Answer: For instance, during hibernation, the gopher’s body temperature will drop from its normal 37 degrees Celsius to almost 0 degrees Celsius.

Answer:

[tex]a-(-b)>a[/tex]

Step-by-step explanation:

ok so lets round  =-3 and b=2

ok so now lets solve -3-(-2)=-3+2

remember when you subtract a negative it is just like adding

so -3+2=-1 and -1 is greater than -3

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

To reflect a function over the x-axis, we multiply the function by -1. So, if f(x) is the original function, then -f(x) is the function across the x-axis.

To reflect a function over the y-axis, we multiply the inside of the function by -1. So, if f(x) is the original function, then f(-x) is the function across the x-axis.

We have:

[tex]f(x)=(x-1)^2+1[/tex]

Then:

[tex]f(-x)=(-x-1)^2+1=f ^\prime(x)[/tex]

We can see that the choice that resembles this is A. If we let:

[tex]f(-4x)=(-4x-1)^2+1[/tex]

This is a reflection over the y-axis followed by a horizontal compression by a factor of 4.

Hence, our answer is A.

=====================================================

Explanation:

Since the range of [tex]y = \sqrt{x}[/tex] is [tex]y \ge 0[/tex], this means that [tex]\sqrt{53+20\sqrt{7}}[/tex] cannot be negative.

-----------------------------------

Let's set the given nested radical expression equal to the form a+b*sqrt(c), and then square both sides to see what happens

[tex]\sqrt{53+20\sqrt{7}} = a+b\sqrt{c}\\\\\left(\sqrt{53+20\sqrt{7}}\right)^2 = \left(a+b\sqrt{c}\right)^2\\\\53+20\sqrt{7} = a^2+2ab\sqrt{c}+b^2c\\\\53+20\sqrt{7} = (a^2+b^2c)+2ab\sqrt{c}\\\\[/tex]

Equating the corresponding parts shows that

[tex]53=a^2+b^2c \text{ and } 20\sqrt{7} = 2ab\sqrt{c}\\\\[/tex]

Therefore c = 7 must be the case to allow the radicands to match up.

-----------------------------------

Since c = 7, we can update the first equation like so

[tex]53=a^2+b^2c\\\\53=a^2+b^2*7\\\\53=a^2+7b^2\\\\[/tex]

We'll come back to this later.

-----------------------------------

Focus on [tex]20 = 2ab\sqrt{7}[/tex]

Note how 20 and 2ab are coefficients outside the root. So 20 = 2ab leads to ab = 10.

Here are all the ways to multiply to 10 where a,b are integers

So we could have these possibilities.

If you try all of those a,b combinations with [tex]53 = a^2 + 7b^2[/tex], then you should find that a = 5 and b = 2 works. I'm skipping a bunch of steps here. All you basically do is plug and chug.

Due to symmetry, we could have a = -5 and b = -2 as another solution to [tex]53 = a^2 + 7b^2[/tex]. However, if a < 0 and b < 0, then [tex]a+b\sqrt{c}[/tex] would be negative which contradicts the fact that [tex]\sqrt{53+20\sqrt{7}}[/tex] is positive. So we'll ignore any case where a,b are negative.

Therefore, the only combination that works is a = 5 and b = 2

-----------------------------------

Overall, we found that

And therefore,

[tex]\sqrt{53+20\sqrt{7}} = a+b\sqrt{c}\\\\\sqrt{53+20\sqrt{7}} = 5+2\sqrt{7}\\\\[/tex]

You can confirm this with your calculator by taking advantage of the idea "If x = y, then x-y = 0". In other words, if you subtract the left and right sides, you should get 0 as a result (the order of subtraction doesn't matter in this case). Don't forget to use parenthesis correctly, or you may not get 0. It might help to think of it as the form (x) - (y) = 0.

After we confirmed we have the correct a,b,c values, we simply add them up to get a+b+c = 5+2+7 = 14.

Answer:

slope is 4, so m=4

Step-by-step explanation:

y=4x+0

You do not need to include the 0, but that would be in the place of b.

If you need a coordinate for x and y, use (4,1)

Answer:

w+ (9+3)

Step-by-step explanation:

pretty simple if I remember how to use that property

Answer:

The equivalent expression for the given expression (w+9)+3 using associative property is w + 12

Solution:

Given that, expression is ( w + 9 ) + 3

We have to find how do we can use the associative property to write an expression equivalent to ( w + 9 ) + 3

The associative property states that you can add or multiply regardless of how the numbers are grouped

By above definition, we get

(a + b) + c = a + (b + c)

So, now let us apply the above property to the given expression,

Then, ( w + 9 ) + 3 = w + ( 9 + 3 ) = w + 12

Hence, the equivalent expression for the given expression is w + 12

Answer:

Third option

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

Where "m" is the slope of the line and "b" is the y-intercept.

Given the function f(x):

Since , you can rewrite it:

You can identify that:

Therefore, you can determine that the y-intercept of the given function is:

Observe that this matches with the third option.
