Answer:
It is irrational and equal to 5 times the square root of 2.
Step-by-step explanation:
The statement that is true about the expression:
( √(32) ) + √2
( √(16 * 2) ) + √2
( √(4²) *√2 ) + √2
( 4 *√2 ) + √2
( √2+√2+√2+√2 ) + √2
...and this is ( 4 ) + 1 times √2
The answer is 5 times √2
So the expression is irrational and equal to 5 times the square root of 2.
Answer:
B
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here the vertex = (- 2, - 3 ) , then
y = a(x - (- 2))² - 3 , that is
y = a(x + 2)² - 3
To find a, substitute any point on the graph into the equation
Using the coordinates of the y- intercept (0, 5 )
5 = a(0 + 2)² - 3 ( add 3 to both sides )
8 = a(2)² = 4a ( divide both sides by 4 )
2 = a
y = 2(x + 2)² - 3 → B

Responder:
500
Explicação passo a passo:
O número a subtrair de 12.750 em outro para obter 12.250
Deixe o número = x
Isso é ; se x for subtraído de 12750; nós obtemos 12250
12750 - x = 12.250
Subtraia 12750 de ambos os lados
12750 - x - 12750 = 12.250 - 12750
-x = - 500
x = 500
Answer:
4
Step-by-step explanation:
Given data
Number of student= 3
Total amount= 12000
Ratio= 6:5:x
Combined ratio= 6+5+x= 11+x
Applying the part to all method
if student number 2 got sh 4000
then
5/11+x= 4000/12000
5/11+x= 1/3
cross multiply
11+x= 15
x= 15-11
x= 4
Hence the value of x is 4
