The following points are the vertices of a traingle: (0,4), (4,0), (-4,0)

1 answer:

7 0

B. A = 1/2 b h
A = 1/2 (8)(4)
A = 16 square units

a. y = x + 4, -4 less than or equals x less than or equals
y = -x + 4, 0 less than or equals x less than or equals 4
y = 0 , -4 less than or equals x less than or equals 4

1 in/2.54 cm = 90 in/? cm

nirvana33 [79]

1/2.54 = 90/x

Cross multiply
(1)x = (2.54)(90)

x would equal 228.6

The answer would be 90 in/ 228.6 cm.

¿cuál es el vértice de una parábola que corta los ejes en los puntos (-1,0) , (5,0), (0,-10) ?

kvasek [131]

Answer:

vertex: (2,-18)

Step-by-step explanation:

y = ax² + bx + c

(-1,0) : a - b + c = 0 ...(1)

(5,0) : 25a +5b +c = 0 ...(2)

(0,-10): 0a + 0b + c = -10 c=-10

(1) x5: 5a - 5b + 5c = 0 ...(3)

(2)+(3): 30a + 6c = 0 30a = -6c = 60 a = 2

(1): 2 - b -10 = 0 b = -8

Equation: y = 2x² - 8x -10 = 2 (x² -4x +4) - 18 = 2(x-2)² -18

equation: y = a(x-h)²+k (h,k): vertex

vertex: (2,-18)

Couldn't do this one help needed

Paladinen [302]

Answer:

shown below.

Step-by-step explanation:

v = 150 since 180 - 30

for w we need 2y and x. the base angles of the triangle are 30 and 50 therefore x = 100. 2y = 30 because corresponding angles. ergo, w = 50

x = 100

y = 15

z = 50
