Mathematics

Answer:

x = 7

Step-by-step explanation:

I think there may be other ways to do this ... but this is one I guess....

one angle= 90 ( given)

the other = 45 (given)

the third = 90 + 45 + a = 180

(all angles of triangles is 180 [angle sum property])

a = 180 - 135

= 45

The base angles are equal so that means it is a isoscles triangle. In isoscles triangle, two sides are equal , so

if one side is 7

the x is 7 too

(as it cant be the hypothenus)

I think this is right

A baseball has a diameter of 5.1 inches. Find the volume of the baseball. Round your answer to the nearest tenth. Use 3.14 for p

VladimirAG [237]

The volume of the baseball is 65.8

r = 1/2 d
r = 1/2 5.1
r = 2.505

V = 4/3 π r^3
V = 4/3 π 2.505^3
V = 65.8

I hope this helps!

Express the radical using the imaginary unit, iii. Express your answer in simplified form. \pm\sqrt{-34}=\pm± −34 =±plus minus

Yuki888 [10]

Answer:

$\pm \sqrt{-34} = \pm 5.831i$

Step-by-step explanation:

We have to express the given radical using imaginary unit.

$\sqrt{-34}$

We know that, imaginary unit:

$i = \sqrt{-1}$

We may solve the radical as:

$\pm \sqrt{-34}\\=\pm \sqrt{34\times -1}\\=\pm \sqrt{34}\times \sqrt{-1}\\=\pm \sqrt{34}\times i\\=\pm \sqrt{34}i\\\approx \pm 5.831i$

Evaluate the function for x = 3.5 f(x)=[2.5x] a 8.75 b 8 c 9

RSB [31]

Answer:

The correct option is a. 8.75.

Step-by-step explanation:

Given:

f(x)=[2.5x] .............................. (1)

Where;

x = 3.5

The function can be evaluated by substituting x = 3.5 into equation (1), we have:

f(3.5) = 2.5 * 3.5

f(3.5) = 8.75

This implies the value of the function is 8.75. Therefore, the correct option is a. 8.75.
