Answer:

912

Step-by-step explanation:

Answer:

[tex]Perimeter = 124m\\\\Length = 38m\\\\Perimeter = 2(length + breadth)\\\\124 = 2( 38 + breadth)\\\\62 = 38 + breadth\\\\breadth = 24m\\\\Area = length \times breadth = 38 \times 24 = 912m^2[/tex]

Answer:

3x² - 21x + 30

Step-by-step explanation:

y = 3(x - 5)(x - 2) ← expand factors using FOIL

  = 3(x² - 7x + 10) ← distribute parenthesis by 3

y = 3x² - 21x + 30 ← in standard form

Answer:

c = 3

Step-by-step explanation:

Given

[tex]\frac{2}{c-2}[/tex] - [tex]\frac{3}{c+2}[/tex] = [tex]\frac{7}{c^2-4}[/tex] ← factor the difference of squares

[tex]\frac{2}{c-2}[/tex] - [tex]\frac{3}{c+2}[/tex] = [tex]\frac{7}{(c-2)(c+2)}[/tex]

Multiply through by (c - 2)(c + 2) to clear the fractions

2(c + 2) - 3(c - 2) = 7 ← distribute and simplify left side

2c + 4 - 3c + 6 = 7

- c + 10 = 7 ( subtract 10 from both sides )

- c = - 3 ( multiply both sides by - 1 )

c = 3

Answer:

7/12 OR 0.58 (2.d.p)

Step-by-step explanation:

Product means that the two rational numbers are being multiplied to get 7.

The question also tells us that one of them is 12. Therefore we can write an equation to express this information where we represent the unknown rational number using the letter 'r':

r x 12 = 7

Rearrange to find r:

r x 12 / 12 = 7 /12

r = 7/12 = 0.5833....

= 0.58 (2.d.p)

Hope this helped!

Answer:

[tex]y = \frac{7}{12}[/tex]

Step-by-step explanation:

x × y = 7

We are given x = 12.

12 × y = 7

Rearrange.

y × 12 = 7

Divide each side by 12.

y × 12 ÷ 12 = 7 ÷ 12

Simplify.

[tex]y = \frac{7}{12}[/tex]

Actually Welcome to the concept of expo functions.

f(x) = -8(2)^x - 12 ,

for f(0) ,here substitute x = 0

so we get as ,

==> f(0) = -8(2)^0 -12

==> f(0) = -8-12

==> f(0) = -20

hence, f(0) = -20

Answer:

Step-by-step explanation:

If it went from f(x) ⟹ f(0), that means that x=0.

So, you would plug in 0 for x in f(x)=-8(2)^x-12.

After plugging in the value of x, x=0, into the equation, you should have

f(0)=8(2)^0-12

Now, we are solving for f(0) (or f(x)).

You would use PEMDAS to solve this:

P-PARENTHESIS

E-EXPONENT

M-MULTIPLICATION

D-DIVISION

A-ADDITION

S-SUBTRACTION

There are no parenthesis

there are exponents,

(2)^0 and that =1

so we have f(0)=8(1)-12

there is multiplication, 8(1) which =8

so now we have f(0)=8-12

there is no division

there is subtraction

8-12, which equals -4

f(0)=-4

Answer:

[tex]f(n) = 4n^2 + 4[/tex]

f(1) = 4 x 1 + 4 = 4 + 4 = 8

f(2) = 4 x 4 + 4 = 16 + 4 = 20

f(3) = 4 x 9 + 4 = 36 + 4 =40

f(4) = 4 x 16 + 4 = 64 + 4 = 68

Answer:

216 cm^2.

Step-by-step explanation:

Surface area = 2 * area of triangular sides + area of 3 rectangles

= 2 * 1/2 * 6 * 8 + 8*7 + 6 * 7 + 10*7

= 48 + 56 + 42 + 70

= 216.

Answer:

216cm^2

Step-by-step explanation:

The surface area is equal to the sum of areas of the walls.

