Answer:

D

Step-by-step explanation:

Leave everything the same except you add -5 and 2 =-3

Answer:

y=1/3x + 2

Step-by-step explanation:

Since slope intercept form is y=, I first added x to each side to get x on the other side. Then I divided each side by 3 to get y, and ended up with y=1/3x+2 as my answer.

(hope this helps)

Answer:

x=-1/4

Step-by-step explanation:

-4/16=16x/16

-1/4=x

Answer:

f*g(x) =  -25

Step-by-step explanation:

f*g(x) = f(x) * g(x) = x² * (3x + 14)

f*g(x) = (-5)² * (3*-5 +14) = 25 * (-1) = -25

Answer:

An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Gravity pulls denser air and water downward, forcing less dense air and water to move upward.

Answer:

The picture is to blurry to read

Step-by-step explanation:

Given that,

The given expression is : [tex]16x^0+2x^2{\cdot}y^{-1}[/tex]

To find,

The value of the above expression when x = 2 and y = 4

Solution,

We have,

[tex]16x^0+2x^2{\cdot}y^{-1}[/tex]

Put x = 2 and y = 4 in the above expression.

[tex]16x^0+2x^2{\cdot}y^{-1}\\\\=16\times (2)^0+2(2)^2\times (4)^{-1}\\\\=16\times 1+2(2)^2\times\dfrac{1}{4}\\\\=16+2\\\\=18[/tex]

So, the value of the above expression is 18.

Answer:

D

Step-by-step explanation:

(-8) - (-8) = (-8) + 8 = 0

Answer:

Step-by-step explanation:

volume=1/3 πr²h

=1/3×π×3²×4

=12π ft³

≈37.70 ft³

Here we have to calculate the volume of the cone which is provided in the figure.

As we know that volume of cone is calculated by the formula :

Here,

We have :

Putting the values in the formula :

[tex]\longrightarrow \: \sf{V \: = \: \dfrac{1}{3} \: \pi \:r {}^{2}h } \\ \\ \longrightarrow \: \sf{V \: = \: \dfrac{1}{3} \: \times \dfrac{22}{7} \:(3) {}^{2}(4) } \\ \\ \longrightarrow \: \sf{V \: = \: \dfrac{1}{3} \: \times \dfrac{22}{7} \:(3 \times 3)(4) } \\ \\ \longrightarrow \: \sf{V \: = \: \dfrac{1}{3} \: \times \dfrac{22}{7} \:(9)(4) } \\ \\ \longrightarrow \: \sf{V \: = \: \dfrac{1}{3} \: \times \dfrac{22}{7} \: \times 9(4) } \\ \\ \longrightarrow \: \sf{V \: = \: \dfrac{1}{3} \: \times \dfrac{22}{7} \: \times 9 \times 4 } \\ \\ \longrightarrow \: \sf{V \: = \: \dfrac{1}{ \cancel3} \: \times \dfrac{22}{7} \: \times \cancel9 \times 4 } \\ \\ \longrightarrow \: \sf{V \: = \: \dfrac{1}{1} \: \times \dfrac{22}{7} \: \times 3 \times 4 } \\ \\ \longrightarrow \: \sf{V \: = \: \dfrac{22}{7} \: \times 3 \times 4 } \\ \\ \longrightarrow \: \sf{V \: = \: \dfrac{22 \times 3 \times 4}{7} } \\ \\ \longrightarrow \: \sf{V \: = \: \dfrac{66 \times 4}{7} } \\ \\ \longrightarrow \: \sf{V \: = \: \dfrac{264}{7} } \\ \\ \longrightarrow \: \sf{V \: = \: \cancel\dfrac{264}{7} } \\ \\ \longrightarrow \: \underline{\underline{\red{\bf{V \: = \: 37.7 }}}}[/tex]

Answer:

Step-by-step explanation:

According to the given description, PS is the mid segment of the [tex] \triangle TQR[/tex]

Therefore by Mid-segment Theorem:

[tex]PS = \frac{1}{2} QR \\ \\ PS = \frac{1}{2} \times 32 \\ \\ PS =16 \: [/tex]

Answer:

Y=3/7x+8 and y=-7/3x-34/3(11 1/3)

Step-by-step explanation:

for the perpendicular line, the slope is the opposite inverse (3/7) and since 3/7×-7=-3, -3+8=5, hence, y=3/7x+8.

for the parallel line the slope is the same, and since -7/3×-7=49/3,

and 49/3-15/3(5)=34/3, the equation is y=-7/3-34/3

Given:

Total number of students = 20

The marks of the students are 40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37 and 40.

To find:

The frequency distribution table with class size 10.

Solution:

We have, the marks of 20 students.

40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37, 40

Here,

Minimum value = 12

Maximum value = 48

We nee class intervals of size 10. So, the required class intervals are 10-20, 20-30, 30-40, 40-50. In these intervals, lower limit is excluded but the upper limit included.

The required frequency distribution table is

Class intervals      Marks                                                  Frequency

10-20                    12, 15                                                            2

20-30                   22, 27, 20, 25                                             4

30-40                   36, 30, 31, 34, 36, 39, 36, 37                      8

40-50                   40, 41, 43, 48, 46, 40                                  6

Total                                                                                        20

Therefore, the frequency distribution table is

Class intervals:      10-20        20-30        30-40         40-50         Total

Frequency      :          2                4                8                6                20

X^2=a^2+b^2

X^2=15^2+8^2

x^2=225+64

x^2=289

x=17

Edge 2021

Answer:

x²+6x +8 ≥ 195

Step-by-step explanation:

The age of C is represented by  c=  x .

Building B was built two years before building C.

Age of Building B   b = x+ 2

Building D was built two years before building B

Age of Building d= x+4

The product of the building B’s age and building D’s age is at least 195.

b*d ≥ 195

≥ means product is greater than or equal to 195 at least 195

Putting the values of b and d

(x+ 2) (x+4) ≥ 195

It can be further solved

x²+6x +8 ≥ 195

Answer:

x^2+6x+8>195

Answer:

n = -4, -1/3.

Step-by-step explanation:

3n^2 + 13n+4= 0

3n^2 + 12n + n + 4 = 0

3n(n + 4) + 1(n + 4) = 0

(3n + 1)(n + 4) = 0

n = -4, -1/3.

Answer:

The answer would be Scale factor of 3

Answer:

36.5

Step-by-step explanation:

To find the median, list the ages in order from smallest to largest

23, 26 , 26,  35, 38 , 45, 50 ,63

Then find the middle

23, 26 , 26,  35,    38 , 45, 50 ,63

It is halfway between 35 and 38

(35+38)/2 = 36.5

The median is 36.5
