Answer:

HI = 8

TU = 45

Step-by-step explanation:

→ Find the scale factor enlargement

45 ÷ 10 = 4.5

→ Multiply JI by the scale factor to find it

10 × 4.5 = 45

→ Divide UV by the scale factor to find it

36 ÷ 4.5 = 8

The explicit formula for a sequence is<br> an=−2+3/2(n−1)<br> What is the 21st term of the sequence?
Anni [7]

Step-by-step explanation:

From the given question it appears that (n-1) is in the numerator's place, if it is so, then let us solve it.

a_n =  - 2 +  \frac{3}{2}(n - 1)   \\ \\  \therefore \: a_{21} =  - 2 +  \frac{3}{2}  (21 - 1) \\  \\   \therefore \: a_{21} =  - 2 +  \frac{3}{2 }   \times \: 20\\  \\ \therefore \: a_{21} =  - 2 + 3 \times \: 10  \\  \\ \therefore \: a_{21} =  { -2  + 30}   \\  \\ \therefore \: a_{21} =  28   \\  \\  \huge \red{ \boxed{\therefore \: a_{21} =   28}  } \\  \\

What is the value of r (3,4), (-1,r),m=-3/4
Llana [10]

To find the value of r

We will follow the steps below

Usinf the equation of a slope:

slope(m) =

m=\frac{y_2-y_1}{x_2-x_1}

from the question given;

m= -3/4

x₁ = 3

y₁=4

x₂=-1

y₂=r

substituting the values into the slope formula

\frac{-3}{4}\text{ = }\frac{r-4}{-1-3}

we can now simplify and then solve for r

\frac{-3}{4}\text{ = }\frac{r-4}{-4}

cross-multiply

-3 x -4 = 4(r-4)

12 = 4(r-4)

Divide both-side of the equation by 4

\frac{12}{4}\text{ = }\frac{4(r-4)}{4}

3 = r - 4

add 4 to both-side of the equation

3+4 = r-4+4

7 = r

r=7

Therefore the value of r is 7
