Find x.______________a0

Mathematics
1 answer:
velikii [3]3 years ago
4 0

Answer:

x=4

Step-by-step explanation:

Before we find x, we need to set up this triangle a little more. We need to find the triangle's altitude before we can solve for x. We will use the heartbeat method to find the altitude.

Let altitude = y; solve for y:

\frac{2}{y}=\frac{y}{6}

y^2=12

y=\sqrt{12}

y=2\sqrt{3}

Now that we know the altitude, we can use the Pythagorean Theorem to find the hypotenuse (x).

a^2+b^2=c^2

2^2+(2\sqrt{3})^2=c^2

4+12=c^2

c^2=16

c=4

Since c and x are the same; c is just the hypotenuse in the Pythagorean Theorem.

x=4

For f(x)=3x+1 and g(x)=x squared - 6 find (f- g)(x)
saveliy_v [14]
It helps to first clarify that the notation (f - g)(x) simply means f(x) - g(x). Given that, let's look at our f(x) and our g(x) here, and use their definitions to find their difference.

f(x)=3x+1\\g(x)=x^2-6

When we're taking (f - g)(x), we simply substitute the expression 3x + 1 for f(x) and the expression x² - 6 for g(x) to obtain:

(3x+1)-(x^2-6)=3x+1-x^2+6

Or, ordering the polynomial from highest power to lowest and combining the constants:

-x^2+3x+7

Edit: By request, here's what would happen if you had something instead like:

(f\times g)(x)

In this case, you'd have to *multiply* the two function expressions together. Here's what that would look like:

(3x+1)(x^2-6)

Using the distributive property, we can distribute the expression 3x+1 to the terms x^{2} and -6:

(3x+1)x^2-(3x+1)6

Distributing again, we get:

3x(x^2)+x^2-3x(6)+6=3x^3+x^2-18x+6

And we're done.

In ΔEFG, f = 42 inches, e = 39 inches and ∠E=43°. Find all possible values of ∠F, to the nearest degree.\
zavuch27 [327]

Answer:

The angle F = 47.25°

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that f =42inches  and  e = 39 inches

Given that ∠E = 43°

By using sine rule

                 \frac{a}{sinA} = \frac{b}{sinB} = \frac{C}{sinC}  = 2R

                \frac{e}{sinE} = \frac{f}{sinF}

 ⇒          \frac{39}{sin43} = \frac{42}{sinF}

  Cross multiplication , we get

⇒       39 sin F = 42 × sin 43°

             sin F = \frac{42 X 0.68199}{39}

⇒           sin F = 0.734459

<u><em>Step(ii):-</em></u>

⇒       sin⁻¹ (sin F)= sin ⁻¹ ( 0.734459)

⇒            F = 47.25

The angle F = 47.25°
