Which of the following depicts a graph of a polynomial with a negative leading coefficient?

Answer:

3 with the exponent of four.

Step-by-step explanation:

You would count the number of of three's. Since there are four three's, then you would write the 4 right by the three on the top right hand corner.

The exponential expression is [tex]3^4[/tex].

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

3 x 3 x 3 x 3

The form to write an exponential expression.

= [tex]Base^{Exponents}[/tex]

Now,

There are four 3's and we can write it as an exponent form where the base is 3 and the exponent is 4.

So,

= [tex]3^4[/tex]

Thus,

The exponential expression is [tex]3^4[/tex].

During a science experiment, Daniel noted the starting temperature of a -4°F. At the end of the experiment, the change in temperature was -5°F. What was the final temperature?

A.-1 B.1 C.9 D.-9

Answer:

D.) - 9

Step-by-step explanation:

Given the following :

Temperature at the start of experiment = - 4°F

At the end of experiment, change in temperature = - 5°F

This means between the temperature at the start of the experiment was - 4°F and during the cause of the experiment, there was a change in temperature of - 5°F.

Hence, the final temperature is the sum of the initial temperature and and the temperature change recorded.

Initial temperature + temperature change

-4°F + (-5°F)

- 4°F - 5°F = - 9°F

Hence, final temperature = - 9°F

Answer:

The answer is 9

Given the following :

Temperature at the start of experiment = - 4°F

At the end of experiment, change in temperature = - 5°F

This means between the temperature at the start of the experiment was - 4°F and during the cause of the experiment, there was a change in temperature of - 5°F.

Hence, the final temperature is the sum of the initial temperature and and the temperature change recorded.

Initial temperature + temperature change

-4°F + (-5°F)

- 4°F - 5°F = - 9°F

Hence, final temperature = - 9°F

$3.07

Step-by-step explanation:

15 - ((2*2.65) + (2*1.79) + (1*3.05))

= 15 - (5.3 + 3.58 + 3.05)

= 15 - 11.93

= 3.07

Answer:

$3.07

Step-by-step explanation:

Ms. Gantt has a $15 gift card to Starbucks.

She buys 2 muffins for $2.65 each, = 2 × 2.65 = $5.3

2 hot chocolates for $1.79 each, = 2 × 1.79 = $3.58

and a juice for $3.05. = 1 × 3.05 = $3.05

Now,

$15 - $5.3 - $3.58 - $3.05 = $3.07

Thus, $3.07 remains on her gift card

Answer:

x = 24

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

a = a leg

b = another leg

c = hypotenuse

Step 1: Plug in known variables

x² + 10² = 26²

Step 2: Evaluate

x² + 100 = 676

Step 3: Isolate x term

x² = 576

Step 4: Isolate x

√x² = √576

x = 24

Answer:

[tex]x=24[/tex]

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean Theorem.

The Pythagorean Theorem is:

[tex]a^2+b^2=c^2[/tex]

The hypotenuse is c, and the legs are a and b.

Plug in 26 for c since 26 is the hypotenuse, and let 10 for a and x be b. Therefore:

[tex]x^2+10^2=26^2[/tex]

Square:

[tex]x^2+100=676[/tex]

Subtract 100 from both sides:

[tex]x^2=576[/tex]

Take the square root of both sides:

[tex]\sqrt{x^2}=\sqrt{576}\\x=\sqrt{576}=24[/tex]

The answer is 24.

Answer:

If half the students scored 42 and some scored 53, the median must be (53 + 42)/2 = 47.5.

If the other half all scored 53, the mean would be the same, but the few 78s is going to raise the mean.

The mode is 42.

i hope it helps you

The mean is greater than the median. Then the correct option is B.

Statistics is the study of collection, analysis, interpretation, and presentation of data or to discipline to collect, and summarise the data.

In a mathematics class, half of the students scored 42 on an achievement test.

With the exception of a few students who scored 78, the remaining students scored 53.

We know that if the half of data is the same and the remaining data is greater than that data.

