Answer:

± 5

Step-by-step explanation:

$\sqrt{25}$ = 5 or - 5 , written ± 5 ( ± plus or minus )

Since 5 × 5 = 25 and - 5 × - 5 = 25

➷ Square rooting is when you find the number that multiplied by itself to make that value.

In this case, we know 5 x 5 = 25

However, - 5 x -5 = 25

Therefore, the answer is 5 or -5

what is the value of a for the exponential function in the graph represented in the form of f(x)=a(b^x)? Zoom in the photo bcz i

nekit [7.7K]

Answer:

$a = 3$

Step-by-step explanation:

To determine the value of $a$ , we want $b^x$ to be 1, so that $f(x) = a \times 1$ . Notice that if $x = 0$ , then $f(0) = a \times (b^0) = a$ , so the value of $a$ is simply $f(0)$ . From the graph, it appears that $f(0) = 3$ , so therefore $a = 3$ .

Please Help!! Find the Polynomial!!

grin007 [14]

Answer:

$\pi x^2-8\pi x+16\pi$

Step-by-step explanation:

To find the area of the inner circle, we need to find its radius. Here, we can write the radius as 4 - x. Now, we can use the formula $A=\pi r^2$ :

A = $\pi$ * $(4-x)^2$

We can expand the square:

A = $\pi *(16-8x+x^2)=\pi x^2-8\pi x+16\pi$

Thus, the polynomial is $\pi x^2-8\pi x+16\pi$ .

Hope this helps!

Find x and y. Please help, I will give brainiest answer.

Inessa05 [86]

Answer:

x = 3 and y = 2

x = 1.25 and y = 1.75

Step-by-step explanation:

Part 1:

See the diagram first.

If the two arrow lines are parallel then, the two triangles are similar.

So, the corresponding sides of the triangles are proportional.

So, $\frac{3}{1.5} = \frac{6}{x} = \frac{4}{y}$

Hence, x = 3 and y = 2 (Answer)

Part 2:

See the diagram first.

If the two arrow lines are parallel then, the two triangles are similar.

So, the corresponding sides of the triangles are proportional.

So, $\frac{10}{8} = \frac{x + 5}{5} = \frac{y + 7}{7}$

⇒ $x + 5 = \frac{50}{8} =6.25$

⇒ x = 1.25

Again, $y + 7 = \frac{70}{8} =8.75$

⇒ y = 1.75

Hence, x = 1.25 and y = 1.75 (Answer)

If sin a= 12/13 and tan B 8/15 and angles a and b are in qundrant 1 find the value of tan (a+b)

natali 33 [55]

Answer:

The value of Tan (a + b) is $\frac{-220}{21}$ .

Step-by-step explanation:

Given as :

Tan b = $\frac{8}{15}$

Sin a = $\frac{12}{13}$

∵Sin Ф = $\dfrac{\textrm perpendicular}{\textrm Hypotenuse}$

So, $\dfrac{\textrm perpendicular}{\textrm Hypotenuse}$ = $\frac{12}{13}$

Now, Base² = Hypotenuse² - Perpendicular²

Or, Base² = 13² - 12²

Or, Base² = 169 - 144

Or, Base² = 25

∴ Base = $\sqrt{25}$ = 5

And Tan Ф = $\dfrac{\textrm perpendicular}{\textrm Base}$

Or, Tan a = $\frac{12}{5}$

Now, Tan (a + b) = $\dfrac{Tan a + Tan b}{1- Tan a Tanb}$

Or, Tan (a + b) = $\frac{\frac{12}{5}+\frac{8}{5}}{1-(\frac{12}{5}\times \frac{8}{15})}$

or, Tan (a + b) = $\frac{\frac{36+8}{15}}{\frac{75-96}{75}}$

or, Tan (a + b) = $\frac{\frac{44}{15}}{\frac{-21}{75}}$

Or, Tan (a + b) = $\frac{-220}{21}$

Hence The value of Tan (a + b) is $\frac{-220}{21}$ . Answer
