Hhhheeeeellllllpppp no 13 and 14​
laila [671]

Answer:

13. B. 24 cm²

14. y = 5⅝ (none of the options is correct)

Step-by-step explanation:

13. The figure is a trapezoid

Area of the trapezoid = ½(a + b)h

Where,

a = 3 cm

b = 5 cm

h = 6 cm

Area = ½(3 + 5)6

= ½(8)6

= 4*6

= 24 cm²

14. Area of the triangle = ½*b*h

The area is given to be 45 cm²

base (b) = 16 cm

height (h) = y

Plug in the values and solve for y

45 = ½*16*y

45 = 8y

Divide both sides by 8

45/8 = 8y/8

45/8 = y

5⅝ = y

y = 5⅝ (none of the options is correct)

Describe the transformation that takes f(x)=x+1 to g(x) = -x+4. Will Mark Brainliest.​
lions [1.4K]

Answer:

Reflection across y axis

Translate up by 3 units

Step-by-step explanation:

Given

f(x) = x + 1

g(x) = -x + 4

Required

Describe the transformation from f(x) to g(x)

First, take a reflection of f(x) across the y axis.

So f(x) becomes f(-x)

f(x) = x + 1 when reflected

f(-x) = -x +1

Next, translate f(-x) up by 3 units to give g(x)

g(x) = f(-x) + k

Where

k = 3

f(-x) = -x +1

g(x) = -x + 1 + 3

g(x) = -x + 4

Hence, the transformation from f(x) to g(x) includes:

Reflection across y axis

Translate up by 3 units

Tyler bought 20 shares of Wal-Mart at $48.80. A year later, he bought 20 more shares at $54.60. He later sold all of his shares
NARA [144]
He bought last year and year later total is $104.3

Each share he sold 62.80 with tax is 0.03

62.80x1.03= $64.684 for each share
So there are 40 shares

64.684 x 40= $2587.36
