Answer:

To round, you look at the number that is before the place you are rounding. If that number is 5 or higher, the place you are rounding goes up by one. If the number before the place is 4 or lower, the place you are rounding stays the same.

Find the area of a triangle formed by placing the vectors [3, 6] and [7, 1] tail-to-tail.

Usimov [2.4K]

Answer:

a. $A=10u^{2}$

b. View graph

c. 6.40u

Step-by-step explanation:

knowing that the triangle area is equal to base by heigh between two, then:

$A=\frac{bh}{2}=\frac{5*4}{2}=10u^{2}$

The length of the longest altitude of your triangle is:

$c^{2}=a^{2}+b^{2}=5^{2}+4^{2}=25+16=41\\ c=\sqrt{41}=6.40u$

finally it can be seen that the position of the triangle does not matter, as long as the base and heigh are maintained, the area of the triangle will be the same

Math number 12 <br><br> Find the value of x

mario62 [17]

Answer:

Step-by-step explanation:

LN = 4 + x - 8 = x - 4

LS = 3 + x - 5 = x - 2

By intersecting secants theorem:

$LM\times LN = LK\times LS \\ \\ 4(x - 4) = 3(x - 2) \\ \\ 4x - 16 = 3x - 6 \\ \\ 4x - 3x = 16 - 6 \\ \\ x = 10$

Makovka662 [10]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

a.) Value of log 32 ~

$log(32)$

$log(2) {}^{5}$

$5 \times log(2)$

$5 \times 0.3010$

$1.505$

b.) Value of log 40 ~

$log(40)$

$log(10 \times 4)$

$log(10) + log(4)$

$1 + 2 log(2)$

$1 + (2 \times 0.3010)$

$1 + 0.6020$

$1.6020$

I hope it helps ~
