one shot answer anyone know?

Answer:

8

Step-by-step explanation:

[tex]=\frac{1}{2}(a+b)-(a-b)\times2\\\\= \frac{1}{2}(18+14)-(18-14)\times2\\\\= \frac{1}{2}(32)-(4)\times2\\\\=16-8=8[/tex]

Answer:

[tex]\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}[/tex]

the question asks us to rationalise the given term ! thus , we'll just have to remove the √3 from th denominator anyhow !

let's start ~

[tex] \frac{2 \sqrt{5} }{7 - \sqrt{3} } \\ \\ \implies \: \frac{2 \sqrt{5} }{7 - \sqrt{3} } \: \times \: \frac{7 + \sqrt{3} }{7 + \sqrt{3} } = \frac{14 \sqrt{5} + 2 \sqrt{15} }{(7) {}^{2} - ( \sqrt{3) {}^{2} } } \\ \\ \implies \frac{14 \sqrt{5} + 2 \sqrt{15} }{49 - 3} \\ \\ \implies \frac{14 \sqrt{5} + 2 \sqrt{15} }{46} \\ \\ \implies \: \frac{\cancel{2}(7 \sqrt{5{} } \: + \sqrt{15} )}{\cancel{46} } \\ \\\bold\red{ \implies \: \frac{7 \sqrt{5} + \sqrt{15} }{23}}[/tex]

Using a system of equations, it is found that the numbers are 5 and -7.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, we say that the numbers are x and y.

They multiply to -35, hence:

xy = -35.

They add to -2, hence:

x + y = -2 -> y = -2 - x

Replacing on the first equation:

x(-2 - x) = -35

-x² - 2x + 35 = 0

x² + 2x - 35 = 0

(x + 7)(x - 5) = 0

x = -7 -> y = 5

x = 5 -> y = -7

Hence the numbers are 5 and -7.

Answer:

244 miles (nearest whole number)

Step-by-step explanation:

This scenario can be modeled as a geometric series.

From the information given:

The formula for the sum of the first n terms of a geometric series is:

[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

Therefore, the sum of the first 19 terms is:

[tex]\implies S_{19}=\dfrac{8(1-1.05^{19})}{1-1.05}[/tex]

[tex]\implies S_{19}=244.3120313...[/tex]

244 miles (to the nearest whole number)

So

It's a GP

we need Sum

[tex]\\ \rm\Rrightarrow S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

[tex]\\ \rm\Rrightarrow S_{19}=\dfrac{8(1-1.05^{19})}{1-1.05}[/tex]

[tex]\\ \rm\Rrightarrow S_{19}=\dfrac{−12.21560156300510578244137725830078125}{-0.05}[/tex]

[tex]\\ \rm\Rrightarrow S_{19}=244.312\approx 244mi[/tex]

The binomial factor of the equation [tex]\rm 9x^2 -64[/tex] is 3x-8.

The algebraic expression which contains only two terms is called binomial. It is a two-term polynomial. Also, it is called a sum or difference between two or more monomials.

Factoring binomials means breaking down a binomial expression into its simplest form.

Binomials are algebraic expressions with two terms.

The given binomial is;

[tex]\rm 9x^2 -64[/tex]

The binomial is determined in the following steps given below.

[tex]\rm =9x^2 -64\\\\= (3)^2x^2-8^2\\\\= (3x)^2-8^2\\\\= (3x-8)(3x+8)[/tex]

Hence, the binomial factor of the equation [tex]\rm 9x^2 -64[/tex] is 3x-8.

The ladder and the wall it leans on are illustrations of right triangle

The horizontal distance from the base of the ladder is 5.41 feet

The given parameters are:

Length (L) = 26 feet

Angle of elevation (θ) = 78 degrees

The horizontal distance (D) is calculated using the following cosine ratio

cos(θ) = D/L

Substitute known values

cos(78) = D/26

Make D the subject

D = 26 * cos(78)

Multiply

D = 5.41

Hence, the horizontal distance from the base of the ladder is 5.41 feet

Answer:

x = 8 - sqrt(y + 25)

Step-by-step explanation:

Step-by-step explanation:

comparing given equation with ax^2+bx+c;

a=1   b=-16   c=39

now,

x coordinate of vertex = -b/2a

                                      = 16/2*1

                                     = 8

again,

y coordinate of vertex = (8)^2-16(8)+39

                                       =-25

Therefore, the turning point is (8,-25).

Right Triangles

Step-by-step explanation:

This is because in a right angled triangle, there is one angle that is equal to 90 degrees, and 2 that are 45 degrees each.

These 45 degree corners make up the corners of the square (45+45 = 90 = right angle = corner of square)

i think since p(x) = p(3)

Step-by-step explanation:

then p(3) = 3

where you see x add 3

so 1/2(x-5)^2 + 14

1/2(3-5)^2 + 14

1/2(-2)^2 + 14

1/2 x 4 + 14

cancel out 4 by 2 ( divide)

you get 2 + 14
