What is the area of the triangle in centimeters squared?

Mathematics
1 answer:
Rashid [163]3 years ago
7 0

Answer:

A = 112cm²

Step-by-step explanation:

Area of a triangle = (bh) / 2

b = base length and h  = height

The triangle shown has a given base length of 14cm and a given height of 16cm

Hence area = ( 16 * 14 ) / 2

16 * 14 = 224

224 / 2 = 112

A = 112cm²

Graph y = 3x - 3 and label the x- and y-intercepts. My answer: (0,3)
Lesechka [4]
The slope-intercept form of the linear function is y = m x + b , where m is the slope and b is y-intercept.
Here we have: y = 3 x - 3
a ) When y = 0
0 = 3 x - 3
- 3 x  = - 3
x = ( - 3 ) : ( - 3 ) 
x = 1
When x = 0
y = 3 * 0 - 3 
y = - 3
So x - intercept is ( 1, 0 ) and y-intercept is ( 0, - 3 ).
b ) The slope:
m = ( y2 - y1) / ( x2 - x1 ) = 
= ( - 3 - 3 ) / ( 5- 7 ) = ( - 6 ) /( - 2 ) = 6 / 2 = 3
Answer: The slope m = 3 .

Mario was making cookies. He mixed 2½ cups of flour, 1¼ cups of sugar and ½ cup of brown sugar together in a bowl. How many cups
STatiana [176]

Answer:

4 1/4

Step-by-step explanation:

2 1/2 + 1 1/4 + 1/2 = 5/2 + 5/4 + 1/2

LCM = 4

5/2 x 2/2 = 10/4

5/4 = 5/4

1/2 x 2/2 = 2/4

10/4 + 5/4 + 2/4 = 17/4

                          = 4 1/4

Therefore he put 4 1/4 cups altogether.

Solve:<br> -2/3 a - 6 = 12 <br> what is a
Hitman42 [59]

Answer:

a = - 27

Step-by-step explanation:

- \frac{2}{3} a - 6 = 12 ( add 6 to both sides )

- \frac{2}{3} a = 18 ( multiply both sides by 3 to clear the fraction )

- 2a = 54 ( divide both sides by - 2 )

a = - 27

Which of these functions has an inverse function? Select all that apply.
ElenaW [278]

ANSWER

y=x

y=x³

EXPLANATION

A function, f(x) has an inverse if and only if

f(a) = f(b)   \Rightarrow \: a = b

Thus, the function is one to one.

For y=x or

f(x) = x

f(a) = f(b)   \Rightarrow \: a = b

Hence this function has an inverse.

For the function y=x² or f(x)=x².

f(a) = f(b)   \Rightarrow \:  {a}^{2} =  {b}^{2} \Rightarrow \: a =  \pm \: b

This function has no inverse on the entire real numbers.

For the function y=x³ or f(x)=x³

f(a) = f(b)   \Rightarrow \:  {a}^{3} =  {b}^{3} \Rightarrow \: a = b

This function also has an inverse.

For y=x⁴ or f(x) =x⁴

f(a) = f(b)   \Rightarrow \:  {a}^{4} =  {b}^{4} \Rightarrow \: a =  \pm \: b

This function has no inverse over the entire real numbers.
