the test statistic $z = -0.6606$

Step-by-step explanation:

From the question we are told that

The high dropout rate is $\mu = 6.1$ % $= 0.061$

The sample size is $n = 1000$

The number of dropouts $x = 56$

The probability of having a dropout in 1000 people $\= x = \frac{56}{1000} = 0.056$

Now setting up Test Hypothesis

Null $H_o : p = 0.061$

Alternative $H_a : p < 0.061$

The Test statistics is mathematically represented as

$z = \frac{\= x - p}{\sqrt{\frac{p(1 -p)}{n} } }$

substituting values

$z = \frac{0.056 - 0.061}{\sqrt{\frac{0.061(1 -0.061)}{1000} } }$

$z = -0.6606$

If f(x) = 3x - 1 and g(x) = x + 2, find (1-9)(x).

Studentka2010 [4]

Answer:

$(f-g)(x)=2x-3$

Step-by-step explanation:

<em>The correct question is</em>

If f(x)=3x-1 and g(x)=x+2, find (f-g)(x)

we know that

(f-g)(x) is equal to subtract the function g(x) from the function f(x)

$(f-g)(x)=f(x)-g(x)$

substitute the given functions

$(f-g)(x)=(3x-1)-(x+2)$

Remove the parenthesis

$(f-g)(x)=3x-1-x-2)$

Combine like terms

$(f-g)(x)=2x-3$

Which statements accurately describe the function f(x) = 3(16)^3/4? Check all that apply.

uysha [10]

Answers:

These are the statements that apply:

The initial value is 3.

The range is y >0.

The simplified base is 8.

Explanation:

1) Given expression:

$f(x)=3(16)^{\frac{3}{4} x$

2) Check every statement:

a) The initial value is 3?

initial value ⇒ x = 0 ⇒

$f(0)=3(16)^{0}=3(1)=3$

∴ The statement is right.

b) The initial value is 48?

Not, as it was already proved that it is 3.

c) The domain is x > 0?

No, because the domain of the exponential functions is all the Real numbers.

d) The range is y > 0?

That is correct, the exponential function is continuous, and monotonon increasing.

The limit when x → - ∞ is zero, but y never reaches zero, and the limit when x → ∞ is + ∞, meaning that the range is y > 0.

e) The simplified base is 12?

This is how you simplify the base:

$3(16)^{\frac{3}{4} x}=3{{(16}^{(3/4)})}^x=3(16^{3/4}})^{x}=3((2^4)^{3/4})^x=3(2^3)^x=3(8)^x$

Which shows that the simplified base is 8 (not 12).

f) The simplified base is 8?

Yes; this was just proved.
