What is exponential form of -10 × -10​

Answer:

  y = -4/3x + 3

Step-by-step explanation:

3x − 4y = −8

-4y = -3x - 8

y = 3/4x + 2

slope m = 3/4

perpendicular version of it is opposite inverse: -4/3

y-intercept through point (0, 3):

y = mx + b

3 = -4/3(0) + b

b = 3

Use the perpendicular slope with b from above to form new perpendicular equation of line:

y = mx + b

y = -4/3x + 3

The correlation will not be −0.44 based solely on the slope of the regression line. (option c).

Let X and Y be the vectors of standardized values of X and Y, respectively, for all the subjects. Then, the least-squares regression line can be written as:

Y = βX

where β is the slope of the regression line. To find the intercept, we need to solve for the value of Y when X = 0:

Y = β(0) = 0

This means that the intercept of the regression line in the standardized coordinate system is 0. To find the intercept in the original coordinate system, we need to transform this point back using the formula for standardization:

Y = σY(Y) + μY

where σY is the standard deviation of Y and μY is the mean of Y. Since y = 0, we have:

Y = σY(0) + μY = μY

So, the intercept of the regression line in the original coordinate system is equal to the mean of Y. Therefore, we cannot conclude that the intercept will be −0.44 or 1.0.

Hence the correct option is (c).

Step-by-step explanation:

radius of the circle is sqrt(3)x.

The radius of the circle can be found by using the Pythagorean Theorem. The side lengths of each equilateral triangle created by the diagonals is 2x, so the hypotenuse of the triangle is sqrt(3)x. Since the hypotenuse of each triangle is the same as the radius of the circle, the radius of the circle is sqrt(3)x.

Step-by-step explanation:

The height of the soccer ball when it was hit is 3 feet. It takes approximately 0.66 seconds for the soccer ball to reach its maximum height. The maximum height is approximately 10.89 feet.

To solve the given problem, we'll use the provided quadratic function h(t) = -16t^2 + 21t + 3, which represents the height of the soccer ball at time t.

(a) To find the height of the soccer ball when it was hit, we need to evaluate h(0) since t represents the time in seconds. Substituting t = 0 into the function, we get:

h(0) = -16(0)^2 + 21(0) + 3 = 3

Therefore, the height of the soccer ball when it was hit is 3 feet.

(b) To determine the time it takes for the soccer ball to reach its maximum height, we need to find the vertex of the parabolic function, which represents the maximum point. The time at the vertex can be found using the formula:

t = -b / (2a)

For the function h(t) = -16t^2 + 21t + 3, a = -16 and b = 21.

t = -21 / (2 * -16) ≈ 0.66 seconds (rounded to 3 decimal places).

(c) The maximum height can be found by substituting the time from part (b) back into the function. Evaluating h(0.66), we get:

h(0.66) = -16(0.66)^2 + 21(0.66) + 3 ≈ 10.89 feet (rounded to 3 decimal places).

Therefore, the maximum height of the soccer ball is approximately 10.89 feet.

Answer:

m<1 = 51°

m<2 = 18°

m<3 = 123°

Hope this helps

Answer:

angle 1: 51 angle 3: 123, angle 2: 18, angle 4: 39

Step-by-step explanation:

First lets find angle 1: We can see that the triangle already has 2 angles filled in, so remember that triangles are 180 degrees total. Now we take 72+57=129 degrees. Now 180-129=51 degrees that were missing.

Angle 3: angle 57 and angle 3 will add up to 180 degrees, because it is a line. So all we need to do is subtract 180-57=123 degrees.

Angle 2: We see that there is a right angle on that corner, so we already have 72 degrees. Take 90-72= 18 degrees.

Angle 4: We know angles 3 and 2, so add them up: 123+18=141. Triangles add up to 180 degrees, so 180-141=39 degrees for the missing angle.

Answer:

Step-by-step explanation:

The number which makes \(5x=10\) true is 2.

\(5(2)=10\)

\(10=10\)

Therefore, 2 is the true value for this. But, lets check an equation like this.