Then the mean is greater than the median.

Then the correct option is B.

Answer:  B and C.

Step-by-step explanation:

A function will have an inverse, only and only if every value of y can be linked to only one value x.

A) Here we have an absolute value:

We know that for example:

I5I = 5 and I-5I = 5.

Then an absolute value function can not have an inverse function.

B) one way of having a function that is invertible or not, is see if the function is increasing or decreasing.

If a function is, for example, increasing, then as the value of x increases, also does the value of y.

Then we will never see that a single value of y is related to two or more different values of x.

Then an exponential function, which is an increasing function, will have an inverse that is also a function.

C) A cubic function that has a root in (0,0)

The cubic function that has only one root at x = 0 is the function:

f(x) = a*x^3 + b*x

where a and b are real numbers of the same sign.

Now, we can see at the first derivate of f(x) to see if it is strictly increasing or strictly decreasing.

f'(x) = 3*a*x^2 + b

Ok, as x^2 is always positive, we can know that the sign of f'(x) will always be the same, so this function is strictly increasing or strictly decreasing (it depends on the signs of a and b).

Then this function has an inverse that is also a function.

Exponents multiply a base number by itself continuously

Exponents create repeated multiplication, where the base number will be continuously multiplied by itself.

The number of times it will be multiplied depends on the exponent.

For example, 2³ will be the number 2 multiplied by itself 3 times.

Answer:

If you mean only one rational solution, the answer is

[tex]k_1 = 8, k_2 = -8[/tex]

If you mean at least 1 rational solution, the answer is

[tex]k\in (-\infty, -8]\cup[8, \infty)[/tex]

Step-by-step explanation:

[tex]4x^2 + kx + 4 = 0[/tex]

Let's calculate the discriminant.

[tex]\Delta = b^2 - 4ac[/tex]

[tex]\Delta = k^2 -4 \cdot 4 \cdot 4[/tex]

[tex]\Delta = k^2 -64[/tex]

Now, remember that:

[tex]\text{If } \Delta > 0 : \text{2 Real solutions}[/tex]

[tex]\text{If } \Delta = 0 : \text{1 Real solution}[/tex]

[tex]\text{If } \Delta < 0 : \text{No Real solution}[/tex]

Therefore, I will just consider the first two cases.

[tex]k^2 - 64 > 0[/tex]

and

[tex]k^2 -64 = 0[/tex]

[tex]\boxed{\text{For } k^2 - 64 > 0}[/tex]

[tex]k^2 > 64 \Longleftrightarrow k>\pm\sqrt{64} \Longleftrightarrow k\in (-\infty, -8)\cup(8, \infty)[/tex]

[tex]\boxed{\text{For } k^2 - 64 = 0}[/tex]

[tex]k^2 = 64 \Longleftrightarrow k=\pm\sqrt{64} \implies k_1 = 8, k_2 = -8[/tex]

Answer:

[tex]\frac{x^2}{25}+\frac{y^2}{16}=1[/tex]

Step-by-step explanation:

We know that the foci lies on the major axis, so it should lie on the x - axis. Additionally the center is the midpoint of the line joining the foci, at (0,0).

Now remember we have our foci at the point (0, ± 3). Our major axis length is 10, so if covers 5 units on either side of the x - axis. Therefore, c = 3, and a = 5. But remember that c is not part of an ellipse equation. Take a look at the formula below,

(x - h)^2 / a^2 + (y - k)^2 / b^2 = 1

However we can solve for " b " instead, using c. Take a look at another major formula below,

c^2 = a^2 - b^2,

(3)^2 = (5)^2 - b^2,

9 = 25 - b^2,

- b^2 = 16,

b = 4 = - 4

Whether b = - 4 or b = 4, or equation will be the same.

(x - 0)^2 / (5)^2 + (y - 0)^2 / (4 or - 4)^2 = 1,

x^2 / 25 + y^2 / 16 = 1

Our solution is hence option number 1 : [tex]\frac{x^2}{25}+\frac{y^2}{16}=1[/tex]
