We have an arithmetic sequence with 

<span>a0 = 1st 3-digit number divisible by 13 </span>
<span>a0 = 104 </span>
<span>d = 13 (why?) </span>
<span>last term is largest divisible by 13 = 988 </span>
<span>how many terms? (988-104)/13 + 1 = 69 </span>

<span>S = 69/2(104+988) = 37674</span>

Answer:

10.02 units

Step-by-step explanation:

FH = \frac{82}{360} \times 2 \pi r (Multiplying the circumference of the circle by the arc's degree over the total degree of the circle will find the length of the arc FH)

FH = \frac{82}{360}\times 2 \pi (7)

=\frac{82}{360}\times14\pi

=\frac{287\pi}{90}

=10.02 (to the nearest hundredth)

∴ The length of the arc FH is 10.02 units to the nearest hundredth.

Hope this helps :)

The expression 1.5*1.09 models the housing costs, in thousands of dollars, for summer term t years since Chinedu applied to his
Alex777 [14]

Answer: Multiplicative rate of change in housing costs, for summer term t years since Chinedu applied to his college.

Step-by-step explanation:

Given: 1.5\times1.09^t models the housing costs, in thousands of dollars, for summer term t years since Chinedu applied to his college.

Since, the above expression is an exponential function. [ t is the exponent ]

The standard exponential function is given by :-

y=Ab^x, A is the initial amount , b is the multiplicative rate of change with respect to time period x.

as compare to the given expression, we get b= 1.09, which is the multiplicative rate of change in the housing costs, for summer term t years since Chinedu applied to his college.

The coordinates of a quadrilateral are (2,1), (-1,3), (-5,-3), and (-2,-5).
Vlad [161]

The quadrilateral is a <u>parallelogram</u> because <u>both pairs of opposite sides</u> are parallel and since the product of the slopes of both pairs of <u>adjacent</u> segments is -1, the quadrilateral is a <u>rectangle</u>
