What is the length of the unknown leg

Mathematics
1 answer:
likoan [24]3 years ago
6 0

Answer:

6 mm

Step-by-step explanation:

Use the Pythagorean Theorem to solve for the unknown leg

a^{2} +b^{2}=c^{2}

Since we need to solve for a, we will manipulate the equation in terms of b and c → a=\sqrt{c^{2}-b^{2}  }

Here,  b = 7 mm and c = \sqrt{85} mm

Plugging these numbers into our equation gives us a=\sqrt{(\sqrt{85})^{2} -(7)^{2}  } →\sqrt{85-49} = \sqrt{36} = 6 mm

Which function in vertex form is equivalent to f(x) = 4 + x2 – 2x?
alisha [4.7K]

Answer:

option A

f(x) = (x – 1)2 + 3

Step-by-step explanation:

Given in the question a function,

f(x) = 4 + x² – 2x

<h3>Step 1</h3>

f(x) = 4 + x² – 2x

here a = 1

        b = -2

        c = 4

<h3>Step 2</h3>

x = -b/2a

h = -(-2)/2(1)

h = 2/2

h = 1

Step 3

Find k

k = 4 + 1² – 2(1)

k = 3

Step 4

To convert a quadratic from y = ax² + bx + c form to vertex form,

y = a(x - h)²+ k

y = 1(x - 1)² + 3

y = (x - 1)² + 3

The measurement of the angles of RSC are given by the expression in the table
Fudgin [204]

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in the triangle = 180°

Sum the 3 angles and equate to 180

31 + x + 4 + 3x + 9 = 180, that is

4x + 44 = 180 ( subtract 44 from both sides )

4x = 136 ( divide both sides by 4 )

x = 34

Thus

∠ S = x + 4 = 34 + 4 = 38°

∠ T = 3x + 9 = 3(34) + 9 = 102 + 9 = 111°
