Answer:

[tex]\boxed {\boxed {\sf x \approx 105.3}}[/tex]

Step-by-step explanation:

To solve for x, remember the right triangle trigonometry ratios (soh-cah-toa).

If we look at the angle given (θ), then we see that 36 is adjacent or next to the 70° angle. x is the hypotenuse because it is opposite the right angle. So, we have to use cosine (adjacent and hypotenuse).

[tex]cos (\theta)=\frac {adjacent}{hypotenuse}[/tex]

[tex]cos(70)=\frac{36}{x}[/tex]

Cross multiply. (Multiply the first numerator by the second denominator. Then, multiply the first denominator by the second numerator).

[tex]\frac{cos(70)}{1}=\frac{36}{x}[/tex]

[tex]cos(70)*x= 36[/tex]

Since we want to solve for x, we must isolate the variable. Divide both sides by the cosine of 70.

[tex]\frac{cos(70)*x}{cos(70)}=\frac{ 36}{cos(70)}\\x= 105.2569584[/tex]

Round to the nearest tenth. The 5 in the hundredth place tells us to round the 2 to a 3.

[tex]x \approx 105.3[/tex]

Answer:

Step-by-step explanation:

add and complete

The x-intercepts of the function f(x) are:

Left x-intercept: (-3, 0)

Right x-intercept: (7, 0)

Given is a function, f(x) = -2(x + 3)(x - 7).

We need to find the x-intercept of the function,

To find the x-intercepts of the function f(x), we set f(x) equal to zero and solve for x:

-2(x + 3)(x - 7) = 0

Now, we can use the zero product property, which states that if a product of factors is equal to zero, then at least one of the factors must be zero.

So, we have two cases to consider:

Case 1: x + 3 = 0

Solving this equation, we subtract 3 from both sides:

x = -3

Case 2: x - 7 = 0

Solving this equation, we add 7 to both sides:

x = 7

Therefore, the x-intercepts of the function f(x) are -3 and 7.

Writing them as ordered pairs, we have:

Left x-intercept: (-3, 0)

Right x-intercept: (7, 0)

The solution of the given equation will be 2√5x(√2-1).

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

The expression will be solved as below:-

= √5x ( √8x² - 2√x)

= √5x ( 2√2x - 2√x)

= √5x(√2-1)(2√x)

= 2√5x(√2-1).

Answer:

The ball height is 11 meters at t = 0.59 seconds and t = 3.41 seconds.

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

[tex]ax^{2} + bx + c, a\neq0[/tex].

This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:

[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]

[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]

[tex]\Delta = b^{2} - 4ac[/tex]

The height of the ball after t seconds is given by:

[tex]h(t) = 1 + 20t - 5t^2[/tex]

Find all values of t for which the ball's height is 11 meters.

This is t for which [tex]h(t) = 11[/tex]. So

[tex]h(t) = 1 + 20t - 5t^2[/tex]

[tex]11 = 1 + 20t - 5t^2[/tex]

[tex]5t^2 - 20t + 10 = 0[/tex]

Simplifying by 5

[tex]t^2 - 4t + 2 = 0[/tex]

Which means that [tex]a = 1, b = -4, c = 2[/tex]

[tex]\Delta = (-4)^2 - 4(1)(2) = 8[/tex]

[tex]t_{1} = \frac{-(-4) + \sqrt{8}}{2} = 3.41[/tex]

[tex]t_{2} = \frac{-(-4) - \sqrt{8}}{2} = 0.59[/tex]

The ball height is 11 meters at t = 0.59 seconds and t = 3.41 seconds.

Answer:

(-5 1 0 0) and (-3 0 1 0)

Step-by-step explanation:

Based on my memory,  you can use the dot product to find orthogonality meaning

u1 . u2 = 0

In this case, we let u be the arbitrary vector represented by (x y z w)

u . (1 5 3 0) can be expressed as an equation given by:

{(x y z w) | x + 5y + 3z  + 0w= 0}

We solve this equation letting y = s and z = t and x = -5s -3t

Reconstruct this according to their variable will give

(-5 1 0 0)s + (-3 0 1 0)t = 0

So the basis vectors are (-5 1 0 0) and (-3 0 1 0).

Let c1 and c2 be arbitrary constants:

if you solve for c1(-5 1 0 0) + c2(-3 0 1 0) = 0

c1 and c2 should have only trivial solution, which proves its

linear independence and so it forms a basis vector space.
