If a temperature in degrees Celsius this is given as C finding the sum of 1.8 timesC and 33 gives the temperature in degrees Fah

aleksley [76]

Alright well first off, converting Celsius to Fahrenheit is 1.8c+32. converting Fahrenheit to Celsius is 5(f-32)/9.
the temperature in Fahrenheit is given by °f.
40°c is equal to 104°f.

In which direction does the graph of the function shown below open?

sp2606 [1]

Answer:

D. Up

Step-by-step explanation:

When a parabola has the form $y=ax^2+bx+c$ , It is vertical (opens up or down).

Because the variable "x" is squared.

If "a" is positive, then the parabola opens up, but if it is negative, then the parabola opens down.

In this case you have the quadratic function:

$f(x) = 2x^2+5x-4$

Which can be rewritten as:

$y = 2x^2+5x-4$

Therefore, it is vertical, because it has the form: $y=ax^2+bx+c$

You can observe that the value of "a" is:

$a=2$

Then, since "a" is positive, the parabola opens up.

Define the value of the expression 3^2 x 3^{-5}

Tanya [424]

Answer:

Between 0 and 1

Step-by-step explanation:

The given expresion is

${3}^{2} \times {3}^{ - 5}$

Recall that:

${a}^{m} \times {a}^{n} = {a}^{m + n}$

We apply this property of exponents to get;

${3}^{2} \times {3}^{ - 5} = {3}^{2 + - 5} = {3}^{ - 3}$

We rewrite to obtain a positive index as:

${3}^{2} \times {3}^{ - 5} = \frac{1}{ {3}^{3} } = \frac{1}{27}$

Therefore the value of the expression is between 0 and 1.

Find the distance :

faltersainse [42]

1. You would do 45 × 3 = 135 miles
2. 630 ÷ 2 = 315. 630 + 315 = 945 miles
3. 54 × 11 = 594 miles

1. Time is distance ÷ speed, so 4760 ÷ 560 = 8 1/2hours
2. 27 ÷ 54 = 0.5 hours, or 30 minutes
3. 1748 ÷ 437 = 4 hours

I hope this helps!
