Answer:

6.5

Step-by-step explanation:

{6}^{2}  +  {2.5}^{2}  =  {x}^{2}  \\ 36 + 6.25 =  {x}^{2}  \\ 42.25 =  {x}^{2}  \\  \\ x =  \sqrt{42.25}  \\ x = 6.5

Use the Pythagorean theorem.

It's easy if you use a calculator.

The answer you are looking for is 6.5.

To find this answer, you use the equation a² + b² = c², where c is the hypotenuse (the side with x in this case).

Next, fill in a and b with the two values given. Doing so will make the equation say 6² + 2.5² = c².

Now you solve for c.

6² = 36 and 2.5² = 6.25. (36 + 6.25 = c²)

36 + 6.25 = 42.25. (42.25 = c²)

√42.25 = 6.5. (6.5 = c)

Thus meaning 6.5 is the answer. I hope this helps!

Answer:  See Below

<u>Step-by-step explanation:</u>

NOTE: You need the Unit Circle to answer these (attached)

5) cos (t) = 1

Where on the Unit Circle does cos = 1?

Answer: at 0π (0°) and all rotations of 2π (360°)

In radians:     t = 0π + 2πn

In degrees:   t = 0° + 360n

******************************************************************************

6)\quad sin (t) = \dfrac{1}{2}

Where on the Unit Circle does   sin = \dfrac{1}{2}

<em>Hint: sin is only positive in Quadrants I and II</em>

\text{Answer: at}\  \dfrac{\pi}{6}\ (30^o)\ \text{and at}\ \dfrac{5\pi}{6}\ (150^o)\ \text{and all rotations of}\ 2\pi \ (360^o)

\text{In radians:}\ t = \dfrac{\pi}{6} + 2\pi n \quad \text{and}\quad \dfrac{5\pi}{6} + 2\pi n

In degrees:    t = 30° + 360n  and  150° + 360n

******************************************************************************

7)\quad tan (t) = -\sqrt3

Where on the Unit Circle does    \dfrac{sin}{cos} = \dfrac{-\sqrt3}{1}\ or\ \dfrac{\sqrt3}{-1}\quad \rightarrow \quad (1,-\sqrt3)\ or\ (-1, \sqrt3)

<em>Hint: sin and cos are only opposite signs in Quadrants II and IV</em>

\text{Answer: at}\  \dfrac{2\pi}{3}\ (120^o)\ \text{and at}\ \dfrac{5\pi}{3}\ (300^o)\ \text{and all rotations of}\ 2\pi \ (360^o)

\text{In radians:}\ t = \dfrac{2\pi}{3} + 2\pi n \quad \text{and}\quad \dfrac{5\pi}{3} + 2\pi n

In degrees:    t = 120° + 360n  and  300° + 360n

Find the total surface area
Sindrei [870]

Answer:

298 cm^2.

Step-by-step explanation:

There are 3 pairs of faces of equal area.

Area of top = 7 * 11.  So it's  2 * 7 * 11 = 154.

Area of a smaller side  = 7 * 4 so we have 2*28 = 56 .

Area of larger side = 4*11 so it's  2*44 = 88.

Total surface area = 154 + 56 + 88

= 298.

Which is an equation of the line that passes through the point (1, 4) and has a slope of 3?
Varvara68 [4.7K]
So an equation of any line is y=mx+b.
We know that the m, or slope, equals 3.
y=3x+b
Now we find the b, or the y-intercept, by substituting the x and y values into their places.
4=3*1+b
4=3+b
b=1
Now that we have the y-intercept, we just substitute the m and b into the equation and receive our final answer:
y=3x+1