We've got 2 triangular walls with area 6*8/2, for 6*8 = 48cm^2 total

We've got a wall with 7x10 = 70cm^2

We've got a wall with 6x7 = 42cm^2

And the last wall is 8x7 = 56cm^2

So total surface area is: 48 + 70 + 42 + 56 = 216

Answer: C

Step-by-step explanation:

Mistook the last one for different type of math apologies...

I just answered in the comments.

The correct answer is option C.

Let A : getting an odd number (i.e. 1,3 or 5), B: getting a number greater than 4 (i.e 5 or 6) . So, the required probability is  P(A∪B)=P(A)+P(B)−P(A∩B)=36+26−16=46=23

Answer:

r = [tex]2\sqrt{5}[/tex]

[tex](x - 3)^{2} + ( y - 2)^{2} = 20[/tex]

Is this a live test question or a homework question?

Step-by-step explanation:

the radius is the distance between (3, 2) and (5, -2)

[tex]r^{2}[/tex] = [tex]{(3 - 5)^{2} + (2 + 2)^{2} }[/tex]

    =  [tex](-2)^{2} + 4^{2}[/tex]

    =  4 + 16 = 20

r = [tex]\sqrt{20 } = 2\sqrt{5}[/tex]

Equation of circle:   [tex](x - 3)^{2} + ( y - 2)^{2} = 20[/tex]

Answer:

Radius: [tex]2\sqrt{5}[/tex]

Equation of circle: [tex](x-3)^2+(y-2)^2=20[/tex]

Step-by-step explanation:

The radius of a circle is equal to the distance between the center of the circle and any point on the circle. Therefore, we have:

[tex]r=\sqrt{(5-3)^2+(2-(-2))^2},\\r=\sqrt{2^2+4^2},\\r=\sqrt{20}=\boxed{2\sqrt{5}}[/tex]

The equation of a circle with radius [tex]r[/tex] and center [tex](h, k)[/tex] is given by:

[tex](x-h)^2+(y-k)^2=r^2[/tex].

What we know:

Substituting known values, we get:

[tex](x-3)^2+(y-3)^2=(2\sqrt{5})^2,\\\boxed{(x-3)^2+(y-2)^2=20}[/tex]

20 is the answer

Answer:

y= 36

Step-by-step explanation:

if y varies directly as x, and y=9 when x=4, find y when x=16

.

When you see "direct variation" think:

y = kx

.

To find k, use "y=9 when x=4":

y = kx

9 = k(4)

9/4 = k

.

so, our equation is:

y = (9/4)x

.

now, we can answer:

find y when x=16

y = (9/4)x

y = (9/4)(16)

y = (9)(4)

y = 36

Answer:

[tex]Sum = 64[/tex]

Step-by-step explanation:

Given

[tex]n = 55[/tex]

[tex]x \to 55\ digit[/tex] 1's

Required

The sum of the [tex]digits[/tex] of the [tex]product[/tex]

To do this, we start with smaller numbers

[tex]55*11 = 605[/tex]  ---- 2 digits

[tex]55*111 = 6105[/tex] --- 3 digits

[tex]55*1111 = 61105[/tex] -- 4 digits

[tex]55*11111 = 611105[/tex] -- 5 digits

[tex]55*111111 = 6111105[/tex] --- 6 digits

Notice that as the 1's increase on the left-hand side, the 1's increase on the right-hand side

The difference between the count of both 1's is 2 1's

So, for n digits, we have: 6[n - 2, 1's]05

So, the sum is:

[tex]Sum = 6 + (n - 2) + 0 + 5[/tex]

For 55 digit, [tex]n = 55\\[/tex]

So, we have:

[tex]Sum = 6 + (55 - 2) + 0 + 5[/tex]

[tex]Sum = 6 + 53 + 0 + 5[/tex]

[tex]Sum = 64[/tex]

Step-by-step explanation:

before taking the zeros each zeros were in the forrm

x+a=0 where 'a' is any number

then after taking the zeros, the zeros were in the form x=0 x=2 x=1

so we are gonna take then back to the form before taking the zeros
