HELLPPP ITS ABOUT FUNCTIONS EXPLANATION NEEDEDD HELPPP

Answer:

-x^2 +x

Step-by-step explanation:

f(x) = 1-x^2

g(x) = 1 - x

f(x) - g(x) = 1-x^2  - (1 - x )

Distribute the minus sign

              = 1-x^2 -1 +x

Combine like terms

             = -x^2 +x

Pythagorean’s theorem

Answer:

w=2

Step-by-step explanation:

A=length times width (A=lw)

w= l-3

A=10

Substituting in, we get:

10= l(l-3)

Now, solve the equation.

10= [tex]l^{2}[/tex]-3l

[tex]l^{2}[/tex]-3l-10=0

(l+2) (l-5)=0 (factoring the equation)

Therefore, l= -2 or 5

Throw out the negative value because a length of rectangle will never be negative.

Now let's solve for width

Remember w=l-3

therefore

(5)-3=2

so, w=2

(honestly, this is easier to just do in your head. But here is the long form math if you happen to run into more complicated problems.)

Answer:

w=2 l=5

Answer:

D

Step-by-step explanation:

If 2 tangents are drawn to a circle from the same external point then they are congruent.

AG and AE are tangents to the circle from the same external point, thus

AG is congruent to AE

AG is congruent to AE. Then the correct option is D.

In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.

If two tangents are drawn to a circle from the same external point then they are congruent.AG and AE are tangents to the circle from the same external point.

Hence, the correct option is D.

Answer:

184

Step-by-step explanation:

y + j + p + a = 1026

y - 60 = j/4 -------> y =  (j/4) + 60

p + 150 = j/2 -----> p = (j/2) - 150

2a = j -------> a = j/2

y = ?

y + p + j + a = 1026

(j/4) + 60 + (j/2) - 150 + j + (j/2) = 1026

(j/4) + j + j - 90 = 1026

(j/4) + 2j = 1116

9j/4 = 1116

9j = 4464

j = 496

y = (496/4) + 60 = 184

Step-by-step explanation:

Pls brainliest!!

There are many possible answers for this.

One example is below.

S = the number of stations included when a person orders basic cable, write an expression for the number of stations a person has if he ordered basic cable and 7 premium channels.

We can represent this as s + 7.

The value that we don't know is the number of

stations included when a person orders basic cable.

So we can represent that as s.

Then, since the person ordered 7 premium channels, that means he

is adding an additional 7 channels to his basic cable plan.

So we can represent this as s + 7.

Answer:

a number plus 7

Step-by-step explanation:

Answer

60 apples minus how many she picked (12) or 60-12 divided by 6 baskets. The answer will be 60-12=48. 48 divided by 6 equals 8. The ANSWER IS 8

Step-by-step explanation:

The formula used to calculate how many apples should be included in each gift basket is as follows:

6x = 48

A permutation is an orderly arrangement of things or numbers. Combinations are a means to choose items or numbers from a collection or set of items without worrying about the items' chronological order.

Jack has 48 apples left after using 12 of the 60 apples he took from the tree to make applesauce.

The leftover apples will be distributed equally among six gift baskets, he said. He puts x apples in each present basket, where x is the number of apples. Then he adds six times as many apples to each of the six gift baskets.

He has to fill the gift baskets with 48 apples, thus we can create an equation:

6x = 48

We may divide both sides of the equation by 6 after finding the value of x:

x = 8

Hence, Jack needs to fill each of the six gift baskets with 8 apples.

#SPJ2

Answer:

99.87%

Step-by-step explanation:

We would be using the Z score formula to solve this question. The formula is given as:

z = (x-μ)/σ,

Where :

x = observed value = 9.4lbs

μ = mean or average value = 7.9lbs

σ = Standard deviation = 0.5lbs

z = (9.4- 7.9)/0.5

z = 3

The z score = 3

Using the normal distribution table to find which percentage of babies would be at least 9.4lbs

P(x<Z) = 0.99865

Converting this to percentage = 0.99865 × 100 = 99.865%

Approximately = 99.87%

Therefore, the percentage of babies would be at least 9.4 lbs = 99.87%

Answer:

396 cm²

Step-by-step explanation:

The figure is composed of 2 rectangles.

The vertical rectangle on the left has area (A) calculated as

A = 27 × 10 = 270 cm²

The horizontal rectangle on the right has area (A) calculated as

Answer:

The table of data is shown below

The equation of line best fit is given in the form y=mx+b

to find the slope 'm', follow these steps:

STEP 1

Mean (X) = \frac{4+6+8+13+11}{5}=8.4

Mean(Y)= \frac{17+12+9+4+3}{5}=9

STEP 2

Refer to Picture 2 and Picture 3 for the working out of ( x_{i} -mean(X)) and ( y_{i} -mean(Y))

( x_{i}-X)( y_{i}-Y) =(-4.4)(8)+(-2.4)(3)+(-0.4)(0)+(2.6)(-5)+(4.6)(-6)

( x_{i}-X)( y_{i}-Y) =(-35.2)+(-7.2)+0+(-13)+(-27.6)=-83

STEP 3:

( x_{i}-X) ^{2}  = (-4.4)^{2}+ (-2.4)^{2}+ (-0.4)^{2}+ (2.6)^{2}+ (4.6)^{2}=53.2

STEP 4:

To find slope, divide answer in STEP 2 by the answer in STEP 3

m= \frac{-83}{53.2} =-1.56

STEP 5:

b=Mean(Y)-[slope*mean(X)]

b=9-(-1.56*8.4)=22.105

We have the slope, m=-1.56 and y-intercept of 22.105

The equation of line is

y=22.105-1.560x

Answer:

Aaron travelled about 9 feet underwater

Step-by-step explanation:

We need to work with the information we are given in the question.

there are two stages of Aaron's travel. the first distance was in the air, and the second distance was in the water.

We are given both the total distance travelled and the distance travelled in the air.

To get the distance travelled in water, we subtract the distance travelled in the air from the total distance.

This will be 52 feet - 43 feet = 9 feet

Hence Aaron travelled about 9 feet underwater

Answer:

The other two co-ordinates are (-3, 5) and (-8, 5).

Step-by-step explanation:

Consider the rectangle ABCD.

A = upper-left coordinates = (-8, 8)

B = upper-right coordinates = (-3, 8)

C = lower-left coordinates

D = lower-right coordinates

Let the side AB form the length of the rectangle.

Compute the distance between the points A and B as follows:

[tex]AB=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]

      [tex]=\sqrt{(-3+8)^{2}+(8-8)^{2}}\\=\sqrt{(5)^{2}}\\=5[/tex]

The length of the rectangle ABCD is 5 units.

The are of ABCD is given as 15 square units.

Compute the breadth of the rectangle as follows:

[tex]\text{Area}=\text{l}\times\text{b}\\15=5\times\text{b}\\b=3[/tex]

So, the breadth of the rectangle is 3 units.

Then from point B, 3 units below would be (-3, 5).

And from point A, 3 units below would be (-8, 5).

The rectangle on the coordinate plane is attached below.
