10 .find the partial sum S10 of the arithmetic series with a1 = 4, d = 5.
Crazy boy [7]

Answer:

S10 = 320

Step-by-step explanation:

The formula for calculating the sum of the nth term of an AP is expressed as

Sn = n/2(2a+(n-1)d))

Given

a = 4

d = 5

n = 10

S10 =10/2{2(5)+(10-1)5}

S10 =5{10+9(6)}

S10 =5{10+54}

S10 = 5(64)

S10 = 320

Hence the sum of the first ten terms of the sequence is 320

If Q = 44°<br> then m ST = ______ degrees<br> R = _____ degrees
melomori [17]

Basically, Q is an angle. An angle has an initial side and a terminal side. The initial side is QS, The terminal side is QT. The initial side and the terminal side both intersect the circle. The initial side intersects the circle at point S. The terminal side intersects the circle at point T. This forms arc TS.
<span>Angle Q is what is known as an inscribed angle. Anytime you have an inscribed angle, it will always cut across some arc. The measure of that angle will always be 1/2 the measure of the arc.
</span><span>We're given that angle Q = 44 degrees. This means that the measure of arc TS will be twice the measure of angle Q.
</span>

angle(q)=angle(r) so ans =44

Y= |x−3| + |x+2| − |x−5|, if x&gt;5<br> I need to know what y equals.
olganol [36]

Answer:

y  \ge9

Step-by-step explanation:

The given function is

y =  |x - 3|   +  |x  + 2|  -  |x - 5|

By the triangle inequality property,

|x + y|  \leqslant  |x|  +  |y|

and the alternate triangle inequality property;

|x - y|  \geqslant  |x|  -  |y|

We apply this property to get:

y  \geqslant   |x |    - |3|    +  |x |  +  |2|  -(  |x |  -  |5| )

Expand parenthesis to get:

y  \geqslant   |x |    - |3|    +  |x |  +  |2|  - |x |   +   |5|

Simplify to get:

y  \geqslant   |x |    - 3+  |x |  +  2- |x |   +   5

Group similar terms to get:

y  \geqslant   |x |  +   |x | - |x |    - 3 + 2+   5

y  \geqslant   |x |   + 4

When x>5,

y  \geqslant   |5 |   + 4

That's;

y  \geqslant   5  + 4   \\ y  \geqslant   9
