Answer:

a = 0 ; a = -10

Step-by-step explanation:

a squared number give as result a positive number, either if it is positive or negative

we have to find two numbers whose square is 25: these numbers are 5 and -5

a+5 = 5

a = 0

a+5 = -5

a = -10

Answer:

(a+5)^2=25 means a^2+5^2=25, a^2=25-25 then a^2=√0, a=0

Answer:

Step-by-step explanation:

$2\frac{1}{5}dividedby\frac{-1}{10}=2\frac{1}{5}*\frac{-10}{1}\\\\=\frac{11}{5}*\frac{-10}{1}\\\\=11*-2=-22\\$

Keep the first fraction, change division to multiplication and find the reciprocal(multiplicative inverse) of the second fraction

$\frac{11}{50}dividedby\frac{11}{50}=\frac{11}{50}*\frac{50}{11}\\\\ =1$

Write the number 3.8 in the form , using integers, to show that it is a rational number.

Answer:

3.8 = 38/10 = 19/5

Step-by-step explanation:

You can always represent a terminating decimal number as the ratio of integers. Count the number of decimal places, and multiply and divide it by 10 to that power. If you like, you can reduce the resulting fraction. 3.8 has 1 decimal place, so our chosen power of 10 is 10¹.

3.8 = (3.8×10¹)/(10¹) = 38/10 = 19/5

Data for the estimated number of HIV cases worldwide between 1988 and 1996 suggests exponential growth in the number of cases ov

Eduardwww [97]

Answer:

d. 52.5 million cases

Step-by-step explanation:

from the data output in the question, we have the regression equation to be

log y = -151.281 + 0.076577x

y is the number of hiv cases which is in millions

x is the year of the hiv case

x = 1998

we put the value of x in the regression equation

log y = -151.281 + 0.076577(1998)

log y = -151.281 + 153.000846

log y = 1.719846

since the result is in log form,

$y=10^{1.791846}$

y = 52.5 million cases
