Pls include steps...
​

Answers

Answer 1

Answer:

n = -4

Step-by-step explanation:

[tex](\frac{5}{3} )^2^n^+^1 * (\frac{5}{3} )^5 = (\frac{5}{3})^n^+^2[/tex]

in multiplication if the base are same u can add there exponent.

[tex](\frac{5}{3})^2^n^+^1^+^5 = (\frac{5}{3})^n^+^2[/tex]

base of both sides are equal so their exponent will be equal

2n + 1 + 5 = n + 2

2n + 6 = n + 2

2n - n = 2 - 6

n = -4

In the following figure ABCD, find the value of x​

Answers

Answer:

80°

because its diagnol so the one in the top corner is the same as x

Answer:

x = 140°

Step-by-step explanation:

Sum of exterior angles of polygon is 360°

That is, x + 70 + 80 + 70 = 360

           x + 220 = 360

           x = 360 - 220 = 140°

The product of two 2-digit numbers is 3774. What is the smaller of the two numbers?

Please help quick

Answers

Answer:

In factored form:  3774  =  2 · 3 · 17 · 37

Creating two two-digit numbers:  3 · 17  =  51  and 2 · 37  =  74.

So, the two numbers are:  51  and  74.

Answer:

We would use the explicit formula since the explicit formula is used for finding the nth term in a sequence. The reason why it's not the recursive is because the recursive formula helps you find the next terms using a formula of the preceding term or term before the next term.

Answer:

39 ft^2

Step-by-step explanation:

area of small rectangle

length = 3 ft

breadth = 1 ft

area of rectangle = l*b

=3*1

=3 ft^2

area of big rectangle

length = 12 ft

breadth = 3 ft

area of rectangle = l*b

=12*3

=36 ft^2

area of the figure = area of small rectangle + area of big rectangle

=3 + 36 ft^2

=39 ft^2

39 square feet

Explanatiin:
Divide shape into 2 rectangles:

Area of upper rectangle;
1 • 3 = 3 ft2

Area of lower rectangle:
3 • 12 = 36 ft2

Add both areas of rectangles:
36 + 3 = 39 ft2

f(x) = x +1 g(x) = x^2 - 3
find f 3
find gf3

Answers

Given: f(x) = x + 1 and g(x) = x²−3

1. Solve for f(3)

Let f(x) = f(3).

Substitute 3 for x

f(3) = 3 + 1
= 4

Therefore f(3) = 4


Solve for gf(3)

Substitute f(3) into g(x).

f(3) = 4
gf(3) = 4² − 3
= 13

Therefore gf(3) = 13
