Answer:

-5 ≤ x ≤ 5

Step-by-step explanation:

If x^2 = 25

x = -5 or 5

BUT inequality

IF x is POSITIVE 5

You can square root both sides

x ≤ 5

IF x is NEGATIVE 5

You can divide both sides by -5

BUT switch inequality sign

This is because basically dividing both sides by negative

x ≥ -5

FINAL INEQUALITY

-5 ≤ x ≤ 5

The midpoint Riemann sum approximation of ∫64x3 1−−−−−√ⅆx using 4 subintervals of equal width is 9980

The midpoint Riemann sum approximation of ∫64x3 1−−−−−√ⅆx using 4 subintervals of equal width is calculated by summing the area of each subinterval under the midpoint of the interval.

The formula for the midpoint Riemann sum is given by:

Sum = (width of interval) * (height of midpoint)

For this problem, since the width of each interval is 16/4 = 4, the midpoint Riemann sum is calculated by:

Sum = 4 * (1 + (16/4)^3 + (32/4)^3 + (48/4)^3)

Substituting the values for each midpoint, we get the following equation:

Sum = 4 * (1 + 4^3 + 8^3 + 12^3)

This simplifies to:

Sum = 4 * (1 + 64 + 512 + 1728)

Therefore, the midpoint Riemann sum approximation of ∫64x3 1−−−−−√ⅆx using 4 subintervals of equal width is:

Sum = 4 * (2495)

Sum = 9980

The given statement If the thermal contrast between the cold pool and ascending updraft current within an MCS is large, we would expect a stronger rear inflow jet is False.

If the thermal contrast between the cold pool and ascending updraft current within a Mesoscale Convective System (MCS) is large, we would not necessarily expect a stronger rear inflow jet. The strength of the rear inflow jet is influenced by various factors, including the environmental conditions, vertical wind shear, and the organization and dynamics of the MCS itself.

While a strong thermal contrast between the cold pool and updraft can contribute to the development and maintenance of an MCS, it does not directly determine the strength of the rear inflow jet. The rear inflow jet is typically associated with the dynamic circulation within an MCS and is influenced by factors such as pressure gradients, outflow boundaries, and synoptic-scale weather patterns.

Therefore, the thermal contrast alone does not provide a conclusive indication of the strength of the rear inflow jet within an MCS. Other factors need to be considered to assess the intensity of the rear inflow jet.

Step-by-step explanation:

I took the test

The range at which Dan's car can go is 3.33 miles

A car's range is the distance it can travel with the current amount of fuel in the tank.

The vehicle calculates the range based on the amount of fuel, how the accelerator and brakes are used, and how quickly the car is travelling.

The range of a car can be measured in the unit of distance.

Therefore the range of a car can be calculated as;

R = distance per gallon/ number of gallon.

Dan's car is 40mpg and has 12 gallons in it's tank.

Therefore it's range = 40/12

= 3.33miles.

therefore the range of Dan's car is 3.33miles

Let's denote the total mass of the trading game cards as "M" in grams, and the number of packs of trading game cards as "P".

We can use the equation:

M = (1.71 g/card) * (16 cards/pack) * P

In this equation, (1.71 g/card) represents the mass of one card, (16 cards/pack) represents the number of cards in one pack, and P represents the number of packs.

Answer:

c)3/2(8/7)^x

Step-by-step explanation:

Evaluate the functions. 

1. Because 7/4 > 1 and the exponent is positive,

  the function does not decay.

2.Because 4/5 < 1 and the exponent is negative,

   the function does not decay.

3. Because 8/7 > 1 and the exponent is negative,

   the function decays.

4. Because 9/2 > 1 and the exponent is positive,

   the function does not decay.

A composite plot the functions verifies the answer.

If all the x's are exponents, then 3/2 (8/7)^-x is the only one that decays as x gets bigger.  That's because the base is greater than 1 and the x is negative.

please mark me brainliest :)

The only expression that is a decay function is f(x) = 2/3(4/5)^-x since 4/5 is less than 1

The standard form of an exponential equation is expressed as:

y = a(b)^x

where

a is the base

x is the exponent

b is the rate (determine whether the rate is growth or decay)

If the value of b is less than 1 then it is a decay function. The only expression that is a decay function is f(x) = 2/3(4/5)^-x since 4/5 is less than 1

It will take 2.3 weeks for the number of flowering plants to be equal to the number of weeds in the garden.

We set the two functions equal to each other and solve for t:

f(t) = w(t)

(2t + 14)/2 = e^(t-1) + 3

t + 7 = 2e^(t-1)

t + 7 = 2(e^t - e)

t + 7 = 2e^t - 2e

9 = 2e^t - 2t

11 = 2e^t

11/2 = e^t

ln (11/2) = t

t = ln (11/2)

t = 2.3025850929940459

t = 2.3

Therefore, it will take 2.3 weeks for the number of flowering plants to be equal to the number of weeds in the garden.

The standard deviation of the data set will increase by a factor of 10. This is because standard deviation measures how much variation or dispersion exists from the mean of a data set. Adding 10 to every value of the data set will increase the overall spread of the data and thus increase the standard deviation.  

To prove this mathematically, let's consider a data set A with mean M and standard deviation SD. Let's add 10 to every value of the data set to get a new data set B. The mean of set B is M+10 and the standard deviation of set B is SD'.   The formula for SD' is:  

SD':\(\sqrt{(x_{1} -(M+10))^{2} +(x_{2} -(M+10))^2+ (x_{3}-(M+10))^2 +...+ (x_{n}-(M+10))^2)/n }\) We can simplify this by substituting the values for the xi:

 SD' =\(\sqrt{(((x_{1}-M-10)^2 + (x_{2}-M-10)^2 + (x_{3}-M-10)^2 +...+ (x_{n}-M-10)^2)/n) }\)  Now let's consider the original data set A and its standard deviation SD:

 SD =\(\sqrt{(((x_{1}-M)^2 + (x_{2}-M)^2 + (x_{3}-M)^2 +...+ (x_{n}-M)^2)/n) }\) ,We can substitute the values for xi in this formula as well:  

SD= \(\sqrt{ (((x_{1}-M-10)^2 + (x_{2}-M-10)^2 + (x_{3}-M-10)^2 +...+ (x_{n}-M-10)^2)/n)}\)  If we compare SD and SD', we can see that they are identical, except that the value of M has been replaced with M+10. This means that when we add 10 to every value of the data set, the standard deviation increases by a factor of 10.

The direction vector of l is <2, 5, 3>, so the projection of the vector from (0, 0, 0) to (x, y, z) onto this direction vector is:

proj<0, 0, 0>(2, 5, 3)/||<2, 5, 3>||^2 * <2, 5, 3> = <0, 0, 0>

To find a point on the line l that is parallel to it, we simply need to choose any value of t and plug it into the parametric equations. Let's choose t = 1, then we have:

x = 5 + 2(1) = 7

y = 5(1) - 4 = 1

z = 3 + 3(1) = 6

So P = (7, 1, 6) is a point on the line l that is parallel to it.

To find a point Q at which the line and l are perpendicular, we need to find the point on l that is closest to the given point (0, 0, 0). This can be done by finding the projection of the vector from (0, 0, 0) to a point on l onto the direction vector of l. The direction vector of l is <2, 5, 3>, so the projection of the vector from (0, 0, 0) to (x, y, z) onto this direction vector is:

proj<0, 0, 0>(2, 5, 3)/||<2, 5, 3>||^2 * <2, 5, 3> = <0, 0, 0>