\(\frac{5x}{3}=10\)

We can use algebraic methods to solve this, first multiply 3

\(5x=30\)

Divide by 5

\(x=6\)

Because  6 > 2, the number 2 does not make the two equations equivalent.

A

Step-by-step explanation:

The claim we need to check is that 16 is the 50% of 36.

Recall that if we add 50% and 50%, we should end up with 100%. In our case, we have that our 100% is 36. So, if it was true that 16 is the 50% of 36, then it should happen that if we add 16 with itself, we should get 36.

Note that

Since 16+16 is not 36, it is not true that 16 is the 50% of 36.

The probability of winning by picking the number 30 in roulette is 1/38.

In the game of roulette, the wheel consists of 38 spaces, with numbers 0 through 36 and an additional space marked 00. When you pick a specific number, such as 30, the probability of that number coming up on the wheel can be determined by calculating the ratio of favorable outcomes to the total number of possible outcomes.

In this case, there is only one favorable outcome, which is the ball landing on the number 30. The total number of possible outcomes is 38 since there are 37 numbered spaces (0 through 36) and one additional space for 00. Therefore, the probability of winning by picking the number 30 is 1 out of 38.

To put it simply, if you were to play roulette many times, you would expect the number 30 to come up approximately once every 38 spins on average. This probability remains the same for each individual spin, as each spin of the roulette wheel is an independent event.

Step-by-step explanation:

x + 3 / 0 = y / 6 = z - 2 / 3 is the required set of parametric equation and symmetric equation of line.

Given the point (-3, 0, 2) and the vector v = 6j + 3k, we need to find the set of parametric equation and symmetric equation of the line through the point and parallel to the given vector.

Let the line be L and a point on the line be P(x, y, z).

Then, the vector from (-3, 0, 2) to P is given by

r = OP = i(x + 3) + jy + k(z - 2)

Since L is parallel to the vector v = 6j + 3k, the direction ratios of L are proportional to the components of v. Thus, the direction ratios of L are 0, 6, and 3.

Therefore, the parametric equations of L are:

x + 3 = 0 ⇒ x = -3y = tz - 2 = 3t + 2

where t is a parameter, and the symmetric equations are x + 3 / 0 = y / 6 = z - 2 / 3. This is the required answer.

The age of a movie attendee with a z-score of -1.2 is approximately 24.2 years old (rounded to the nearest tenth).

We can use the standard normal distribution to find the age of a movie attendee with a z-score of -1.2:

z = (x - mu) / sigma

where z is the z-score, x is the age we want to find, mu is the mean age, and sigma is the standard deviation.

Rearranging this formula, we get:

x = mu + z * sigma

Substituting the given values, we get:

x = 32 + (-1.2) * 6.2

x = 24.16

Therefore, the age of a movie attendee with a z-score of -1.2 is approximately 24.2 years old (rounded to the nearest tenth).

Step-by-step explanation:

Shawna lives 10/3 miles farther from work compared to her brother.

This can also be expressed as a mixed fraction: 3 1/3 miles.

To determine how much farther Shawna lives from work compared to her brother, we need to find the difference between the distances they live from their respective workplaces.

Shawna lives 6 5/12 miles from the hospital, which can be written as a mixed fraction: 6 + 5/12 = 77/12 miles.

Her brother lives 3 1/12 miles from the law firm, which can be written as a mixed fraction: 3 + 1/12 = 37/12 miles.

To find the difference in distance, we subtract the distance her brother lives from the distance Shawna lives:

77/12 - 37/12

To subtract fractions with the same denominator, we subtract the numerators and keep the common denominator:

(77 - 37)/12

Simplifying the numerator:

40/12

Now, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 4:

40/12 = (4 \(\times\) 10)/(4 \(\times\) 3) = 10/3

Therefore, Shawna lives 10/3 miles farther from work compared to her brother. This can also be expressed as a mixed fraction: 3 1/3 miles.

Thus, Shawna lives 3 1/3 miles farther from work than her brother.
