Solve for X and round to the nearest hundredths

Mathematics
1 answer:
Evgesh-ka [11]4 years ago
8 0

Answer:

x = 44.50

Step-by-step explanation:

Pythagorean Theorem: a^{2} + b^{2} = c^{2}

Here, a (or b, it doesn't matter) = 9 and c = 24.

9^{2} +b^{2} =24^{2}

81+b^{2} =576

b^{2} =495 (subtract 81 from both sides)

b ≈ 22.249 (apply square root to both sides)

b is half of x, so 2

x ≈ 44.50

Answer:

(x-8) (x+7)

Step-by-step explanation:

x^2 -x-56

We want to factor this problem.

What two numbers multiply to negative 56 and add to -1

-8 *7 = -56

-8+7 = -1

We can use -8 and 7

(x-8) (x+7)

Check:

FOIL

first: x*x =x^2

outer: 7x

inner:-8x

last: -8*7 = -56

Add this together

x^2 +7x-8x -56 = x^2 -x-56

Olivia kicks a soccer ball from the ground with an initial vertical velocity of 15 m/s. Which equation can be used to find the t
babunello [35]

Answer:

The answer is below

Step-by-step explanation:

Motion shows the change in the position of an object over time. This change is showed in terms of displacement, distance, velocity, acceleration, time and speed. The equations of motion shows this relationship.

Since the soccer ball is kicked up with an initial velocity (u) of 15 m/s, the acceleration due to gravity (g) acts on the ball. If the ball is kicked at an angle Θ, the time t it takes for the ball to reach the ground is:

t=\frac{2u*sin(\theta)}{g} \\\\t=\frac{2(15)*sin(\theta)}{g} \\\\t=\frac{30*sin(\theta)}{g} \\\\If\ it\ is\ kicked\ vertical\ then\ \theta=90^0,hence:\\\\t=\frac{30*sin(90)}{g}= \frac{30}{g }

Write the equivalent of the fraction using a denominator of 52. 2/13
il63 [147K]

The equivalent of the fraction using a denominator of 52. 2/13 is 261/65.

A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, 1 is the remainder. So, a mixed fraction is a combination of a whole number and a proper fraction.

The given question is a mixed fraction which can then be sorted in two fractions shown as below

52. 2/13

= (52 + 0.2)/13

=52/13 + 0.2/13

= 4 + 1/65

= (65x4 + 1)/65

= 261/65

Thus the equivalent of the fraction using a denominator of 52. 2/13 is 261/65.

If a function is symmetric over the line x = 2, what kind of function could it be? A. absolute value B. cubic C. exponential D.
Anon25 [30]

Answer:

A. Absolute value.

Step-by-step explanation:

We are asked to determine the type of function, if it is symmetric over the line x=2.

We know that a line of form x=a represents an equation of a vertical line that crosses x-axis at point (2,0) parallel to y-axis.

We know that a cubic function is symmetric about origin, while an exponential function has no symmetry.

A rational function is not necessarily symmetric to y-axis.

We know that an absolute value function is symmetric about y-axis, so our given function will be symmetric to the line x=2 and option A is the correct choice.
