Step-by-step explanation:

By definition,  the constant difference for a hyperbola is:

d = |PF1 - PF2|

where PF1 is the distance between points P and F1, and PF2 is the distance between points P and F2

Let's call F1 to (-3, 0), F2 to (3, 0) and P (7, 0). Then, the distances are:

PF1 = √[(-3 - 4)² + (0 - 0)²] = 7

PF2 = √[(3 - 4)² + (0 - 0)²] = 1

And the the constant difference is:

d = |7 - 1| = 6

Step-by-step explanation:

Answer: 0.5

( f + g ) (x) = –2x + 6

( f – g ) (x) = 8x – 2

( f  × g ) (x) = –15x2 + 2x + 8

)(x)=  

4−5x

3x+2  f (2) = 2(2) = 4

g(2) = (2) + 4 = 6

h(2) = 5 – (2)3 = 5 – 8 = –3

Now I can evaluate the listed expressions:

(f + g)(2) = f (2) + g(2)

= 4 + 6 = 10

(h – g)(2) = h(2) – g(2)

= –3 – 6 = –9

(f × h)(2) = f (2) × h(2)

= (4)(–3)= –12

(h / g)(2) = h(2) ÷ g(2)

= –3 ÷ 6 = –0.5

​

Step-by-step explanation:

By looking where the functions intercept, we conclude that the correct option is x = -2.8.

Here we have:

To find a solution of f(x) = g(x), we can graph both equations on the same axis, and see where the curves intercept.

The graph can be seen below:

There, we can see that we have intercepts at:

x = -2.8

x = 0.8

x = 2.9

From these, the only one that appears in the options is the first one, so that is the correct option.

Answer:

total paper required = 57 cm²

Step-by-step explanation:

given data

slant height b = 4 cm

base side h = 3 cm

block height  h1 = 2 cm

solution

we get surface area of right squared pyramid by add here areas of all 4 triangles that is express as

area = 4 × Area of Triangles

area = 4 × [tex]\frac{bh}{2}[/tex]  

area = 4 × [tex]\frac{4\times 3}{2}[/tex]  

area = 24 cm²

and

surface are of the box is equal to the area of its 4 side faces + base

area = 4 × ( h × h1 ) + h²  

area = 4 × ( 3 × 2 ) + 3²

area = 24 + 9

area = 33 cm²

so total paper required = 24 + 33

so total paper required = 57 cm²

The product of the expressions is 1/3a option the second 1/3a is correct after simplification.

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

[tex]=\rm \dfrac{a-3}{15a} \times \dfrac{5}{a-3}[/tex]

After simplification:

[tex]=\rm \dfrac{1}{15a} \times \dfrac{5}{1}[/tex]

Answer:

18.6 inches

Step-by-step explanation:

As we have the scale between the model and the real skyscraper, and we also have the height of the real building, to find the height of the model we just need to use a rule of three:

1 inch -> 75 feet

x inches -> 1395 feet

x*75 = 1*1395

x = 1395 / 75

x = 18.6 inches

The height of the model skyscraper is 18.6 inches.

The trampoline is 10 units off the ground.

The maximum height of the acrobat is 18 units, and it takes 1 second to reach this height.

We have,

To find the height of the trampoline off the ground, we need to determine the value of f(x) when x is equal to zero.

This is because at the moment the acrobat jumps (x=0), the height of the acrobat is the height of the trampoline.

Given the function f(x) = -8x² + 16x + 10, we substitute x=0 into the function:

f(0) = -8(0)² + 16(0) + 10

f(0) = 0 + 0 + 10

f(0) = 10

Now,

To find the maximum height of the acrobat and the time it takes to reach this height, we can observe that the function f(x) is in the form of a quadratic equation in the form of ax² + bx + c, where a = -8, b = 16, and c = 10.

The maximum height of the acrobat occurs at the vertex of the quadratic function.

The x-coordinate of the vertex is given by:

x = -b / (2a)

Substituting the values, we have:

x = -16 / (2 * -8)

x = -16 / -16

x = 1

The time it takes to reach the maximum height is 1 second.

To find the maximum height, substitute the value of x back into the function:

f(1) = -8(1)² + 16(1) + 10

f(1) = -8 + 16 + 10

f(1) = 18

Therefore,

The trampoline is 10 units off the ground.

The maximum height of the acrobat is 18 units, and it takes 1 second to reach this height.

Answer:

-20

Step-by-step explanation:

because if you put -20 over 4, that simplifies out to -5

Answer:

x= -20

Step-by-step explanation:

To solve this problem, we have to get x by itself.

x/4= -5

x is being divided by 4. To reverse this, multiply both sides by 4, because multiplication is the opposite of division.

4*(x/4)=(-5)*4

The 4s on the left cancel, so we are left with:

x=-5*4

x=-20

To check our solution, we can substitute -20 back in for x.

x/4=-5

-20/4=-5

-5= -5

This is true, so we know that -20 is the solution.
