289 -> 290

7 -> 10

290 x 10

= 2900

The best estimate would be the product of 290*10, which is 2,900. So if you were to multiply 289 and 7, the answer would be somewhere around 2,900.

I hope this helped!

Diana owns a novelty shop in downtownSan Antonio. She ordered a shipment of48 party hats. Of the 48 hats that sheordered, 25% we
ioda

We can calcualte the number of blue hats by multiplying the total number of hats (n=48) by the proportion of blue hats (p=25%=0.25).

Then:

B=n\cdot p=48\cdot0.25=12

There are 12 blue hats.

Find the simplified quotient of y^2+y/y^2-2y/4y+4/y^2-4y+4
babunello [35]

Answer:

y4 - 8y3 + 8y2 + 2y + 8

 —————————————

           2y2          

Step-by-step explanation:

Step  1  :

            4

Simplify   ——

           y2

Equation at the end of step  1  :

            y       y       4

 (((((y2)+————)-((2•—)•y))+——)-4y)+4

          (y2)      4      y2

Step  2  :

           y

Simplify   —

           4

Equation at the end of step  2  :

            y       y       4

 (((((y2)+————)-((2•—)•y))+——)-4y)+4

          (y2)      4      y2

Step  3  :

            y

Simplify   ——

           y2

Dividing exponential expressions :

3.1    y1 divided by y2 = y(1 - 2) = y(-1) = 1/y1 = 1/y

Equation at the end of step  3  :

          1  y2   4

 (((((y2)+—)-——)+——)-4y)+4

          y  2   y2

plz mark me as brainliest :)

What is the value of a for the exponential function in the graph represented in the form of f(x)=a(b^x)
Rina8888 [55]

<em><u>Note: The complete question, along with the graph, is attached below.</u></em>

<em><u /></em>

Answer:

The value of a = 3

Step-by-step explanation:

Given the function

f\left(x\right)=a\left(b^x\right)

From the attached graph, it is clear that

at x = 0,

f\left(0\right)=a\left(b^0\right)

\:f\left(0\right)\:=\:a\:\times \:1         ∵ b^0=1

f\left(0\right)=a

Thus

When x = 0, the y-intercept will be:

f\left(0\right)=a

From the attached figure, it is clear that

at x = 0, the value of y = 3

so

putting y = 3 in the equation

f\left(0\right)=a

3 = a            ∵ f\left(0\right)=y=3

Therefore, the value of a = 3
