It takes Sara 5 1/2hours to drive to her aunt's
house. She has already driven 3 1/2 hours.
How much longer does Sara have left to
drive?

Answers

Answer:

2 hours

Step-by-step explanation:

To solve this question, we can convert the fraction into decimal form momentarily, so that 5 1/2 is now 5.5, and 3 1/2 is now 3.5. We know that Sara has already driven 3.5 hours, and it takes 5.5 to get to her aunts house. To dins how much longer Sara has left to drive, simply subtract the total amount of hours by the hours already completed:

5.5 - 3.5 = 2.0

Meaning, Sara has 2 hours left to drive

When the swimmers first arrived at the pool, the temperature of the water was only 72.5 degrees. By the time the first race started, the temperature had gone up 5.6 degrees. What was the temperature of the water when the first race started?

Answers

Answer:

The temperature of the water when the first race started was 78.1 degrees

Step-by-step explanation:

Addition

The temperature of the water of a pool was 72.5 degrees when the swimmers first arrived.

By the time when the first race started, the temperature had increased by 5.6 degrees.

To find the temperature at that very moment we have to add 72.5 degrees + 5.6 degrees = 78.1 degrees

The temperature of the water when the first race started was 78.1 degrees

[tex]\boxed{\textsf{ The roots of the quadratic equation is \textbf{ (-4) and 3 }.}}[/tex]

Step-by-step explanation:

A quadratic equation is given to us . Here we aren't given what to do with it. So , lets find out the roots of the equation . The given quadratic equation is :-

[tex]\sf\implies 4x^2+x-3 =0[/tex]

Now with respect to Standard form ax²+bx + c . The roots of the equation can be find out by the quadratic formula also known as " Shreedharyacharya's Formula " .

Quadratic Formula :-

[tex]\boxed{\boxed{\sf x =\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}}}[/tex]

Now with respect to Standard Form we have ,

• a = 4 •b = 1 •c = (-3)

Put on the respective values :-

[tex]\sf\implies x = \dfrac{-b\pm \sqrt{b^2-4ac}}{2a} \\\\\sf\implies x =\dfrac{-1\pm\sqrt{1^2-4(1)(-3)}}{2(1)}\\\\\sf\implies x =\dfrac{-1\pm \sqrt{1+48}}{2}\\\\\sf\implies x =\dfrac{-1\pm \sqrt{49}}{2}\\\\\sf\implies x = \dfrac{-1\pm 7 }{2}\\\\\sf\implies x =\dfrac{-1-7}{2},\dfrac{-1+7}{2}\\\\\sf\implies x =\dfrac{-8}{2},\dfrac{6}{2}\\\\\sf\implies \boxed{\pink{\sf x = (-4) , 3 }}[/tex]

Is 23, 11, 25, 19 a composite number?

Answers

Answer:

23 is a prime number. 11 is a prime number. 25 is a composite number. and 19 is a prime number.

Step-by-step explanation:

Hi there!

23 is a prime number because it has only two factors - 1 and itself.

Remember, a factor is a number that a number can be evenly divided by. So 3 is not a factor of 23.

11 is prime as well.

25 is a composite number because it's last digit is 5. If a number's last digit is 5, then it's divisible by 5. Therefore, it's composite.

19 is a prime number.

at what value of x does the graph of the following function f(x) have a vertical asymptote? f(x)=1/x-6

Answers

Answer:

x = 6

Step-by-step explanation:

A vertical asymptote is a vertical line going through the x-axis at an x-value that x is not actually allowed to have.

In this case, we have a 'rational' function, meaning there is a 'ratio' or fraction involving the variable x.

With these 'rational' or fractional expressions, we always have to watch out to make sure we never have a denominator equal to zero, because division by zero is not defined. It is meaningless.

The denominator x-6 will equal zero if x is 6, so x cannot actually ever be 6.

That is where the vertical asymptoe goes: a vertical line with the equation x = 6.

The value of x is 6.

The following information should be considered:

A vertical asymptote is a vertical line that gone via the x-axis at an x-value where x is not actually allowed to have. In the given case,  it have a rational function, that means there is a ratio or fraction involving the variable x. The denominator x-6 will equal zero in the case when x is 6, so x cannot actually ever be 6. So,  where the vertical asymptoe goes: a vertical line with the equation x = 6.

A proportional function has the equation

y = kx, where k is the constant of proportionality and also the slope of the line.

Answer: y = 3x

The equation that represents the line whose slope of proportional relationship is 3 is; y = 3x.

The slope of the proportional relationship as given is 3.

In essence, slope, m = 3.

However, the equation of the line which represents a proportional relationship usually takes the form; y = Mx.

Since, slope, m = 3.

The equation of the line is; y = 3x.
