Answers

Answer 1

Answer:

TSA=115.5cm²

Step-by-step explanation:

T.S.A=3πr²

Given r=3.5cm

eq.

3×22/7×3.5×3.5

=3×22×0.5×3.5

=115.5cm²

Answer 2

Answer:

[tex]19.25cm^{2} \\[/tex]

Step-by-step explanation:

Formula

[tex]\frac{\pi r^{2} }{2}[/tex]

Solve

[tex]\frac{(\frac{22}{7} )(3.5cm)^{2}}{2}= \frac{(\frac{22}{7} )(3.5cm)(3.5cm)}{2}=\frac{((\frac{22}{7} )(3.5cm))(3.5cm)}{2}=\frac{(\frac{77}{7}cm)(3.5cm) }{2}[/tex]=

[tex]\frac{(11cm)(3.5cm)}{2}=\frac{38.5cm^{2}}{2}=19.25cm^{2}[/tex]

Answers

Answer:

Julio's number is 31.

Step-by-step explanation:

Okay, so -70 divided by -5 is 14.

14 plus 17 equals 31.

If you subtract 17 from 31, you get 14.

Then, if you multiply 14 times -5, you get -70.

Answers

Answer:

Time, t = 9.615 secs.

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex] ....equation 1

[tex]Time = \frac{distance}{speed}[/tex] .....equation 2

Given the following data;

Distance = 100m

Speed = 10.4m/s

Substituting into equation 2;

[tex]Time = \frac{100}{10.4}[/tex]

Time, t = 9.615 secs.

The entry ticket to a local football game costs $12 for an adult and $8 for a child. A group of 100 people paid an entry fee of $1,056. How many adults and how many children were there in this group? Drag the correct value to the appropriate box.

Answers

Step-by-step explanation:

let x be the number of adults and y number of childrens

so we have. x+y=100 people

and. 12*x+8*y=1056 dollars

x=100-y

replace 100-y to the second equation

12*(100-y)+8y=1056

1200-12y+8y=1056

1200-4y=1055

1200-1056=4y

144=4y

y=144/4=36

so x=100-y=100-36=64

so in this group were 64 adults and 36 childrens

In this group were 64 adults and 36 children.

What is system of equation ?

In mathematics, a system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables.

let x be the number of adults and y number of children

so we have. x + y = 100 people

and. 12 × x + 8 × y = 1056 dollars

x=100 - y

replace 100 - y to the second equation

12 × (100 - y) + 8y = 1056

1200 - 12y + 8y = 1056

1200 - 4y = 1055

1200 - 1056 = 4y

144 = 4y

y = 144/4 = 36

so x = 100 - y = 100 - 36 = 64

Hence, in this group were 64 adults and 36 children.

5 + 4(8n - 8) = -1 + 6

First you have to distribute the 4 leaving the equation to look like this...

5 + 32n - 32 = -1 + 6

Now solve the constants (normal numbers without a variable)

-27 +32n = 5

Two buses are traveling to a state park. One bus leaves the terminal at 4:00 pm, and travels at 40 miles per hour. The second bus
leaves the terminal at 5:00 p.m. and travels at 60 miles per hour.
At what time does the second bus catch up with the first bus?

Answers

Answer:

Step-by-step explanation:

When the second bus catches up to the first bus, this means that the distance they have travelled is equal.

So for bus 1, you know it travels at 40 miles per hour.

4pm = 0 miles

5pm = 40 miles

6 pm = 80 miles

7pm = 120 miles

For bus 2, you know it travels at 60 miles per hour

5pm = 0 miles

6pm = 60 miles

7pm = 120 miles.

So you can see that at 7pm, they will both have travelled 120 miles.

Which translation maps the graph of the function f(x) = x2 onto the function g(x) = x2 + 2x + 6?
O left 1 unit, up 5 units
Oright 1 unit, up 5 units
left 2 units, up 2 units
Oright 2 units, up 2 units

Answers

Answer:

The translation is left 1 unit, up 5 units ⇒ A

Step-by-step explanation:

Let us revise the rules of translation of a function

If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)  If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)  If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k  If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k

The vertex form of the quadratic function is f(x) = ax² + bx + c, where a, b, and c are constant is f(x) = a(x - h)² + k, where h = [tex]\frac{-b}{2a}[/tex]  and k = f(h)

You will use the vertex form to find the translation

∵ g(x) = x² + 2x + 6

∴ a = 1 and b = 2

→ use the rule of h to find it

∴ h = [tex]\frac{-2}{2(1)}=\frac{-2}{2}[/tex]

h = -1

→ Use it to find k

∵ g(h) = k

∴ k = g(-1)

→ Substitute x by -1 in g to find k

∴ k = (-1)² + 2(-1) + 6 = 1 - 2 + 6

k = 5

→ Substitute the values of h and k in the vertex form above

∴ g(x) = 1(x - -1)² + 5

g(x) = (x + 1)² + 5

→ By using the 2nd and 3rd rules of translation above

f(x) is translated 1 unit to the left and 5 units up

∴ The translation is left 1 unit, up 5 units

The translation that maps the graph is mathematically given as

"The translation as left 1 unit, up 5 units"

Which translation maps the graph of the function f(x) = x2 onto the function g(x) = x2 + 2x + 6?

Translation is simply defined as the communication of the meaning of source content into target-content.

Generally, the equation for the  vertex form  is mathematically given as

g(x) = x² + 2x + 6

Where

a = 1 and b = 2 and h=-1

g(h) = k

k = g(-1)

k = (-1)² + 2(-1) + 6

k= 1 - 2 + 6

k = 5

In conclusion

g(x) = (x + 1)^2 + 5

Giving the translation as left 1 unit, up 5 units
