Answer:

7.5

Step-by-step explanation:

The area of a triangle is found by the formula A=1/2bh, where b is the base length, and h is the height. If we count the squares, we can find that the base length of the triangle is 3 units, and the height is 5 units. If we plug those numbers into the equation to get A=1/2*3*5, we can solve to get A=7.5

Express answer in exact form.

Fiesta28 [93]

A chord and a radius form an equilateral triangle.
The area of the larger segment is:
A = 5/6 r² π + r²√3/2 = 5/6 · 64 · 3.14 + 32 · 1.73 =
= 167.47 + 55.36 = 222.83 in²

What is the answer and how to you solve it as easy as possible

Gnom [1K]

Answer:

A = 504inch

Step-by-step explanation:

Formula = A = 2(wl + hl + hw)

or A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

2wl = 6inch × 12inch = 72inch × 2 = 144inch

2lh = 12inch × 10inch = 120inch × 2 = 240inch

2hw = 10inch × 6inch = 60inch × 2 = 120inch

Then add all

144inch + 240inch + 120inch = 504inch

A = 504inch

Write a slope-intercept equation for a line perpendicular to f(x) = −2x + 4 and

Fittoniya [83]

Answer:

$y = \frac{1}{2} x + 1$

Step-by-step explanation:

<u>Slope-intercept form</u>

y= mx +c, where m is the slope and c is the y-intercept

f(x)= -2x +4

Let's rewrite this function into an equation, in the slope-intercept form.

y= -2x +4

Slope= -2

The product of the slopes of perpendicular lines is -1.

Let the slope of the perpendicular line be m.

m(-2)= -1

m= ½

y= ½x +c

To find the value of c, substitute a pair of coordinates into the equation.

When x= -4, y= -1,

-1= ½(-4) +c

-1= -2 +c

c= -1 +2

c= 1

Thus, the equation of the line is y= ½x +1.
