Can someone please help me?

Answer:

Step-by-step explanation:

f(x) = 4x² + 7

To find f(-3) substitute the value of x that's - 3 into f (x) that's replace every x in f (x) by - 3

We have

f(-3) = 4(-3)² + 7

= 4(9) + 7

= 36 + 7

We have the final answer as

Answer:

y = 35    x = 39

Step-by-step explanation:

Let large no = x and small no = y

According to the question,

x = 4 + y ------ (1)

x + y = 74 -------- (2)

Substituting (1) in (2)

( 4 + y ) + y = 74

4 + 2y= 74

2y = 74 -4

y = 70 / 2 = 35

x = 4 + y

  = 4 + ( 35 )

   =  39

Answer:

22/15 in fraction 1 7/15

Step-by-step explanation:

Answer:

___________

Exact Form:

22 / 15

Decimal Form:

1.46 continuous

Mixed Number Form:

1 7/15

To write 9/5 as a fraction with a common denominator, multiply by 3/3

9/5 x 3/3 - 1/3

To write −1/3  as a fraction with a common denominator, multiply by 5/5.

9/5 x 3/3−1/3 x 5/5

Write each expression with a common denominator of 15, by multiplying each by a factor of 1

Multiply 9/5 and 3/3

9 x 3/5 x 3 - 1/3 x 5/5

Multiply 5 by 3

9 x 3/15 − 1/3 x 5/5

Multiply 1/3 and 5/5

9 x 3/15 − 5/3 x 5

Multiply 3 by 5

9 x 3/15 − 5/15

Then combine the numerator over the common denominator

9 x 3 - 5 / 15

then simplify the numerator

mutiply 9 by 3

27 - 5/15

subtract 5 from 27

22/15

Answer:

The code is 571113

Step-by-step explanation:

The problem requires that we find the prime factors of 5005

1. 5005 is a multiple of 5 since it ends with a number 5

5 is one of the numbers

Dividing 5005/5 = 1001

the next prime number after 5 is 7

so 1001/7= 143

7 is one of the numbers

the next prime number after 7 is 11

so 143/11= 13

13 is one of the numbers

In all the prime factorization of 5005 is found as follows

5,7 11,13

Combining these numbers gives the 6 digit code

571113

Answer: p²-3

Step-by-step explanation:

3 less than the square of a number p=p²-3

When coming across [a less than b], this means b-a.

If you are pretty confused with this variable expression, I will provide to you with some numerical examples.

This pattern will also apply for p

Step-by-step explanation:

Answer:

[tex]LS = 63[/tex]

Step-by-step explanation:

Given

[tex]LS = 14x - 21[/tex]

[tex]LH = 15[/tex]

[tex]HS = 8x[/tex]

Required

Determine the length of LS

Since H is between L and S, then

[tex]LS = LH + HS[/tex]

Substitute 14x - 21 for LS, 15 for LH and 8x for HS

[tex]14x - 21 = 15 + 8x[/tex]

Collect Like Terms

[tex]14x - 8x = 21 + 15[/tex]

[tex]6x = 36[/tex]

Divide both sides by 6

[tex]x = 6[/tex]

Substitute 6 for x in [tex]LS = 14x - 21[/tex]

[tex]LS = 14(6) - 21[/tex]

[tex]LS = 84 - 21[/tex]

[tex]LS = 63[/tex]

Hence, the length of LS is 63 units

Answer:

100000000000 times

Step-by-step explanation:

Given

Diameter of Dish = 0.00001 km

Diameter of Bacterium = 10⁻¹⁶ km

Required

Determine the number of times the diameter of dish is bigger than that of the bacterium

To solve this, we simply divide the diameter of dish by the diameter of the bacterium as follows

[tex]Ratio = \frac{Dish}{Bacterium}[/tex]

[tex]Ratio = \frac{0.00001}{10^{-16}}[/tex]

[tex]Ratio = 100000000000[/tex]

Hence, the diameter of the dish is 100000000000 times larger than the diameter of the bacterium

Answer:

9

Step-by-step explanation:

Answer:

[tex]3i\sqrt{2}[/tex]

Step-by-step explanation:

If we have the expression [tex]\sqrt{-18}[/tex], we can divide -18 by 2.

[tex]\sqrt{2\cdot-9}[/tex]

The square root of 9 is 3, and since we’re finding the square root of a negative number, we append the “i” to the term: so 3i.

This goes outside the root, making the expression [tex]3i\sqrt{2}[/tex].

Answer:

            About 20

           {19 exactly}

Step-by-step explanation:

Evaluate means find approximate value without exact calculation (usually done with great numbers or with fractions)

-8 is approximately -(2+5) so the sum is about 0

34-14 = 30-10 = 20

20 + 0 = 0

The exact calculation would be:

34 -8 - 14 + 2 + 5 = 34 - 14 - 8 + 7 = 20 - 1 = 19

Answer: (-7, 7)

Step-by-step explanation:

Answer:

[tex]\mathrm{Solution\:} = (- 7,7) = \mathrm{Last\:}\mathrm{Option\:}[/tex]

Step-by-step explanation:

In my point of view the easiest approach to solving this problem would be by determining the distance between the given points (the midpoint and the other given point) --- (1) and then going through all the answer choices and matching their distance to the midpoint --- (2). This may seem like a hard approach, but you can eliminate many of the answer choices.

The answer is the last choice, so let's prove it.

[tex]\mathrm{Distance\:between\:}\left(1,\:5\right)\mathrm{\:and\:}\left(9,\:3\right) = \sqrt{\left(9-1\right)^2+\left(3-5\right)^2} = 2\sqrt{17}[/tex]

[tex]\mathrm{Distance\:between\:}\left(1,\:5\right)\mathrm{\:and\:}\left(-7,\:7\right)=\sqrt{\left(-7-1\right)^2+\left(7-5\right)^2}=2\sqrt{17}[/tex]

[tex]2\sqrt{17} = 2\sqrt{17}[/tex]

As the distance between points (1,5) and (9,3) respectively (1,5) and (- 7,7) is the same, we proved that our answer is the last choice.
