Answer:  (-0.4, 6.8)

The graph is attached

Step-by-step explanation:

We can find the axis of symmetry using the formula x = -b/2a

x = - -4/2(-5)

x = 4/-10

x = 0.04

Substitute for x and calculate y

y = \left(0.4^{2}\right)\left(-5\right)-4\left(-0.4\right)\ +6

y = 6.8

Answer the following.
vodka [1.7K]

Answer:

(a) 51,100 kilometers.

(b) y = 7.68 * 10^{-6} meters

Step-by-step explanation:

(a) When converting from scientific notation to standard notation, split the equation.

When solving 5.11 * 10^{4}, begin by calculating 10^{4}.

10^{4} = 10,000

Multiply this by '5.11', resulting in:

5.11 × 10000 = 51,100 kilometers.

(b) When converting from standard form to scientific notation, count the number of zeros until the first non-zero digit. Therefore:

In 0.00000768, the '7' is placed 6 digits from the decimal. Recall that for decimals, the exponent is negative. Therefore in scientific notation, this equals: y = 7.68 * 10^{-6}

Penny, Amjit and James share some money in the ratio 3 : 6 : 4
ki77a [65]

Answer:

$42

Step-by-step explanation:

Let the amounts received by Penny, Amjit and James be 3x, 6x and 4x respectively.

According to the given information:

Amount received by Amjit = Amount received by James + 28

So,

6x = 4x + 28

6x - 4x = 28

2x = 28

x = 28/2

x = 14

Amount of money received by Penny = 3x = 3*14 = $42
