If f(x) is an exponential function where f(-1.5) 26 and

mariarad [96]

Answer:

$f(10) = 1147.25$

Step-by-step explanation:

Given

$f(-1.5) = 26$

$f(5.5) = 7$

Required

f(10)

An exponential function is represented as:

$f(x) = ab^x$

$f(-1.5) = 26$ impleies that:

$26 = ab^{-1.5}$ --- (1)

$f(5.5) = 7$ implies that

$7 = ab^{5.5}$ --- (2)

Divide (2) by (1)

$26/7 = ab^{-1.5}/ab^{5.5}$

$3.71429 = b^{-1.5+5.5}$

$3.71429 = b^{4}$

Take 4th root

$b = 1.39$

Substitute $b = 1.39$ in $26 = ab^{-1.5}$

$26 = a * 1.39^{-1.5}$

$26 = a * 0.6102$

Solve for (a)

$a = 26/0.6102$

$a = 42.61$

f(10) is calculated as:

$f(10) = ab^{10}$

$f(10) = 42.61 * 1.39^{10}$

$f(10) = 1147.25$

What is the approximate value of q in the equation below?

gayaneshka [121]

Given:

The given equation is $q+\log _{2}(6)=2 q+2$

We need to determine the approximate value of q.

Value of q:

To determine the value of q, let us solve the equation for q.

Hence, Subtracting $\log _{2}(6)$ on both sides of the equation, we get;

$q=2 q+2-\log _{2}(6)$

Subtracting both sides of the equation by 2q, we have;

$-q=2-\log _{2}(6)$

Dividing both sides of the equation by -1, we have;

$q=\log _{2}(6)-2$

Now, substituting the value of $log_2(6)=2.585$ , we have;

$q=2.585-2$

Subtracting the values, we get;

$q=0.585$

Thus, the approximate value of q is 0.585

Hence, Option C is the correct answer.

What is the slope of -y=-x+6

Katarina [22]

Answer:

m = 1
b = -6

Step-by-step explanation:

We know that:

-y = -x + 6
y = mx + b

First, we need to change the 'y' sign.

=> -y = -x + 6
=> y = x - 6

Now, let's compare both of the equations to find slope.

=> (y = x - 6) = (y = mx + b)

We can see that the slope is 1 and the y-intercept is -6.

Conclusion:

Therefore:

m = 1
b = -6

Hoped this helped.
