Answer 1

Answer:

D. 2^7

Step-by-step explanation:

2^3 x 2^4 would equal 128. So, if you do the math for all of them:

A isn't correct because it equals 16.

B isn't correct because it equals 4096.

C isn't correct because it equals 16384.

D is correct because 2^7 is 128.

​A model of an Egyptian pyramid has a slant height of 18 centimeters and a 15-centimeter square base. What is the surface area of the pyramid?

PLZ ANSWER QUICKLY AND ACCURATELY WILL MARK BRAINLIEST

Answers

Answer:

here is an example to guide you

Step-by-step explanation:

To find how much paper for the model, you will use the formula for area of a square and area of a triangle.

A = bh

7.2 x 7.2

A = 51.84 cm²

A = 1/2bh

1/2 x 7.2 x 6

A = 21.6 cm²

21.6 cm² x 4 = 86.4 cm²

86.4 + 51.86=138.3

You will need 138.3 cm² of paper.

Where do the slope and y-intercept show up in the tables and graphs?

Answers

Answer:

Solution: The general form of the line on a graph is y = mx+c,

where y is the coordinate of the point along the y-axis,

x is the coordinate of the point along the x-axis,

m is the slope of the line or arc tan of the angle the line makes with the x-axis, and

c is the intercept the line makes on the y-axis.

Suppose we want a line having a slope of 45º with the x-axis and passes through point P (4,6), the equation of the line is

y = mx + c

6 = tan 45 * 4 + c, or

6 = 4 + c, or

c = 6–4 = 2.

The origin is the point (0,0) where the x and y axis intersect. To get to the point (-1,1) start at the origin, move one unit to the left and one unit up. To get to the point (1,-1.5) start at the origin and move one unit right and down one and a half. To get to the point (2, 1/4) start at the origin and move 2 units right and up one fourth of the way to 1.

the diagonal of a square has a length of 10. what is the area of the square?

Answers

Answer:

50

Step-by-step explanation:

Diagonal of square = 10

Use special triangles to find the area because a square's diagonal divides the 90 degree angles into 45 degrees

45-45-90 triangle

x   : x   : x√2

1   : 1      : 10

10=x√2

10/√2=x, rationalize denominator and you get 5√2 as the square's side length

Area is s^2, s being the length of a side

(5√2)^2=25*2=50

Answer:

y intercept : if jada doesn't sell anything, she loses $250

Pos/neg interval: jada needs to sell more than 35 kilos in order to make a profit

Increase/decrease interval: the more paprika she sells, the more profit she makes

Step-by-step explanation:

y intercept is when she sells 0 kilos and is at -250 on the y axis

pos/neg interval is whether or not she is above or below 0 on the x axis (she has to be above it in order to make a profit)

The more the line is increasing, the larger profit she makes

Functions, f and g are given by f(x)= 3+ cos x and g(x) = 2x, x is a real number. Determine the value of c for which f(g(x))= g(f(x)) where 0[tex]\leq[/tex]x<2[tex]\pi[/tex]

Answers

The value x is equal to [tex]\pi[/tex] for which f(g(x))=g(f(x))

Given :

f(x)=3+cos(x)

g(x)=2x

To find : the value of x over the given interval [tex]0\leq x\leq 2\pi[/tex]

Apply composition of functions. Replace g(x) inside f(x) to find f(g(x))

[tex]f(g(x))=f(2x)=3+cos(2x)\\g(f(x))=g(3+cosx)=2(3+cosx)\\[/tex]

Now we set f(g(x))=g(f(x)) and solve for x

[tex]3+cos(2x)=2(3+cosx)\\3+cos(2x)=6+2cos(x)\\\cos \left(2x\right)-2\cos \left(x\right)-3=0\\\\we \; know:\ cos(2x)=2cos^2(x)-1\\-4-2\cos \left(x\right)+2\cos ^2\left(x\right)=0\\2cos^2(x)-2cos(x)-4=0\\\\divide \; by \; 2 \; and \; Factor \; left \; hand \; side\\\\cos^2(x)-cos(x)-2=0\\\\(cosx-2)(cosx+1)=0\\\cos \left(x\right)=2,\:\cos \left(x\right)=-1[/tex]

cos(x)=2 cannot be solved , so no solution

[tex]cos(x)=-1\\cos is -1 at x=180 degree\\So , x=\pi[/tex]
