Answer:

7

Step-by-step explanation:

7 is the coefficient of X.

Reasoning? The coefficient is the number that comes before a variable. In this case, 7 is the coefficient of x.

And 2 is the coefficient of y.

Answer:

All of them

Step-by-step explanation:

Acute, right, scalene, equilateral, isosceles, and obtuse are ways to describe a triangle and classify it, especially with the type of angles it has. Acute can describe a 45-degree angle, just like right can describe a ninety-degree angle.

Answer:

B, D, and E

Step-by-step explanation:

Acute can never be right and Right cannot be equilateral

Step-by-step explanation:

Hello.

Plug in the values of the variables and solve:

5a+b²

5(-2)+6²

5 times -2 is equal to -10:

-10+6²

6² = 6×6=36

-10+36

Add:

26

And we're done!

Answer:

slope = -3

y-intercept = 2  

Step-by-step explanation:

The equation y = -3x + 2 is written in slope-intercept form of

y= mx +b where m is the slope and b is the y intercept.

m = -3

b= 2

Answer: Tides are the daily rise and fall in surface water levels of bays, gulfs, inlets and oceans and vary depending on the day and location. Tides are big periodic waves that move through the ocean in response to the gravitational attraction of the moon and the sun.

Step-by-step explanation: according to the National Oceanic and Atmospheric Administration (NOAA). Most coastal areas experience two high tides and two low tides every day and they may not be equal. (In some places, such as the Gulf Coast, you may only get one high and one low tide per day.) The height difference between high tide and low tide is called the tidal range. In some areas, the difference between high and low tides may not be so noticeable. In other areas, it can be quite stark.

We are given with the function [tex]{\bf{f(x,y,z)=e^{x+y}\cos (z)+(y+1)\sin^{-1}(x)at}}[/tex] and we need to find [tex]{\bf \nabla f}[/tex] , that's nothing but just the gradient of f(x,y,z) . But before starting let's recall ;

For a function F(x, y, z, ....) , the gradient is given by ;

So , now let's calculate the partial derivatives of f(x, y, z) first with respect to x , y and z one after other .So consider ;

[tex]{:\implies \quad \sf f(x,y,z)=e^{x+y}\cos (z)+(y+1)\sin^{-1}(x)at}[/tex]

Partial differentiating both sides w.r.t.x will yield ;

[tex]{:\implies \quad \sf \dfrac{\partial f}{\partial x}=e^{x+y}\cos (z)+(y+1)at\dfrac{1}{\sqrt{1-x^{2}}}}[/tex]

Simplifying will yield ;

[tex]{:\implies \quad \sf \dfrac{\partial f}{\partial x}=\dfrac{e^{x+y}\cos (z)\sqrt{1-x^{2}}+(y+1)at}{\sqrt{1-x^{2}}}}[/tex]

Now again consider ;

[tex]{:\implies \quad \sf f(x,y,z)=e^{x+y}\cos (z)+(y+1)\sin^{-1}(x)at}[/tex]

Partial differentiating both sides w.r.t.y will yield ;

[tex]{:\implies \quad \sf \dfrac{\partial f}{\partial y}=e^{x+y}\cos (z)+\sin^{-1}(x)at}[/tex]

Now , again consider ;

[tex]{:\implies \quad \sf f(x,y,z)=e^{x+y}\cos (z)+(y+1)\sin^{-1}(x)at}[/tex]

Partial differentiating both sides w.r.t.z will yield ;

[tex]{:\implies \quad \sf \dfrac{\partial f}{\partial z}=-e^{x+y}\sin (z)}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{\nabla f=\bigg\{\dfrac{e^{x+y}\cos (z)\sqrt{1-x^{2}}+(y+1)at}{\sqrt{1-x^{2}}}\bigg\}\hat{i}+\bigg\{e^{x+y}\cos (z)+\sin^{-1}(x)at\bigg\}\hat{j}-\bigg\{e^{x+y}\sin (z)\bigg\}\hat{k}}}}[/tex]

Answer:

The answer is 2095 cubic inches

step-by-step explaination:

Now,

V = 2/3 πr³

V = (2/3) × (22/7) × (10)³ inches

V = 44/21 × (10)³ inches

V = 2.095 × 1000 inches

V = 2095 cubic inches.

Thus, The volume of bowl is 2095 cubic inches.

Answer:  y = 340000*(1.094)^t

This is the same as writing [tex]y = 340000(1.094)^t[/tex]

======================================================

Explanation:

The answer above is in the form y = a*b^t

a = 340,000 = initial population

b = 1.094 = 1 + 0.094 = growth factor

Think of the growth factor as 100% + 9.4% = 109.4%
