If 4 is added to 3 times a number “a” the result is 16. What is the number?

[tex]\\ \sf\longmapsto \dfrac{dy}{dt}[/tex]

[tex]\\ \sf\longmapsto \dfrac{d}{dt}(3x+5)^3[/tex]

[tex]\\ \sf\longmapsto \{3(3x+5)\}^2[/tex]

[tex]\\ \sf\longmapsto (9x+15)^2[/tex]

[tex]\\ \sf\longmapsto 9x^2+2(9x)(15)+(15)^2[/tex]

[tex]\\ \sf\longmapsto 81x^2+270x+225[/tex]

Step-by-step explanation:

[tex]y=(3x+5)^3\\\\\dfrac{dy}{dx}=\dfrac{d}{dx}(3x+5)^3\\\\\dfrac{dy}{dx}=3(3x+5)^2×\dfrac{d}{dx}(3x+5)\\\\\dfrac{dy}{dx}=3(3x+5)^2×\dfrac{d}{dx}3x+\dfrac{d}{dx}5\\\\\dfrac{dy}{dx}=3(3x+5)^2×3+0\\\\\dfrac{dy}{dx}=9(3x+5)^2\\\\\dfrac{dy}{dx}=9(9x^2+25+30x)\\\\\dfrac{dy}{dx}=81x^2+270x+225[/tex]

Answer:

Answer:

Its correct good job

Step-by-step explanation:

a) 3.2a, -4 1/3a, -a

b) -2.133a+6

Answer:

I believe it is answer b.

Step-by-step explanation:

You multiply 4x and - 7 by 1/5 which gives you 4/5x and 1 2/5. You add 4/5x and 2/5x as they are like terms and get 1 1/5x. The equation then becomes 1 1/5 - 1 2/5

Answer:

y=6x+10

Step-by-step explanation:

y=6x

y-5=6(x-1)

y-5=6x+5

+5 +5

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

y=6x+10

Solution :-

We need to find out the sum of 50 terms of the given sequence . After splitting the given sequence ,

[tex]\implies S_1 = \dfrac{1}{2},\dfrac{1}{4},\dfrac{1}{8}[/tex] .

We can see that this is in Geometric Progression where 1/2 is the common ratio . Calculating the sum of 25 terms , we have ,

[tex]\implies S_1 = a\dfrac{1-r^n}{1-r} \\\\\implies S_1 = \dfrac{1}{2}\left[ \dfrac{1-\bigg(\dfrac{1}{2}\bigg)^{25}}{1-\dfrac{1}{2}}\right] [/tex]

Notice the term [tex]\dfrac{1}{2^{25}}[/tex] will be too small , so we can neglect it and take its approximation as 0 .

[tex]\implies S_1\approx \cancel{ \dfrac{1}{2} } \left[ \dfrac{1-0}{\cancel{\dfrac{1}{2} }}\right] [/tex]

[tex]\\\implies \boxed{ S_1 \approx 1 }[/tex]

[tex]\rule{200}2[/tex]

Now the second sequence is in Arithmetic Progression , with common difference = 3 .

[tex]\implies S_2=\dfrac{n}{2}[2a + (n-1)d] [/tex]

Substitute ,

[tex]\implies S_2=\dfrac{25}{2}[2(4) + (25-1)3] =\boxed{ 908} [/tex]

Hence sum = 908 + 1 = 909

Answer:

200

Step-by-step explanation:

You can simply just graph it and see where the points intersect, or you can do it algebraically.

0.45x+29.99=0.40x+39.99 subtract 29.99 both sides

0.45x=0.40x+10.00 subtract .40x both sides

0.05x=10.00 divide both sides by 0.05

x=200

Hi There!

9f+5=77

Make sure all numbers are on the right side of the equation.

9f=77-5

9f=72

Now divide both sides by 9 to isolate f:

f=8

Answer:

$2.57

Step-by-step explanation:

Create an equation.

7x + 3 = 21

Subtract 3 from both sides of the equation.

7x = 18

Divide 7 from both sides to find x.

18/7 = x,

x = 2.57

The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

Given that, a company charges a delivery fee of $50 to deliver plotting soil and each cubic yard of plotting soil costs $50.

In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".

Let the total cost be y and the number of cubic yards be x.

Now, the equation to represent the given situation is y = 50+50x

By substituting x = 0, 1, 2, 3, 4, 5,....we get

y = 50+50(0) = 50

y = 50+50(1) = 100

y = 50+50(2) = 150

y = 50+50(3) = 200

y = 50+50(4) = 250

So, the coordinates to plot the graph are (0, 50), (1, 100), (2, 150), (3, 200) and (4, 250) and so on.

The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

The derivative at x = 3 does not exist.

To see why, recall the definition of absolute value:

[tex]|x| = \begin{cases}x&\text{if }x\ge0\\-x&\text{if }x<0\end{cases}[/tex]

If x - 3 ≥ 0, then

2 + |x - 3| = 2 + (x - 3) = x - 1

and the derivative of this piece is 1 for all x > 3.

If x - 3 < 0, then

2 + |x - 3| = 2 - (x - 3) = 5 - x

and its derivative is -1 for all x < 3.

The derivatives to either side of x = 3 are not the same, so f '(x) is not continuous and indeed does not take on any value at this point.

Answer:

The slope-intercept form is y=mx+b y = m x + b

Step-by-step explanation:

where m m is the slope and b b is the y-intercept. Subtract 2x 2 x from both sides of the equation. Divide each term by 3 3 and simplify. Divide each term in 3y=24−2x 3 y = 24 - 2 x by 3 3 .

Answer:

1.Geometric proofs can be written in one of two ways: two columns, or a paragraph. A paragraph proof is only a two-column proof written in sentences. ... A two-column geometric proof consists of a list of statements, and the reasons that we know those statements are true.

2.ray AB is not same as ray BA as ray AB has the starting point A and ray BA has B as the starting point.

3.∠ABC  refers to an angle, a geometric object.

m∠ABC  refers to the measure of  ∠ABC  which is a real number describing how “open” the angle is.

Answer:

f(x) = x³ + 19x² + x + 19

Step-by-step explanation:

Zeros: -19 , -i, complex conjugate root: +i

Function: (x+19)(x+i)(x-i) = 0

(x + 19) (x² - i²) = (x + 19) ( x² + 1) = x³ + 19x² + x + 19

check: when x = 1

f(1) = 1 + 19 + 1 +19 = 40
