Answer:

D

Step-by-step explanation:

The statement which must be true about D, the discriminant of function h is D =0 hence, option (D) must be correct.

When working with quadratic equations, the discriminant is commonly calculated to investigate the kind of roots. Even though it is difficult to ascertain a discriminant for any polynomial, there exist methods for collecting the discriminant of cubic and quadratic equations that reduce our approach.

The discriminant function gives us an idea about the nature of the solution whether it is real or not if real then how much will be the solution?

If D > 0 then there will be 2 real solutions.

If D = 0 then there will be 1 real solution.

If D < 0 then there will be 2 imaginary solutions.

Given that function, h has an interception it means there will be a real solution. Hence, D = 0 will be the correct answer.

Answer:

-25

Step-by-step explanation:

The following are x-values (inputs) and their y-values (outputs) that are one value apart:

(Input, output)

✅(-2, 20) and (-1, -5)

Difference between their outputs = -5 - 20 = -25

✅(-1, -5) and (0, -30)

Difference between their outputs = -30 -(-5) = -25

✅(0, -30) and (1, -55)

Difference between their outputs = -55 -(-30) = -25

✅(1, -55) and (2, -80)

Difference between their outputs = -80 -(-55) = -25

As we can see the difference of outputs for any two inputs that are one value apart = -25

Answer:  8 x 7 = 56   7 x 8 = 56     56/8=7      56/7=8

Step-by-step explanation: the way that you do it you will the same numbers

Step-by-step explanation: 8: 1,8, 2,4,4,2 8,1

                                              7: 1,7,

                                              56: 1,56,7,8,8,7

Step-by-step explanation:

on the first one you can actually draw a number line and show a positive side and the negative side so you can actually decide the spacing like we can say the scale like one centimetre represents 4/4 like what I did.

On the second one you can actually choose to write any kind of situation that you prefer for instance, i chose Point Marks that you're given in an exam. If you didn't give the assignment on time then you get -5 then you gave the assignment on time you get +5 marks then sometimes you get zero marks like you fail the assignment you get zero then the zero always represents the neutral number like a marker that differentiates the integers from negative to positive and vice versa.

Answer:   Width of box is not taken up by pencils =  [tex]2\dfrac58\text{ inches}[/tex]

Width of each pencil [tex]=\dfrac38\text{ inches}[/tex]

Step-by-step explanation:

Given: Width of pencil box = [tex]5\dfrac14\text{ inches}=\dfrac{21}{4}\text{ inches}[/tex]

Width of seven pencils = [tex]2\dfrac58\text{ inches}=\dfrac{16+5}{8}\text{ inches}=\dfrac{21}{8}\text{ inches}[/tex]

Width of box is not taken up by pencils =  Width of pencil box  - Width of seven pencils

[tex]\left \{ {{y=2} \atop {x=2}} \right. \dfrac{21}{4}-\dfrac{21}{8}\\\\=\dfrac{21\times2-21}{8}\\\\=\dfrac{21}{8}\text{ inches}=2\dfrac58\text{ inches}[/tex]

Width of box is not taken up by pencils =  [tex]2\dfrac58\text{ inches}[/tex]

Width of each pencil = (Width of seven pencils ) ÷ 7

[tex]=\dfrac{21}{8}\div7\\\\=\dfrac{21}{8}\times\dfrac17\\\\=\dfrac38\text{ inches}[/tex]

Width of each pencil [tex]=\dfrac38\text{ inches}[/tex]

Answer:

y=2

Step-by-step explanation:

[tex]22-7y=8[/tex]

Subtract 22 from both sides

[tex]-7y= -14[/tex]

Divide by -7 on both sides

[tex]y=2[/tex]

Answer:

The required dimensions that can be scaled versions of given rectangle are:

Height = 12, Width=18

Height = 30, Width=45

Step-by-step explanation:

Given that height to width ratio is:

3: 4.5

Any ratio equivalent to this or which simplifies to this ratio will be the scaled version of the given rectangle.

Remembering that both sides of the ratio can be multiplied with a number.

So,

The scaled versions can be:

[tex]4(3):4(4.5)\\12:18\\AND\\10(3): 10(4.5)\\30:45[/tex]

The required dimensions that can be scaled versions of given rectangle are:

Height = 12, Width=18

Height = 30, Width=45

Answer:

241,920 different ways

Step-by-step explanation:

We have 6 vowels, but A repeats twice and I repeats three times, so the number of ways in which each can either start or end the word:

³P₂ = 3! / (3 - 2)! = 6 / 1 = 6 ways

You can start words with A, E or I, or end the words with A, E, or I.

the remaining 8 consonants can be arranged in 8! ways = 40,320 ways

total number of ways that the letters can be arranged = 6 x 40,320 = 241,920 different ways

The total number of ways the researcher arrange the word CALLITRICHIDAE that start or end with vowels is 6 ways and this can be determined by using the given data.

Given :

Word  --  CALLITRICHIDAE

The following steps can be used in order to determine the total number of ways the researcher arrange the word CALLITRICHIDAE:

Step 1 - First, calculate the total number of vowels in the given word CALLITRICHIDAE.

Total vowels = 6

Step 2 - Now, determine the total number of times a letter repeat in the word CALLITRICHIDAE.

So, the letter A appears 2 times and letter I appears 3 times in the word CALLITRICHIDAE.

Step 3 - Now, evaluate the total number of ways the word CALLITRICHIDAE is arranged:

[tex]\rm Total \;Number\; of\; Ways=\; ^3P_2 = \dfrac{3!}{(3-2)!}=6[/tex]
